Soil salinity significantly limits rice productivity, but it is poorly understood how excess sodium (Na+) is delivered to the grains at the reproductive stage. Here, we functionally characterized OsHAK4, a member of the clade IV HAK/KUP/KT transporter subfamily in rice. OsHAK4 was localized to the plasma membrane and exhibited influx transport activity for Na+, but not for K+. Analysis of organ- and growth stage-dependent expression patterns showed that very low expression levels of OsHAK4 were detected at the vegetative growth stage, but its high expression in uppermost node I, peduncle, and rachis was found at the reproductive stage. Immunostaining indicated OsHAK4 localization in the phloem region of node I, peduncle, and rachis. Knockout of OsHAK4 did not affect the growth and Na+ accumulation at the vegetative stage. However, at the reproductive stage, the hak4 mutants accumulated higher Na+ in the peduncle, rachis, husk, and brown rice compared to the wild-type rice. Element imaging revealed higher Na+ accumulation at the phloem region of the peduncle in the mutants. These results indicate that OsHAK4 plays a crucial role in retrieving Na+ from the phloem in the upper nodes, peduncle, and rachis, thereby preventing Na+ distribution to the grains at the reproductive stage of rice.

Language：English Publishing type：Research paper (scientific journal)

Plants take up metals, including the essential micronutrients [iron (Fe), copper (Cu), zinc (Zn), and manganese (Mn)] and the toxic heavy metal cadmium (Cd), from soil and accumulate these metals in their edible parts, which are direct and indirect intake sources for humans. Multiple transporters belonging to different families are required to transport a metal from the soil to different organs and tissues, but only a few of them have been fully functionally characterized. The transport systems (the transporters required for uptake, translocation, distribution, redistribution, and their regulation) differ with metals and plant species, depending on the physiological roles, requirements of each metal, and anatomies of different organs and tissues. To maintain metal homeostasis in response to spatiotemporal fluctuations of metals in soil, plants have developed sophisticated and tightly regulated mechanisms through the regulation of transporters at the transcriptional and/or posttranscriptional levels. The manipulation of some transporters has succeeded in generating crops rich in essential metals but low in Cd accumulation. A better understanding of metal transport systems will contribute to better and safer crop production. Expected final online publication date for the Annual Review of Plant Biology, Volume 75 is May 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Language：English Publishing type：Research paper (scientific journal)

To play essential roles of manganese (Mn) in plant growth and development, it needs to be transported to different organs and tissues after uptake. However, the molecular mechanisms underlying Mn distribution between different tissues are poorly understood. We functionally characterized a member of rice natural resistance-associated macrophage protein (NRAMP) family, OsNramp5 in terms of its tissue specificity of gene expression, cell-specificity of protein localization, phenotypic analysis of leaf growth and response to Mn fluctuations. OsNramp5 is highly expressed in the leaf sheath. Immunostaining revealed that OsNramp5 is polarly localized at the proximal side of xylem parenchyma cells of the leaf sheath. Both the gene expression and protein abundance of OsNramp5 are unaffected by different Mn concentrations. Knockout of OsNramp5 decreased the distribution of Mn to the leaf sheath, but increased the distribution to the leaf blade at both low and high Mn supplies, resulting in reduced growth of leaf sheath. Furthermore, expression of OsNramp5 under the control of root-specific promoter in osnramp5 mutant complemented Mn uptake, but could not complement Mn distribution to the leaf sheath. These results indicate that OsNramp5 expressed in the leaf sheath plays an important role in unloading Mn from the xylem for the local distribution in rice.

Rice is a staple food for half world's population, but it is a poor dietary source of calcium (Ca) due to its low concentration. Therefore, it is an important issue to boost the Ca concentration in the grain for improving Ca deficiency risk, but the mechanisms underlying the Ca accumulation are poorly understood. Here, we obtained a rice (Oryza sativa) mutant with high shoot Ca accumulation. The mutant exhibited 26-53% higher Ca in the shoots than that in wild-type rice (WT) at different Ca supplies. The Ca concentration in the xylem sap was 36% higher in the mutant than in the WT. There was no difference in agronomic traits between the WT and mutant, but the mutant showed 25% higher Ca in the polished grain compared with the WT. Map-based cloning combined with complementation test revealed that the mutant phenotype was caused by an 18-bp deletion of a gene, OsK5.2 belonging to Shaker-like K+ channel family. OsK.2 was highly expressed in the mature region of the roots and its expression in the roots was not affected by Ca levels, but up-regulated by low K. Immunostaining showed that OsK.2 was mainly expressed in pericycle of the roots. Taken together, our results revealed a novel role of OsK.2 in Ca translocation in rice, which will be a good target for Ca biofortification in rice. This article is protected by copyright.

Silicon (Si) is the most abundant mineral element in the earth's crust. Some plants actively accumulate Si as amorphous silica (phytoliths), which can protect plants from stresses. Here, we report a gene (SIET4) that is required for the proper accumulation and cell-specific deposition of Si in rice and show that it is essential for normal growth. SIET4 is constitutively expressed in leaves and encodes a Si transporter. SlET4 polarly localizes at the distal side of epidermal cells and cells surrounding the bulliform cells (motor cells) of the leaf blade, where Si is deposited. Knockout of SIET4 leads to the death of rice in the presence but not absence of Si. Further analysis shows that SIET4 knockout induces abnormal Si deposition in mesophyll cells and the induction of hundreds of genes related to various stress responses. These results indicate that SIET4 is required for the proper export of Si from leaf cells to the leaf surface and for the healthy growth of rice on land.

Rice grain is a poor dietary source of zinc (Zn) but the primary source of cadmium (Cd) for humans; however, the molecular mechanisms for their accumulation in rice grain remain incompletely understood. This study functionally characterized a tonoplast-localized transporter, OsMTP1. OsMTP1 was preferentially expressed in the roots, aleurone layer, and embryo of seeds. OsMTP1 knockout decreased Zn concentration in the root cell sap, roots, aleurone layer and embryo, and subsequently increased Zn concentration in shoots and polished rice (endosperm) without yield penalty. OsMTP1 haplotype analysis revealed elite alleles associated with increased Zn level in polished rice, mostly because of the decreased OsMTP1 transcripts. OsMTP1 expression in yeast enhanced Zn tolerance but did not affect that of Cd. While OsMTP1 knockout resulted in decreased uptake, translocation and accumulation of Cd in plant and rice grain, which could be attributed to the indirect effects of altered Zn accumulation. Our results suggest that rice OsMTP1 primarily functions as a tonoplast-localized transporter for sequestrating Zn into vacuole. OsMTP1 knockout elevated Zn concentration but prevented Cd deposition in polished rice without yield penalty. Thus, OsMTP1 is a candidate gene for enhancing Zn level and reducing Cd level in rice grains.

Language：English Publishing type：Research paper (scientific journal)

Silicon (Si) is important for stable and high yields in rice (Oryza sativa), a typical Si hyperaccumulator. The high Si accumulation is achieved by the cooperation of 2 Si transporters, LOW SILICON 1 (OsLsi1) and OsLsi2, which are polarly localized in cells of the root exodermis and endodermis. However, the mechanism underlying their polar localization is unknown. Here, we identified amino acid residues critical for the polar localization of OsLsi1. Deletion of both N- and C-terminal regions resulted in the loss of its polar localization. Furthermore, the deletion of the C-terminus inhibited its trafficking from the endoplasmic reticulum to the plasma membrane. Detailed site-directed mutagenesis analysis showed that Ile18 at the N-terminal region and Ile285 at the C-terminal region were essential for the polar localization of OsLsi1. Moreover, a cluster of positively charged residues at the C-terminal region is also required for polar localization. Phosphorylation and Lys modifications of OsLsi1 are unlikely to be involved in its polar localization. Finally, we showed that the polar localization of OsLsi1 is required for the efficient uptake of Si. Our study not only identified critical residues required for the polar localization of OsLsi1, but also provided experimental evidence for the importance of transporter polarity for efficient nutrient uptake.

FE UPTAKE-INDUCING PEPTIDE1 (FEP1), also named IRON MAN3 (IMA3) is a short peptide involved in the iron deficiency response in Arabidopsis thaliana. Recent studies uncovered its molecular function, but its physiological function in the systemic Fe response is not fully understood. To explore the physiological function of FEP1 in iron homoeostasis, we performed a transcriptome analysis using the FEP1 loss-of-function mutant fep1-1 and a transgenic line with oestrogen-inducible expression of FEP1. We determined that FEP1 specifically regulates several iron deficiency-responsive genes, indicating that FEP1 participates in iron translocation rather than iron uptake in roots. The iron concentration in xylem sap under iron-deficient conditions was lower in the fep1-1 mutant and higher in FEP1-induced transgenic plants compared with the wild type (WT). Perls staining revealed a greater accumulation of iron in the cortex of fep1-1 roots than in the WT root cortex, although total iron levels in roots were comparable in the two genotypes. Moreover, the fep1-1 mutation partially suppressed the iron overaccumulation phenotype in the leaves of the oligopeptide transporter3-2 (opt3-2) mutant. These data suggest that FEP1 plays a pivotal role in iron movement and in maintaining the iron quota in vascular tissues in Arabidopsis.

Language：English Publishing type：Research paper (scientific journal)

The roots of many plant species contain large amounts of pectin and it contributes to the formation of the rhizosphere. In the present study, the relationship between the root-tip pectin content and aluminium (Al) tolerance in wild-type (WT) and demethylesterified pectin degradation enzyme gene overexpressor (OsPG2-FOX) rice lines was compared. OsPG2-FOX rice showed reduced pectin content in roots, even under control conditions; Al treatment reduced root elongation and the pectin content in the root elongation zone. Wild-type rice showed more pectin accumulation in the root elongation zone after Al treatment. Relative to WT rice, OsPG2-FOX rice showed more Al accumulation in the root elongation zone. These results indicate that the amount of pectin influences Al tolerance and that the distribution of pectin in the root elongation zone inhibits Al accumulation in rice roots. Pectin accumulation in cell walls in the root elongation zone may play a role in protecting rice plants from the Al-induced inhibition of root elongation by regulating pectin distribution.

Grains are the major sink of phosphorus (P) in cereal crops, accounting for 60-85% of total plant P, but the mechanisms underlying P loading into the grains are poorly understood. We functionally characterized a transporter gene required for the distribution of P to the grains in barley (Hordeum vulgare), HvSPDT (SULTR-like phosphorus distribution transporter). HvSPDT encoded a plasma membrane-localized Pi/H+ cotransporter. It was mainly expressed in the nodes at both the vegetative and reproductive stages. Furthermore, its expression was induced by inorganic phosphate (Pi) deficiency. In the nodes, HvSPDT was expressed in both the xylem and phloem region of enlarged and diffuse vascular bundles. Knockout of HvSPDT decreased the distribution of P to new leaves, but increased the distribution to old leaves at the vegetative growth stage under low P supply. However, knockout of HvSPDT did not alter the redistribution of P from old to young organs. At the reproductive stage, knockout of HvSPDT significantly decreased P allocation to the grains, resulting in a considerable reduction in grain yield, especially under P-limited conditions. Our results indicate that node-based HvSPDT plays a crucial role in loading P into barley grains through preferentially distributing P from the xylem and further to the phloem.

<title>Abstract</title>
Uptake of boron (B) in rice (Oryza sativa) is mediated by the Low silicon rice 1 (OsLsi1) channel, belonging to the NOD26-like intrinsic protein III subgroup, and the efflux transporter B transporter 1 (OsBOR1). However, it is unknown how these transporters cooperate for B uptake and how they are regulated in response to B fluctuations. Here, we examined the response of these two transporters to environmental B changes at the transcriptional and posttranslational level. OsBOR1 showed polar localization at the proximal side of both the exodermis and endodermis of mature root region, forming an efficient uptake system with OsLsi1 polarly localized at the distal side of the same cell layers. Expression of OsBOR1 and OsLsi1 was unaffected by B deficiency and excess. However, although OsLsi1 protein did not respond to high B at the protein level, OsBOR1 was degraded in response to high B within hours, which was accompanied with a significant decrease of total B uptake. The high B-induced degradation of OsBOR1 was inhibited in the presence of MG-132, a proteasome inhibitor, without disturbance of the polar localization. In contrast, neither the high B-induced degradation of OsBOR1 nor its polarity was affected by induced expression of dominant-negative mutated dynamin-related protein 1A (OsDRP1AK47A) or knockout of the mu subunit (AP2M) of adaptor protein-2 complex, suggesting that clathrin-mediated endocytosis is not involved in OsBOR1 degradation and polar localization. These results indicate that, in contrast to Arabidopsis thaliana, rice has a distinct regulatory mechanism for B uptake through clathrin-independent degradation of OsBOR1 in response to high B.

Language：English Publishing type：Research paper (scientific journal)

Zinc (Zn) is an essential micronutrient for both plants and animals, while Zn deficiency in crops and humans is a global problem affecting crop productivity and human health. Since plants and humans differ in their Zn requirement, there is a dilemma between plant nutrition and human nutrition. In this review, we focus on the transport system of Zn from soil to grain in rice (Oryza sativa), which is a major dietary source of Zn for people subsiding on rice-based diets. We describe transporters belonging to different family, which are involved in the uptake, vacuolar sequestration, root-to-shoot translocation and distribution of Zn. We also discuss the possible regulation mechanism of these transporters. Several examples are given on enhancing Zn accumulation and bioavailability in rice grains through manipulation of genes highly expressed in the nodes, where Zn is highly deposited. We finally provide our perspectives toward breeding rice cultivars with both increased tolerance to Zn-deficiency stress and high Zn density in rice grains.

Silicon (Si), the most abundant mineral element in the earth's crust, is taken up by plant roots in the form of silicic acid through Low silicon rice 1 (Lsi1). Lsi1 belongs to the Nodulin 26-like intrinsic protein subfamily in aquaporin and shows high selectivity for silicic acid. To uncover the structural basis for this high selectivity, here we show the crystal structure of the rice Lsi1 at a resolution of 1.8 Å. The structure reveals transmembrane helical orientations different from other aquaporins, characterized by a unique, widely opened, and hydrophilic selectivity filter (SF) composed of five residues. Our structural, functional, and theoretical investigations provide a solid structural basis for the Si uptake mechanism in plants, which will contribute to secure and sustainable rice production by manipulating Lsi1 selectivity for different metalloids.

Rice (Oryza sativa L.) can accumulate high manganese (Mn) in the shoots through uptake by the roots, which consist of crown roots, lateral roots and root hairs. We investigated the role of lateral roots and root hairs in Mn and cadmium (Cd) uptake by using two indica rice mutants defective in formation of lateral roots (osiaa11) and root hairs (osrhl1). The uptake of Mn and Cd in osiaa11 was significantly lower than that in wild type 'Kasalath', but there was no difference between wild type and osrhl1. Furthermore, a kinetic study showed that Mn uptake in osiaa11 was much lower than that in wild type and osrhl1 across a wide range of Mn concentrations. The role of lateral roots in Mn and Cd uptake was further confirmed in a japonica rice mutant defective in lateral root formation. We found that expression of Mn transporter gene Natural Resistance-Associated Macrophage Protein 5 (OsNRAMP5), but not of Metal Tolerance Protein 9 (OsMTP9), was lower in osiaa11 than in wild type; however, there were no differences between osrhl1 and the wild type. Immunostaining showed that OsNRAMP5 and OsMTP9 were localized in the exodermis and endodermis of crown roots and lateral roots, but not in the root hairs. Taken together, our results indicate that lateral roots, but not root hairs, play an important role in high Mn and Cd uptake in rice.

Observing chromosomes is a time-consuming and labor-intensive process, and chromosomes have been analyzed manually for many years. In the last decade, automated acquisition systems for microscopic images have advanced dramatically due to advances in their controlling computer systems, and nowadays, it is possible to automatically acquire sets of tiling-images consisting of large number, more than 1000, of images from large areas of specimens. However, there has been no simple and inexpensive system to efficiently select images containing mitotic cells among these images. In this paper, a classification system of chromosomal images by deep learning artificial intelligence (AI) that can be easily handled by non-data scientists was applied. With this system, models suitable for our own samples could be easily built on a Macintosh computer with Create ML. As examples, models constructed by learning using chromosome images derived from various plant species were able to classify images containing mitotic cells among samples from plant species not used for learning in addition to samples from the species used. The system also worked for cells in tissue sections and tetrads. Since this system is inexpensive and can be easily trained via deep learning using scientists' own samples, it can be used not only for chromosomal image analysis but also for analysis of other biology-related images.

Manganese (Mn) is an essential element for plant growth and development, but transporters required for Mn uptake have only been identified in a few plant species. Here, we functionally characterized a member of the natural resistance-associated macrophage proteins (Nramps) family, FeNramp5 in buckwheat (Fagopyrum esculentum Moench), which is known as a species well adapted to acidic soils. FeNramp5 was mainly expressed in the roots, and its expression was upregulated by the deficiency of Mn and Fe. Furthermore, spatial and tissue-specific expression analysis showed that FeNramp5 was expressed in all tissues of the basal root regions. FeNramp5-GFP protein was localized to the plasma membrane when transiently expressed in buckwheat leaf protoplast. FeNramp5 showed the transport activity for Mn2+ and Cd2+ but not for Fe2+ when expressed in yeast. Furthermore, the transport activity for Mn2+ was higher in yeast expressing FeNramp5 than in yeast expressing AtNramp1. FeNramp5 was also able to complement the phenotype of Arabidopsis atnramp1 mutant in terms of the growth and accumulation of Mn and Cd. The absolute expression level of AtNramp1 was comparable to that of FeNramp5 in the roots, but buckwheat accumulated higher Mn than Arabidopsis when grown under the same condition. Further analysis showed that at least motif B in FeNramp5 seems important for its high transport activity for Mn. These results indicate that FeNramp5 is a transporter for the uptake of Mn and Cd and its higher transport activity for Mn is probably associated with higher Mn accumulation in buckwheat.

Language：English

About 60-85% of total phosphorus (P) in cereal crops is finally allocated to seeds, where it is required for seed development, germination and early growth. However, little is known about the molecular mechanisms underlying P allocation to seeds. Here, we found that two members (OsPHO1;1 and OsPHO1;2) of the PHO1 gene family are involved in the distribution of P to seeds in rice. Both OsPHO1;1 and OsPHO1;2 were localized to the plasma membrane and showed influx transport activities for inorganic phosphate. At the reproductive stage, both OsPHO1;1 and OsPHO1;2 showed higher expression in node I, the uppermost node connecting to the panicle. OsPHO1;1 was mainly localized at the phloem region of diffuse vascular bundles (DVBs) of node I, while OsPHO1;2 was expressed in the xylem parenchyma cells of the enlarged vascular bundles (EVBs). In addition, they were also expressed in the ovular vascular trace, the outer layer of the inner integument (OsPHO1;1) and in the nucellar epidermis (OsPHO1;2) of caryopses. Knockout of OsPHO1;2, as well as OsPHO1;1 to a lesser extent, decreased the distribution of P to the seed, resulting in decreased seed size and delayed germination. Taken together, OsPHO1;2 expressed in node I is responsible for the unloading of P from the xylem of EVBs, while OsPHO1;1 is involved in reloading P into the phloem of DVBs for subsequent allocation of P to seeds. Furthermore, OsPHO1;1 and OsPHO1;2 expression in the caryopsis is important for delivering P from the maternal tissues to the filial tissues for seed development.

Retrotransposon Insertion and DNA Methylation Regulate Aluminum Tolerance in European Barley Accessions. Reviewed International journal

Language：English

Aluminum (Al) toxicity is a major stress factor limiting crop productivity in acid soil. Although there is great genotypic variation in tolerance to Al toxicity, the underlying molecular mechanisms are poorly understood. Here, we report that, in barley (Hordeum vulgare), the fourth largest cereal crop produced in the world, both retrotransposon insertion and DNA methylation are involved in regulating differential Al tolerance. HvAACT1 is a major gene responsible for citrate secretion from the roots for external detoxification of Al. A multiretrotransposon-like (MRL) sequence insertion at least 15.3 kb in length was detected in the upstream genomic region of HvAACT1 that displayed promoter activity and significantly enhanced HvAACT1 expression, especially in the root tips of Al-tolerant accessions. Furthermore, in a number of accessions with low levels of HvAACT1 expression, this MRL insertion was present but highly methylated. Geographical analysis showed that accessions with this MRL insertion are distributed mainly in European areas with acid soils. Two wild barley accessions were found to possess this MRL insertion, but with a high degree of methylation. These results indicate that the MRL insertion and its degree of DNA methylation influence HvAACT1 expression and that demethylation of this MRL insertion, which facilitates adaptation to acid soils, occurred following barley domestication. Moreover, our results indicate that barley accessions in East Asia and Europe have developed independent but equivalent strategies to withstand Al toxicity in acid soils.

Language：English

Originating from the Fertile Crescent in the Middle East, barley has now been cultivated widely on different soil types including acid soils, where aluminium toxicity is a major limiting factor. Here we show that the adaptation of barley to acid soils is achieved by the modification of a single gene (HvAACT1) encoding a citrate transporter. We find that the primary function of this protein is to release citrate from the root pericycle cells to the xylem to facilitate the translocation of iron from roots to shoots. However, a 1-kb insertion in the upstream of the HvAACT1 coding region occurring only in the Al-tolerant accessions, enhances its expression and alters the location of expression to the root tips. The altered HvAACT1 has an important role in detoxifying aluminium by secreting citrate to the rhizosphere. Thus, the insertion of a 1-kb sequence in the HvAACT1 upstream enables barley to adapt to acidic soils.

Soluble ionic aluminum (Al) inhibits root growth and reduces crop production on acid soils. Al-resistant cultivars of barley (Hordeum vulgare L.) detoxify Al by secreting citrate from the roots, but the responsible gene has not been identified yet. Here, we identified a gene (HvAACT1) responsible for the Al-activated citrate secretion by fine mapping combined with microarray analysis, using an Al-resistant cultivar, Murasakimochi, and an Al-sensitive cultivar, Morex. This gene belongs to the multidrug and toxic compound extrusion (MATE) family and was constitutively expressed mainly in the roots of the Al-resistant barley cultivar. Heterologous expression of HvAACT1 in Xenopus oocytes showed efflux activity for (14)C-labeled citrate, but not for malate. Two-electrode voltage clamp analysis also showed transport activity of citrate in the HvAACT1-expressing oocytes in the presence of Al. Overexpression of this gene in tobacco enhanced citrate secretion and Al resistance compared with the wild-type plants. Transiently expressed green fluorescent protein-tagged HvAACT1 was localized at the plasma membrane of the onion epidermal cells, and immunostaining showed that HvAACT1 was localized in the epidermal cells of the barley root tips. A good correlation was found between the expression of HvAACT1 and citrate secretion in 10 barley cultivars differing in Al resistance. Taken together, our results demonstrate that HvAACT1 is an Al-activated citrate transporter responsible for Al resistance in barley.

Publisher：The Japanese Society of Plant Physiologists

Buckwheat is not only highly tolerant to Al, but also accumulates Al at high concentration in the shoots. Physiological studies have shown that buckwheat secretes oxalate in response to Al and sequesters Al into the vacuoles in the leaves. Many transporters are proposed to be involved in these processes, but none of them has been identified so far. To identify these transporters, we established an EST library of buckwheat roots. Sequence analysis with next generation sequencer and short-gun analysis generated 100,000 reading contigs and as well as the gene expression level. In the present study, we focus on FeIREG2, which showed higher expression in transporter candidate genes. The full length of this gene shows 60% similarity with Arabidopsis IREG2, which is a tonoplast-localized efflux transporter of Fe, Co and Ni. FeIREG2 was expressed in the buckwheat roots and the expression was greatly induced by Al. Transient assay using FeIREG2-GFP fusion showed that this protein is localized to the tonoplast. Based on these evidences, we propose that FeIREG2 might be involved in the sequestration of Al into vacuoles in buckwheat. Further characterization of this gene is being undertaken.

Transporters involved in transport and detoxification of minerals in plants

Language：Japanese Publisher：The Japanese Society for Chemical Regulation of Plants

Plants are characterized by mineral nutrition, which require 17 essential elements for their growth. Among them, 14 are minerals. These minerals are taken up by the roots, translocated from the roots to the shoots and finally distributed to different cells for functions. A large number of transporters is required for these transport processes. On the other hand, plants are exposed to toxic minerals, therefore detoxification of these minerals by plants at different cellular levels is also required for survival. Herein, we reviewed recent progresses in identification of transporters involved in uptake, translocation, and distribution of essential minerals and of transporters involved in the detoxification of toxic minerals, focusing on iron (Fe), silicon (Si) and aluminum (Al), which represent essential, beneficial and toxic minerals, respectively.

Isolation and characterization of two MATE genes in rye

Publisher：The Japanese Society of Plant Physiologists

Multidrug and toxic compound extrusion (MATE) proteins are widely present in bacteria, fungi, plants and mammals. Recent studies have showed that a group of plant MATE genes encodes citrate transporter, which are involved in the Al detoxification or Fe translocation from the roots to the shoots. In this study we isolated two homologous genes (ScFRDL1 and ScFRDL2) of this-type MATE in rye. ScFRDL1 shared 94 % identity with barley Al-induced citrate transporter HvAACT1 and ScFRDL2 shared 80 % identity with rice Al-induced gene OsFRDL2. Both genes were expressed in the roots, however, they showed different expression pattern. The expression of ScFRDL1 was unaffected by Al treatment, but induced by Fe-deficiency. By contrast, the expression of ScFRDL2 was induced by Al but not by Fe deficiency. Furthermore, the expression pattern of OsFRDL2 was consistent with citrate secretion pattern. Immunostaining showed that ScFRDL1 is localized at central cylinder in the basal roots. Taken together, our results suggest that ScFRDL1 is involved in efflux of citrate into the xylem for Fe translocation from root to shoot, while ScFRDL2 is involved in Al-activated citrate secretion in rye.

Functional analysis of OsFRDL4, a citrate transporter involved in Al tolerance in rice

Publisher：The Japanese Society of Plant Physiologists

We recently characterized two MATE genes, HvAACT1 and OsFRDL1, which both are citrate transporter in barley and rice. HvAACT1 is involved in the Al-induced citrate secretion, while OsFRDL1 is involved in Fe translocation from the roots to the shoots. Here we report the function of a homolog of OsFRDL1, OsFRDL4, in rice. We first compared the phenotype between the wild-type and a Tos17 insertion line. Knockout of this gene did not cause chlorosis and decreased concentration of Fe and citrate in the xylem sap, but resulted in decreased Al-induced secretion of citrate from the roots. The protein encoded by this gene was able to transport citrate out of cell. All our results indicate that OsFRDL4 is a citrate transporter, which is involved in the Al-induced citrate secretion in rice. However, different from HvAACT1, which expression is not induced by Al, the expression of OsFRDL4 is greatly induced by Al.

We recently identified an Al-tolerant gene (HvAACT1) from barley, which encodes an Al-activated citrate transporter. Here, we report the closest homolog of this gene in rice (OsFRDL1). We compared the Al-induced citrate secretion between the wild-type rice and Tos-17 insertion lines. However, there was no difference in the citrate secretion between these lines. When these lines were grown in a nutrient solution with low Fe concentration, chlorosis on the new leaves was observed only in the knocknot lines. The concentration of Fe and citrate in the xylem sap was much lower and Fe precipitation in the root stele was observed in the knockout line. The protein encoded by this gene showed transport activity for citrate. This gene was expressed in the roots and the expression level was not affected by Fe nutrition. These results suggest that OsFRDL1 is a citrate transporter, which is necessary for Fe translocation to the shoot.

イネのカドミウム品種間差を利用して作出したマッピング集団を用いて、新しいマーカーを作成しながら、染色体7番と11番のQTL遺伝子の候補領域を狭めることができた。7番染色体にあるQTL遺伝子についてプロモーター領域配列の比較、発現パータンの比較などを行い、この遺伝子の発現の違いがカドミウム集積に寄与している可能性を示した。またカドミウム集積における側根と根毛の役割を解析し、根毛ではなく、側根がカドミウムの吸収に大きな役割を果たしていることを明らかにした。
ヒ素集積に関して、6番染色体にあるヒ素集積に関与するQTL遺伝子の候補領域を350kbまで狭めることができた。
2．オオムギのカドミウム集積QTL遺伝子のマッピングとヒ素集積の品種間差
オオムギのカドミウム集積の品種間差を利用して、4番染色体にあるカドミウム集積に関与するQTL遺伝子のマッピングを行った。いくつかのマーカーを新たに設計し、候補領域を8375kbまで狭めることができた。
またオオムギヒ素集積の品種間差を調べるために、コアコレクションから100品種を選んで、圃場栽培された種子とわら中のヒ素濃度を測定し、比較した。その結果、ヒ素集積において大きな品種間差があることが分かった。また水耕栽培で幼苗のヒ素集積も比較し、種子のヒ素集積と必ず一致しないことを明らかにした。いくつか集積が大きく異なる品種を選んで、関連遺伝子をマッピングするための交配を行った。

We focused on the microbial functions to explain sustainability of rice-barley double cropping, which has been utilized for long in west-south part of Japan including Okayama. We visualized the field environmental factors including microbiome structure of three years in the experimental fields. 16S rRNA amplicon sequencing analysis of 2400 samples was done for the soil, rhizosphere soil, and root samples of two different rice and barley cultivars (total 4 cultivars) grown in the fertilized and non-fertilized fields. The microbiome structures that have different structures depending on the part of samples (root, rhizosphere, and soil) were distinct between rice and barley that repeated well in three years, and they were also affected by fertilization. Soil solutes analysis also revealed that it is affected by fertilization. Also we got data of wild plant species and physicochemical factors. These data serves as a basis to develop sustainable agriculture.

イネ科植物は「節」を構成単位とするモジュール化された体制を採用しており、節には栄養素の分配や成長/休眠の制御などの機能が高度に集約されていることから、個体レベルの環境応答においても様々なシグナルの受発信/変換/転送を担う主要な情報処理の場であると考えられる。
本年度は、節の環境応答に関与する遺伝子を見出すため、出穂期のイネに対し、短期的なストレス処理を行った最上位節(節I)と下位節(節V~VI)の次世代シーケンサーを用いたRNA-seq解析を実施した。各処理区で発現が有意に変動した転写調節因子、受容体、ペプチドホルモン、などをコードする数十の機能未知遺伝子を選抜した(一次選抜)。さらに定量的RT- PCRによるより詳細な遺伝子発現解析を行い、既存の発現データベース等の情報も加味して検討した結果、節において他の器官よりも特に発現レベルが高く、いずれかのストレス処理に顕著に応答する13の遺伝子を選抜した(二次選抜)。これらの遺伝子についてCRISPR/Cas9法による遺伝子破壊株の作出を進めている。
イネ節の肥大維管束木部転送細胞に極めて高発現し、ケイ酸の分配を制御する輸送体Lsi6の遺伝子発現を制御する転写調節因子の探索については、酵母one-hybridシステムによるスクリーニングを計画していたが、Lsi6プロモーターの候補領域が酵母において著しい偽陽性を生じることが判明した。

We have identified more than 30 transporter genes related to uptake, translocation and distribution of mineral elements including essential, beneficial and toxic elements mainly in rice and buckwheat. We further revealed the mechanisms for response of these transporters to environmental changes, regulation of transporters and their roles in plant growth and productivity by using different approaches. For the first time, we succeeded to crystalize the silicon transporter Lsi1 and revealed its crystal structure. We also constructed a mathematical model for mineral element transport at whole plant scales. These achievements have been published in many international top journals including Nature.

Soil pH has a large impact on availability of mineral elements. For example, at a low pH, Al is solubilized to inhibit plant growth, while at a high pH, Fe availability becomes very low. However, different plant species show different adaptability to soil pH. Among cereal crops, rice is highly tolerant to Al but relatively sensitive to Fe-deficiency. By contrast, barley is the most sensitive to Al but highly tolerant to Fe-deficiency, while rye is able to adapt to a wide range of soil pHs. However, the molecular mechanisms underlying these differences are poorly understood. In this study, we conducted a comparative transcriptome analysis. Rice (WT, art1, star1), barley and rye were exposed to three different solutions (low pH with Al, moderate pH, or high pH with less Fe) for a short period, the roots were subjected to RNA-seq. The difference in gene expression in response to different pH were compared.

これまでにイネのカドミウム集積の品種間差を利用して、幾つかカドミウム集積に関与する新規QTLを検出している。そのうちの一つ、7番染色体に座乗するｑCd7についてファインマッピングを行い、候補遺伝子の絞込みに成功した。この遺伝子の発現をカドミウム集積量の異なる両親間で比較すると、差が認められなかった。またこの遺伝子はカドミウムによる誘導がなかった。両親間の配列を比較すると、1塩基の違いによる１アミノ酸の変化があった。しかし、酵母を用いたアッセイでは、両アリルともカドミウムに対する輸送活性を示した。両親のイネを用いて生理学的な解析も行った。その結果、カドミウム高集積品種では、マンガンによるカドミウムの抑制効果が見られたが、カドミウム低集積品種では、この抑制効果はほとんど見られなかった。これらの結果から、この1アミノ酸の変化はカドミウム輸送に対する親和性が低くなっている可能性があり、現在更なる解析を行っている。
ヒ素に関しては、ヒ素集積の異なる3種類のイネを用いて、関連遺伝子の発現量を比較した。その結果、ヒ素低集積品種のOsLsi1とOsLsi2の発現量が高集積品種より低いことが分かった。またケイ酸の吸収量も低くなっていた。これらのことはヒ素の低集積がケイ酸輸送体遺伝子の低発現に起因することを示唆している。

Nodes of graminaceous plants containing highly developed and fully organized vascular systems, which involved in “inter-vascular transfer” of mineral nutrients. In this study, we identified novel node localized mineral transporters for phosphorus, boron and iron in rice. Each transporter mediate inter-vascular transfer and contribute to preferential distribution control of each elements. In addition, we conducted promoter analysis of rice silicic acid channel Lsi6, which highly express in xylem transfer cells in enlarged vascular bundles in node. We estimate a regulatory promoter region for the tissue specific gene expression.

We identified novel genes involved in accumulation of cadmium (Cd) and arsenic (As) in rice. We found that OsNramp5 is a major transporter for Cd uptake in rice. OsNramp5 is polarly localized at the distal side of root exodermis and endodermis. Over-expression of OsHMA3, a tonoplast-localized Cd transporter, resulted in enhanced tolerance to Cd toxicity. Furthermore, we found that OsHMA2 localized at the node is involved in distribution of Cd to the grain. On the other hand, we found that OsABCC1 reduces As accumulation to the grain in rice. OsABCC1 is mainly localized to the tonoplast of phloem companion cells of the node.

We identified several rice genes involved in tolerance to Al toxicity, which is a major stress factor in acid soil. We also identified a cis-acting element of transcription factor ART1, which regulates the Al-tolerance genes in rice. Furthermore, we found that 1 kb insertion in the upstream of barley Al-tolerance gene, HvAACT1, increasing number of cis-acting elements of ART1 in the promoter region of Al-tolerance gene HlALMT1 in Yorkshire fog are important for enhanced expression of these genes. We also found that a node-based transporter OsNramp3 functions as switch in response to environmental change of Mn concentration. In addition, we have identified several genes involved in mineral element transport and constructed a mathematical model for Si uptake in rice.

We functionally characterized an ART-regulated gene, OsCDT3. OsCDT3 encodes a predicted peptide of 53 amino acid residues, of which 14(26. 4%) are cysteine residues. OsCDT3 was mainly expressed in the roots and its expression was specifically induced by Al exposure. OsCDT3 was localized to the plasma membrane. Knockdown of OsCDT3 resulted in increased sensitivity to Al in rice. Yeast expressing OsCDT3 showed increased tolerance to Al and decreased accumulation of Al. Our results indicate that OsCDT3 may play a role in detoxifying Al at the apoplast.

We identified several transporter genes involved in accumulation and detoxification of toxic metals including Cd, As and Al. TcHMA3 isolated from a Cd hyperaccumulator is required for tolerating high Cd and OsHMA3 from rice is involved in Cd accumulation in grain. We also found that Lsi1, a silicon influx transporter, is able to transport methylated arsenic(DMA and MMA). Furthermore, we have identified several novel transporter genes involved in Al tolerance in rice, Arabidopsis and buckwheat.

Expressions of many Al-tolerance genes are induced by ionic Al in rice. In this study, we found that a rice Al tolerance gene, STAR1, was regulated by a transcription factor, ART1 and further identified a cis-acting element recognized by ART1. We also produced transgenic rice over-expressing ART1. Although the transgenic lines showed increased expression level of ART1 and many downstream tolerance genes, the sensitivity to Al was enhanced compared to the wild type.

Silicon (Si) is a beneficial element for plant growth, which helps plants to overcome multiple stresses. In this project, we have identified several transporters involved in Si uptake and distribution. Lsi1 and Lsi2 identified from rice are expressed in the roots and polarly localized at the exodermis and endodermis. These transporters are important for Si uptake by the roots. Lsi6 is localized at the xylem parenchyma of leaf and node I and responsible for distribution of Si. We also identified similar transporters from maize and pumpkin. We found that they have different expression pattern and localization from rice.
