    Some plants have massive sex-linked regions. To test hypotheses about their evolution, we sequenced the genome of Silene latifolia , in which giant heteromorphic sex chromosomes were first discovered in 1923. It has long been known that the Y chromosome consists mainly of a male-specific region that does not recombine with the X chromosome and carries the sex-determining genes and genes with other male functions. However, only with a whole Y chromosome assembly can candidate genes be validated experimentally and their locations determined and related to the suppression of recombination. We describe the genomic changes as the ancestral chromosome evolved into the current XY pair, testing ideas about the evolution of large nonrecombining regions and the mechanisms that created the present recombination pattern.

    Abstract

    The awn is a bristle-like extension from the tip of the lemma in grasses. In barley, the predominant cultivars possess long awns that contribute to grain yield and quality through photosynthesis. In addition, various awn morphological mutants are available in barley, rendering it a useful cereal crop to investigate the mechanims of awn development. Here, we identified the gene causative of the short and crooked awn (sca) mutant, which exhibits a short and curved awn phenotype. Intercrossing experiments revealed that the sca mutant induced in the Japanese cultivar (cv.) “Akashinriki” is allelic to the independently isolated moderately short-awn mutant breviaristatum-a (ari-a). Map-based cloning and sequencing revealed that SCA encodes the Polycomb group–associated protein EMBRYONIC FLOWER 1. We found that SCA affects awn development through the promotion of cell proliferation, elongation, and cell wall synthesis. RNA sequencing of cv. Bowman backcross-derived near-isogenic lines of sca and ari-a6 alleles showed that SCA is directly or indirectly involved in promoting the expression of genes related to awn development. Additionally, SCA represses various transcription factors essential for floral organ development and plant architecture, such as MADS-box and Knotted1-like homeobox genes. Notably, the repression of the C-class MADS-box gene HvMADS58 by SCA in awns is associated with the accumulation of the repressive histone modification H3K27me3. These findings highlight the potential role of SCA-mediated gene regulation, including histone modification, as a novel pathway in barley awn development.

    Proteins in the importin α (IMPA) family play pivotal roles in intracellular nucleocytoplasmic transport. Arabidopsis thaliana possesses nine IMPA members, with diverse tissue-specific expression patterns. Among these nine IMPAs, IMPA1, IMPA2, and IMPA4 cluster together phylogenetically, suggesting potential functional redundancy. To explore this redundancy, we analyzed single and multiple T-DNA mutants for these genes and discovered severe growth defects in the impa1 impa2 impa4 triple knockout mutant but not in the single or double mutants. Complementation with IMPA1, IMPA2, or IMPA4 fused to green fluorescent protein (GFP) rescued the growth defects observed in the impa1 impa2 impa4 mutant, indicating the functional redundancy of these three IMPAs. The IMPA-GFP fusion proteins were localized in the nucleus and nuclear envelope, suggesting their involvement in nucleocytoplasmic transport processes. Comparative transcriptomics revealed that salicylic acid (SA)-responsive genes were significantly upregulated in the impa1 impa2 impa4 triple mutant. Consistent with this observation, impa1 impa2 impa4 mutant plants accumulated SA and reactive oxygen species to high levels compared with wild-type plants. We also found enhanced resistance to the anthracnose pathogen Colletotrichum higginsianum in the impa1 impa2 impa4 mutants, suggesting that defense responses were constitutively activated in the impa1 impa2 impa4 mutant. Our findings shed light on the redundant roles of IMPA1, IMPA2, and IMPA4 in suppressing the autoimmune responses and suggest avenues of research to clarify their potentially unique roles.

    In flowering plants, different lineages have independently transitioned from the ancestral hermaphroditic state into and out of various sexual systems1. Polyploidizations are often associated with this plasticity in sexual systems2,3. Persimmons (the genus Diospyros) have evolved dioecy via lineage-specific palaeoploidizations. More recently, hexaploid D. kaki has established monoecy and also exhibits reversions from male to hermaphrodite flowers in response to natural environmental signals (natural hermaphroditism, NH), or to artificial cytokinin treatment (artificial hermaphroditism, AH). We sought to identify the molecular pathways underlying these polyploid-specific reversions to hermaphroditism. Co-expression network analyses identified regulatory pathways specific to NH or AH transitions. Surprisingly, the two pathways appeared to be antagonistic, with abscisic acid and cytokinin signalling for NH and AH, respectively. Among the genes common to both pathways leading to hermaphroditic flowers, we identified a small-Myb RADIALIS-like gene, named DkRAD, which is specifically activated in hexaploid D. kaki. Consistently, ectopic overexpression of DkRAD in two model plants resulted in hypergrowth of the gynoecium. These results suggest that production of hermaphrodite flowers via polyploidization depends on DkRAD activation, which is not associated with a loss-of-function within the existing sex determination pathway, but rather represents a new path to (or reinvention of) hermaphroditism.

    Transposable elements are present in a wide variety of organisms; however, our understanding of the diversity of mechanisms involved in their activation is incomplete. In this study, we analyzed the transcriptional activation of the ONSEN retrotransposon, which is activated by high-temperature stress in Arabidopsis thaliana. We found that its transcription is significantly higher in the Japanese ecotype Kyoto. Considering that transposons are epigenetically regulated, DNA methylation levels were analyzed, revealing that CHH methylation was reduced in Kyoto compared to the standard ecotype, Col-0. A mutation was also detected in the Kyoto CMT2 gene, encoding a CHH methyltransferase, suggesting that it may be responsible for increased expression of ONSEN. CHH methylation is controlled by histone modifications through a self-reinforcing loop between DNA methyltransferase and histone methyltransferase. Analysis of these modifications revealed that the level of H3K9me2, a repressive histone marker for gene expression, was lower in Kyoto than in Col-0. The level of another repressive histone marker, H3K27me1, was decreased in Kyoto; however, it was not impacted in a Col-0 cmt2 mutant. Therefore, in addition to the CMT2 mutation, other factors may reduce repressive histone modifications in Kyoto.

    BACKGROUND: Polyploidy provides new genetic material that facilitates evolutionary novelty, species adaptation, and crop domestication. Polyploidy often leads to an increase in cell or organism size, which may affect transcript abundance or transcriptome size, but the relationship between polyploidy and transcriptome changes remains poorly understood. Plant cells often undergo endoreduplication, confounding the polyploid effect. RESULTS: To mitigate these effects, we select female gametic cells that are developmentally stable and void of endoreduplication. Using single-cell RNA sequencing (scRNA-seq) in Arabidopsis thaliana tetraploid lines and isogenic diploids, we show that transcriptome abundance doubles in the egg cell and increases approximately 1.6-fold in the central cell, consistent with cell size changes. In the central cell of tetraploid plants, DEMETER (DME) is upregulated, which can activate PRC2 family members FIS2 and MEA, and may suppress the expression of other genes. Upregulation of cell size regulators in tetraploids, including TOR and OSR2, may increase the size of reproductive cells. In diploids, the order of transcriptome abundance is central cell, synergid cell, and egg cell, consistent with their cell size variation. Remarkably, we uncover new sets of female gametophytic cell-specific transcripts with predicted biological roles; the most abundant transcripts encode families of cysteine-rich peptides, implying roles in cell-cell recognition during double fertilization. CONCLUSIONS: Transcriptome in single cells doubles in tetraploid plants compared to diploid, while the degree of change and relationship to the cell size depends on cell types. These scRNA-seq resources are free of cross-contamination and are uniquely valuable for advancing plant hybridization, reproductive biology, and polyploid genomics.

    Insect galls are unique organs that provide shelter and nutrients to the gall-inducing insects. Although insect galls are fascinating structures for their unique shapes and functions, the process by which gall-inducing insects induce such complex structures is not well understood. Here, we performed RNA-sequencing-based comparative transcriptomic analysis of the early developmental stage of horned gall to elucidate the early gall-inducing process carried out by the aphid, Schlechtendalia chinensis, in the Chinese sumac, Rhus javanica. There was no clear similarity in the global gene expression profiles between the gall tissue and other tissues, and the expression profiles of various biological categories such as phytohormone metabolism and signaling, stress-response pathways, secondary metabolic pathways, photosynthetic reaction, and floral organ development were dramatically altered. Particularly, master transcription factors that regulate meristem, flower, and fruit development, and biotic and abiotic stress-responsive genes were highly upregulated, whereas the expression of genes related to photosynthesis strongly decreased in the early stage of the gall development. In addition, we found that the expression of class-1 KNOX genes, whose ectopic overexpression is known to lead to the formation of de novo meristematic structures in leaf, was increased in the early development stage of gall tissue. These results strengthen the hypothesis that gall-inducing insects convert source tissues into fruit-like sink tissues by regulating the gene expression of host plants and demonstrate that such manipulation begins from the initial process of gall induction.

    Agronomically important traits often develop during the later stages of crop growth as consequences of various plant-environment interactions. Therefore, the temporal physiological states that change and accumulate during the crop's life course can significantly affect the eventual phenotypic differences in agronomic traits among crop varieties. Thus, to improve productivity, it is important to elucidate the associations between temporal physiological responses during the growth of different crop varieties and their agronomic traits. However, data representing the dynamics and diversity of physiological states in plants grown under field conditions is sparse. In this study, we quantified the endogenous levels of five phytohormones-auxin, cytokinins, abscisic acid, jasmonate, and salicylic acid-in the leaves of eight diverse barley (Hordeum vulgare) accessions grown under field conditions sampled weekly over their life course to assess the ongoing fluctuations in hormone levels in the different accessions under field growth conditions. Notably, we observed enormous changes over time in the development-related plant hormones, such as auxin and cytokinins. Using 3' RNA-seq-based transcriptome data from the same samples, we investigated the expression of barley genes orthologous to known hormone-related genes of Arabidopsis throughout the life course. These data illustrated the dynamics and diversity of the physiological states of these field-grown barley accessions. Together our findings provide new insights into plant-environment interaction, highlighting that there is cultivar diversity in physiological responses during growth under field conditions.

    Regulation of the stability and the quality of mitochondrial RNA is essential for the maintenance of mitochondrial and cellular functions in eukaryotes. We have previously reported that the eukaryotic poly(A)-specific ribonuclease (PARN) and the prokaryotic poly(A) polymerase encoded by AHG2 and AGS1, respectively, coordinately regulate the poly(A) status and the stability of mitochondrial mRNA in Arabidopsis. Mitochondrial function of PARN has not been reported in any other eukaryotes. To know how much this PARN-based mitochondrial mRNA regulation is conserved among plants, we studied the AHG2 and AGS1 counterparts of the liverwort, Marchantia polymorpha, a member of basal land plant lineage. We found that M. polymorpha has one ortholog each for AHG2 and AGS1, named MpAHG2 and MpAGS1, respectively. Their Citrine-fused proteins were detected in mitochondria of the liverwort. Molecular genetic analysis showed that MpAHG2 is essential and functionally interacts with MpAGS1 as observed in Arabidopsis. A recombinant MpAHG2 protein had a deadenylase activity in vitro. Overexpression of MpAGS1 and the reduced expression of MpAHG2 caused an accumulation of polyadenylated Mpcox1 mRNA. Furthermore, MpAHG2 suppressed Arabidopsis ahg2-1 mutant phenotype. These results suggest that the PARN-based mitochondrial mRNA regulatory system is conserved in land plants.

    The evolution of land flora transformed the terrestrial environment. Land plants evolved from an ancestral charophycean alga from which they inherited developmental, biochemical, and cell biological attributes. Additional biochemical and physiological adaptations to land, and a life cycle with an alternation between multicellular haploid and diploid generations that facilitated efficient dispersal of desiccation tolerant spores, evolved in the ancestral land plant. We analyzed the genome of the liverwort Marchantia polymorpha, a member of a basal land plant lineage. Relative to charophycean algae, land plant genomes are characterized by genes encoding novel biochemical pathways, new phytohormone signaling pathways (notably auxin), expanded repertoires of signaling pathways, and increased diversity in some transcription factor families. Compared with other sequenced land plants, M. polymorpha exhibits low genetic redundancy in most regulatory pathways, with this portion of its genome resembling that predicted for the ancestral land plant.

    植物の性決定機構の変化を介した繁殖戦略の構築メカニズムや、雌雄のゲノムの制御には、エピゲノム制御が重要な役割を果たしていることが知られている。エピゲノム修飾の中でも、シトシンのメチル化は遺伝子やトランスポゾンの発現に影響を与える。性決定関連因子やインプリント遺伝子なども、トランスポゾンの挿入がトリガーとなって構築されたと考えられており、繁殖戦略の進化と、エピゲノム制御及びトランスポゾン転移は密接な関係がある。
    申請者らは、DNAメチル化などの植物のエピゲノム制御機構がどのように進化してきたかを明らかにするため、進化上、陸上植物の基部に位置するゼニゴケを用い解析を進めた。これまでに、ゼニゴケは被子植物で明らかになったDNAメチル化の制御機構との共通点だけでなく、動物と似たDNAメチル化制御システムの特徴を複数有することが明らかになってきた。また、最近の報告から、ゼニゴケでは、これまで被子植物で知られている報告とは異なり、DNAメチル化だけでなく、ヒストンH3K27me3の修飾がトランスポゾン領域に局在しており、発現の抑制に関わることが示唆されている。これらを踏まえ、ゼニゴケにおけるDNAメチル化とH3K27me3などのヒストンによるトランスポゾン制御の多層的な制御の全体像を明らかにすることを目的として、DNAメチル化に関与する変異体を用いてDNAメチル化とトランズポゾンの制御について解析するとともに、DNAメチル化とヒストン修飾の相互作用についても解析を行った。

    DNAメチル化は'非ゲノム情報'のうち唯一世代を超えて安定的に伝わることが証明されている修飾であり、クロマチンとの相互作用を介して遺伝子の発現制御に関わることが知られている。DNAメチル化の次世代への伝達機構については、動物と植物の間で違いがみられ、動物では生殖系列でDNAメチル化がリプログラミングされ、雌雄のゲノムの差が生じる一方、被子植物では減数分裂後、胚乳系列でのみDNAメチル化が解除され、卵及び精細胞ではDNAメチル化が維持される。そのため植物ではDNAメチル化の変化が次の世代に伝わりうるとされている。
    そこで、植物特有のDNAメチル化維持機構がどのように進化してきたかを明らかにするため、本研究では、進化上、陸上植物の基部に位置するゼニゴケを用い解析を進めた。これまでに、我々の解析により、ゼニゴケにおけるDNAメチル化制御機構は被子植物と共通した特徴だけでなく、異なる制御の特徴を持つことを示唆する結果が得られている。本研究では特に、ゼニゴケの減数分裂前後におけるDNAメチル化の制御機構に焦点を当て、解析を行った。
    今年度は、ゼニゴケのDNAメチル化の詳細な解析を進めるための育成環境や生殖器の誘導条件など、実験に必要な材料の準備を行った。環境が整い、サンプリングの技術等の条件が整い、次世代シーケンサを用いたゲノムワイドバイサルファイト解析を行う状況が整った。また、ゼニゴケにおいてDNAメチル化に関与する因子の変異体を作成し、詳細な機能解析を進めている。
