    Rhizoctonia solani is a basidiomycete phytopathogenic fungus that causes rapid necrosis in a wide range of crop species, leading to substantial agricultural losses worldwide. The species complex is divided into 13 anastomosis groups (AGs) based on hyphal fusion compatibility and further subdivided by culture morphology. While R. solani classifications were shown to be independent of host specificity, it remains unclear whether different R. solani isolates share similar virulence mechanisms. Here, we investigated the infectivity of Japanese R. solani isolates on Brachypodium distachyon and barley. Two isolates, AG-1 IA (from rice) and AG-4 HG-I+II (from cauliflower), infected leaves of both plants, but only AG-4 HG-I+II infected roots. B. distachyon accessions Bd3-1 and Gaz-4 and barley cultivar ‘Morex’ exhibited enhanced resistance to both isolates compared to B. distachyon Bd21 and barley cultivars ‘Haruna Nijo’ and ‘Golden Promise’. During AG-1 IA infection, but not AG-4 HG-I+II infection, resistant Bd3-1 and Morex induced genes for salicylic acid (SA) and N-hydroxypipecolic acid (NHP) biosynthesis. Pretreatment with SA or NHP conferred resistance to AG-1 IA, but not AG-4 HG-I+II, in susceptible B. distachyon Bd21 and barley Haruna Nijo. On the leaves of susceptible Bd21 and Haruna Nijo, AG-1 IA developed extensive mycelial networks with numerous infection cushions, which are specialized infection structures well-characterized in rice sheath blight. In contrast, AG-4 HG-I+II formed dispersed mycelial masses associated with underlying necrosis. We propose that the R. solani species complex encompasses at least two distinct infection strategies: AG-1 IA exhibits a hemibiotrophic lifestyle, while AG-4 HG-I+II follows a predominantly necrotrophic strategy.

    Abstract

    A diverse range of commensal bacteria inhabit the rhizosphere, influencing host plant growth and responses to biotic and abiotic stresses. While root-released nutrients can define soil microbial habitats, the bacterial factors involved in plant-microbe interactions are not well characterized. In this study, we investigated the colonization patterns of two plant disease biocontrol agents, Allorhizobium vitis VAR03-1 and Pseudomonas protegens Cab57, in the rhizosphere of Arabidopsis thaliana using Murashige and Skoog (MS) agar medium. VAR03-1 formed colonies even at a distance from the roots, preferentially in the upper part, while Cab57 colonized only the root surface. The addition of sucrose to the agar medium resulted in excessive proliferation of VAR03-1, similar to its pattern without sucrose, whereas Cab57 formed colonies only near the root surface. Overgrowth of both bacterial strains upon nutrient supplementation inhibited host growth, independent of plant immune responses. This inhibition was reduced in the VAR03-1 ΔrecA mutant, which exhibited increased biofilm formation, suggesting that some activities associated with the free-living lifestyle rather than the sessile lifestyle may be detrimental to host growth. VAR03-1 grew in liquid MS medium with sucrose alone, while Cab57 required both sucrose and organic acids. Supplementation of sugars and organic acids allowed both bacterial strains to grow near and away from Arabidopsis roots in MS agar. These results suggest that nutrient requirements for bacterial growth may determine their growth habitats in the rhizosphere, with nutrients released in root exudates potentially acting as a limiting factor in harnessing microbiota.

    Abstract

    Tailocins are headless phage tail structures that mediate interbacterial antagonism. Although the prototypical tailocins, R- and F-pyocins, in Pseudomonas aeruginosa, and other predominantly R-type tailocins have been studied, their presence in Alphaproteobacteria remains unexplored. Here, we report the first alphaproteobacterial F-type tailocin, named rhizoviticin, as a determinant of the biocontrol activity of Allorhizobium vitis VAR03-1 against crown gall. Rhizoviticin is encoded by a chimeric prophage genome, one providing transcriptional regulators and the other contributing to tail formation and cell lysis, but lacking head formation genes. The rhizoviticin genome retains a nearly intact early phage region containing an integrase remnant and replication-related genes critical for downstream gene transcription, suggesting an ongoing transition of this locus from a prophage to a tailocin-coding region. Rhizoviticin is responsible for the most antagonistic activity in VAR03-1 culture supernatant against pathogenic A. vitis strain, and rhizoviticin deficiency resulted in a significant reduction in the antitumorigenic activity in planta. We identified the rhizoviticin-coding locus in eight additional A. vitis strains from diverse geographical locations, highlighting a unique survival strategy of certain Rhizobiales bacteria in the rhizosphere. These findings advance our understanding of the evolutionary dynamics of tailocins and provide a scientific foundation for employing rhizoviticin-producing strains in plant disease control.

    Abstract

    Rhizoctonia solani AG‐1 IA causes a necrotrophic rice disease and is a serious threat to rice production. To date, only a few effectors have been characterized in AG‐1 IA. We previously identified RsIA_CtaG/Cox11 and showed that infiltration of the recombinant protein into rice leaves caused disease‐like symptoms. In the present study, we further characterized the functionality of RsIA_CtaG/Cox11. RsIA_CtaG/Cox11 is an alternative transcript of cytochrome c oxidase copper chaperone Cox11 that starts from the second AUG codon, but contains a functional secretion signal peptide. RNA interference with RsIA_CtaG/Cox11 reduced the pathogenicity of AG‐1 IA towards rice and Nicotiana benthamiana without affecting its fitness or mycelial morphology. Transient expression of the RsIA_CtaG/Cox11‐GFP fusion protein demonstrated the localization of RsIA_CtaG/Cox11 to mitochondria. Agro‐infiltration of RsIA_CtaG/Cox11 into N. benthamiana leaves inhibited cell death by BAX and INF1. In contrast to rice, agro‐infiltration of RsIA_CtaG/Cox11 did not induce cell death in N. benthamiana. However, cell death was observed when it was coinfiltrated with Os_CoxVIIa, which encodes a subunit of cytochrome c oxidase. Os_CoxVIIa appeared to interact with RsIA_CtaG/Cox11. The cell death triggered by coexpression of RsIA_CtaG/Cox11 and Os_CoxVIIa is independent of the leucine‐rich repeat receptor kinases BAK1/SOBIR1 and enhanced the susceptibility of N. benthamiana to AG‐1 IA. Two of the three evolutionarily conserved cysteine residues at positions 25 and 126 of RsIA_CtaG/Cox11 were essential for its immunosuppressive activity, but not for cell death induction. This report suggests that RsIA_CtaG/Cox11 appears to have a dual role in immunosuppression and cell death induction during pathogenesis.

    Abstract

    Pseudomonas syringae pv. tabaci 6605 (Pta6605) is a causal agent of wildfire disease in host tobacco plants. Although chemotaxis has been shown to be necessary for Pta6605 in tobacco infection, the chemoattractants at the site of infection are unclear. Pta6605 was attracted to the apoplastic fluid from not only host tobacco leaves but also non-host plant leaves, indicating that Pta6605 is attracted to common plant metabolites. Metabolome analysis of apoplastic fluid from tobacco leaves revealed that amino acids including γ-aminobutyric acid and organic acids are abundant, suggesting that these compounds are potential chemoattractants.

    <jats:p>Plants protect themselves from microorganisms by inducing pattern-triggered immunity (PTI) <jats:italic>via</jats:italic> recognizing microbe-associated molecular patterns (MAMPs), conserved across many microbes. Although the MAMP perception mechanism and initial events during PTI have been well-characterized, knowledge of the transcriptomic changes in plants, especially monocots, is limited during the intermediate and terminal stages of PTI. Here, we report a time-series high-resolution RNA-sequencing (RNA-seq) analysis during PTI in the leaf disks of <jats:italic>Brachypodium distachyon</jats:italic>. We identified 6,039 differentially expressed genes (DEGs) in leaves sampled at 0, 0.5, 1, 3, 6, and 12 hours after treatment (hat) with the bacterial flagellin peptide flg22. The k-means clustering method classified these DEGs into 10 clusters (6 upregulated and 4 downregulated). Based on the results, we selected 10 PTI marker genes in <jats:italic>B. distachyon</jats:italic>. Gene ontology (GO) analysis suggested a tradeoff between defense responses and photosynthesis during PTI. The data indicated the recovery of photosynthesis started at least at 12 hat. Over-representation analysis of transcription factor genes and cis-regulatory elements in DEG promoters implied the contribution of 12 WRKY transcription factors in plant defense at the early stage of PTI induction.</jats:p>

    Anastomosis group AG-1 IA of Rhizoctonia solani Khün has a wide host range and threatens crop production. Various glycosyltransferases secreted by phytopathogenic fungi play an essential role in pathogenicity. Previously, we identified a glycosyltransferase RsIA_GT (AG11A_09161) as a secreted protein-encoding gene of R. solani AG-1 IA, whose expression levels increased during infection in rice. In this study, we further characterized the virulence function of RsIA_GT. It is conserved not only in Basidiomycota, including multiple anastomosis groups of R. solani, but also in other primary fungal taxonomic categories. RsIA_GT possesses a signal peptide (SP) for protein secretion, and its functionality was proven using yeast and Nicotiana benthamiana. The SP-truncated form of RsIA_GT (RsIA_GT(ΔS)) expressed in Escherichia coli-induced lesion-like phenotype in rice leaves when applied to punched leaves. However, Agrobacterium-mediated transient expressions of both the full-length RsIA_GT and RsIA_GT(ΔS) did not induce cell death in N. benthamiana leaves. Instead, only RsIA_GT(ΔS) suppressed the cell death induced by two reference cell death factors BAX and INF1 in N.benthamiana. RsIA_GT(ΔS)R154A D168A D170A, a mutant RsIA_GT(ΔS) for the glycosyltransferase catalytic domain, still suppressed the BAX- or INF1-induced cell death, suggesting that the cell death suppression activity of RsIA_GT(ΔS) would be independent from its enzymatic activity. RsIA_GT(ΔS) also suppressed the H2O2 production and callose deposition and showed an effect on the induction of defense genes associated with the expression of BAX and INF1. The transient expression of RsIA_GT(ΔS) in N. benthamiana enhanced the lesion area caused by R. solani AG-1 IA. The secreted glycosyltransferase, RsIA_GT, of R. solani AG-1 IA is likely to have a dual role in virulence inside and outside of host cells.

    Pseudomonas syringae pv. tabaci 6605 (Pta6605) is a foliar plant pathogen that causes wildfire disease on tobacco plants. It requires chemotaxis to enter plants and establish infection. While chemotactic signals appear to be the main mechanism by which Pta6605 performs directional movement, the involvement of aerotaxis or energy taxis by this foliar pathogen is currently unknown. Based on domain structures and similarity with more than 50 previously identified putative methyl-accepting chemotaxis proteins (MCPs), the genome of Pta6605 encodes three potential aerotaxis transducers. We identified AerA as the main aerotaxis transducer and found that it possesses a taxis-to-serine-and-repellent (Tsr)-like domain structure that supports a periplasmic 4HB-type ligand-binding domain (LBD). The secondary aerotaxis transducer, AerB, possesses a cytosolic PAS-type LBD, similar to the Aer of Escherichia coli and Pseudomonas aeruginosa. Aerotaxis ability by single and double mutant strains of aerA and aerB was weaker than that by wild-type Pta6605. On the other hand, another cytosolic PAS-type LBD containing MCP did not make a major contribution to Pta6605 aerotaxis in our assay system. Furthermore, mutations in aerotaxis transducer genes did not affect surface motility or chemotactic attraction to yeast extract. Single and double mutant strains of aerA and aerB showed less colonization in the early stage of host plant infection and lower biofilm production than wild-type Pta6605. These results demonstrate the presence of aerotaxis transducers and their contribution to host plant infection by Pta6605.

    Rhizoctonia solani is a necrotrophic plant pathogen with a wide host range. R. solani is a species complex consisting of thirteen anastomosis groups (AGs) defined by compatibility of hyphal fusion reaction and subgroups based on cultural morphology. The relationship between such classifications and host specificity remains elusive. Here, we investigated the pathogenicity of seventeen R. solani isolates (AG-1 to 7) in Japan towards Arabidopsis thaliana using leaf and soil inoculations. The tested AGs, except AG-3 and AG-6, induced symptoms in both methods with variations in pathogenicity. The virulence levels differed even within the same AG and subgroup. Some isolates showed tissue-specific infection behavior. Thus, the AGs and their subgroups are suggested to be not enough to define the virulence (host and tissue specificity) of R. solani. We also evaluated the virulence of the isolates on Arabidopsis plants pretreated with salicylic acid, jasmonic acid, and ethylene. No obvious effects were detected on the symptom formation by the virulence isolates, but ethylene and salicylic acid slightly enhanced the susceptibility to the weak and nonvirulent isolates. R. solani seems to be able to overcome the induced defense by these phytohormones in the infection to Arabidopsis.

    <title>Abstract</title>Nonsteroidal anti-inflammatory drugs (NSAIDs), including salicylic acid (SA), target mammalian cyclooxygenases. In plants, SA is a defense hormone that regulates NON-EXPRESSOR OF PATHOGENESIS RELATED GENES 1 (NPR1), the master transcriptional regulator of immunity-related genes. We identify that the oxicam-type NSAIDs tenoxicam (TNX), meloxicam, and piroxicam, but not other types of NSAIDs, exhibit an inhibitory effect on immunity to bacteria and SA-dependent plant immune response. TNX treatment decreases NPR1 levels, independently from the proposed SA receptors NPR3 and NPR4. Instead, TNX induces oxidation of cytosolic redox status, which is also affected by SA and regulates NPR1 homeostasis. A cysteine labeling assay reveals that cysteine residues in NPR1 can be oxidized in vitro, leading to disulfide-bridged oligomerization of NPR1, but not in vivo regardless of SA or TNX treatment. Therefore, this study indicates that oxicam inhibits NPR1-mediated SA signaling without affecting the redox status of NPR1.

    Ralstonia syzygii subsp. indonesiensis (Rsi, former name: Ralstonia solanacearum phylotype IV) PW1001, a causal agent of potato wilt disease, induces hypersensitive response (HR) on its non-host eggplant (Solanum melongena cv. Senryo-nigou). The disaccharide trehalose is involved in abiotic and biotic stress tolerance in many organisms. We found that trehalose is required for eliciting HR on eggplant by plant pathogen Rsi PW1001. In R. solanacearum, it is known that the OtsA/OtsB pathway is the dominant trehalose synthesis pathway, and otsA and otsB encode trehalose-6-phosphate (T6P) synthase and T6P phosphatase, respectively. We generated otsA and otsB mutant strains and found that these mutant strains reduced the bacterial trehalose concentration and HR induction on eggplant leaves compared to wild-type. Trehalose functions intracellularly in Rsi PW1001 because addition of exogenous trehalose did not affect the HR level and ion leakage. Requirement of trehalose in HR induction is not common in R. solanacearum species complex because mutation of otsA in Ralstonia pseudosolanacearum (former name: Ralstonia solanacearum phylotype I) RS1002 did not affect HR on the leaves of its non-host tobacco and wild eggplant Solanum torvum. Further, we also found that each otsA and otsB mutant had reduced ability to grow in a medium containing NaCl and sucrose, indicating that trehalose also has an important role in osmotic stress tolerance.

    In plants, many of the enzymes in polyamine metabolism are encoded by multiple genes, whose expressions are differentially regulated under different physiological conditions. For comprehensive understanding of their regulation during the seedling growth stage, we examined the expression of polyamine metabolic genes in response to polyamines and stress-related plant hormones in Arabidopsis thaliana. While confirming previous findings such as induction of many of the genes by abscisic acid, induction of arginase genes and a copper amine oxidase gene, CuAOα3, by methyl jasmonate, that of an arginine decarboxylase gene, ADC2, and a spermine synthase gene, SPMS, by salicylic acid, and negative feedback regulation of thermospermine biosynthetic genes by thermospermine, our results showed that expressions of most of the genes are not responsive to exogenous polyamines. We thus examined expression of OsPAO6, which encodes an apoplastic polyamine oxidase and is strongly induced by polyamines in rice, by using the promoter-GUS fusion in transgenic Arabidopsis seedlings. The GUS activity was increased by treatment with methyl jasmonate but neither by polyamines nor by other plant hormones, suggesting a difference in the response to polyamines between Arabidopsis and rice. Our results provide a framework to study regulatory modules directing expression of each polyamine metabolic gene.

    Crown gall is a globally distributed and economically important disease of grapevine and other important crop plants. The causal agent of grapevine crown gall is tumorigenic Allorhizobium vitis (Ti) strains that harbor a tumor-inducing plasmid (pTi). The epidemic of grapevine crown gall has not been widely elucidated. In this study, we investigated the genetic diversity of 89 strains of Ti and nonpathogenic A. vitis to clarify their molecular epidemiology. Multi-locus sequence analysis (MLSA) of the partial nucleotide sequences of pyrG, recA, and rpoD was performed for molecular typing of A. vitis strains isolated from grapevines with crown gall symptoms grown in 30 different vineyards, five different countries, mainly in Japan, and seven genomic groups A to F were obtained. The results of MLSA and logistic regression indicated that the population of genetic group A was significantly related to a range of prefectures and that the epidemic of group A strains originated mainly in Hokkaido in Japan through soil infection. Moreover, group E strains could have been transported by infected nursery stocks. In conclusion, this study indicates that both soil infection and transporting of infected nursery stocks are working as infection source in Hokkaido.

    γ-Aminobutyric acid (GABA) is a widely distributed non-proteinogenic amino acid that accumulates in plants under biotic and abiotic stress conditions. Recent studies suggested that GABA also functions as an intracellular signaling molecule in plants and in signals mediating interactions between plants and phytopathogenic bacteria. However, the molecular mechanisms underlying GABA responses to bacterial pathogens remain unknown. In the present study, a GABA receptor, named McpG, was conserved in the highly motile plant-pathogenic bacteria Pseudomonas syringae pv. tabaci 6605 (Pta6605). We generated a deletion mutant of McpG to further investigate its involvement in GABA chemotaxis using quantitative capillary and qualitative plate assays. The wild-type strain of Pta6605 was attracted to GABA, while the ΔmcpG mutant abolished chemotaxis to 10‍ ‍mM GABA. However, ΔmcpG retained chemotaxis to proteinogenic amino acids and succinic semialdehyde, a structural analog of GABA. Furthermore, ΔmcpG was unable to effectively induce disease on host tobacco plants in three plant inoculation assays: flood, dip, and infiltration inoculations. These results revealed that the GABA sensing of Pta6605 is important for the interaction of Pta6605 with its host tobacco plant.

Sixty-one <italic>R. solani secretory effector-like protein</italic> genes (<italic>RsSEPGs</italic>) were identified using in silico approach with the publicly available gene annotation of <italic>R. solani</italic> AG-1 IA genome and our RNA-sequencing results obtained from hyphae grown on agar medium. Expression of <italic>RsSEPGs</italic> was analyzed at 6, 10, 16, 24, and 32 h after inoculation by a quantitative reverse transcription-polymerase chain reaction and 52 genes could be detected at least on a single time point tested.

The 23 <italic>RsSEPGs</italic> in the cluster 1–3 and 29 <italic>RsSEPGs</italic> in the cluster 4–6 are expected to be involved in biotrophic and necrotrophic interactions, respectively.

    Rhizoctonia solani is a soil-borne necrotrophic fungus that causes sheath blight in grasses. The basal resistance of compatible interactions between R. solani and rice is known to be modulated by some WRKY transcription factors (TFs). However, genes and defense responses involved in incompatible interaction with R. solani remain unexplored, because no such interactions are known in any host plants. Recently, we demonstrated that Bd3-1, an accession of the model grass Brachypodium distachyon, is resistant to R. solani and, upon inoculation with the fungus, undergoes rapid induction of genes responsive to the phytohormone salicylic acid (SA) that encode the WRKY TFs BdWRKY38 and BdWRKY44. Here, we show that endogenous SA and these WRKY TFs positively regulate this accession-specific R. solani resistance. In contrast to a susceptible accession (Bd21), the infection process in the resistant accessions Bd3-1 and Tek-3 was suppressed at early stages before the development of fungal biomass and infection machinery. A comparative transcriptome analysis during pathogen infection revealed that putative WRKY-dependent defense genes were induced faster in the resistant accessions than in Bd21. A gene regulatory network (GRN) analysis based on the transcriptome dataset demonstrated that BdWRKY38 was a GRN hub connected to many target genes specifically in resistant accessions, whereas BdWRKY44 was shared in the GRNs of all three accessions. Moreover, overexpression of BdWRKY38 increased R. solani resistance in Bd21. Our findings demonstrate that these resistant accessions can activate an incompatible host response to R. solani, and BdWRKY38 regulates this response by mediating SA signaling.

    OBJECTIVE: To gain insights into the virulence suppressive mechanism of a nonpathogenic strain of Rhizobium vitis ARK-1, we co-inoculated ARK-1 with a tumorigenic (Ti) strain of R. vitis to examine the expression of two essential virulence genes (virA and virG) and one non-essential gene (virD3) of the Ti strain at the wound site of grapevine. RESULTS: Co-inoculation of ARK-1 with a Ti strain VAT03-9 at a 1:1 cell ratio into grapevine shoots resulted in significantly lower expression of the virulence genes virA, virD3, and virG of VAT03-9 at 1 day after inoculation compared with those when shoots were inoculated only with VAT03-9. ARK-1 was not able to catabolize acetosyringone, which is the plant-derived metabolites inducing the entire vir regulon in Ti strains, suggesting the direct effect of ARK-1 on the induction of broad range of vir genes of R. vitis Ti strains.

  • Omeprazole enhances mechanical stress-induced root growth reduction in Arabidopsis thaliana Reviewed

    Mechanical sensing is one of the most fundamental processes for sessile plants to survive and grow. The response is known to involve calcium elevation in the cell. Arabidopsis seedlings grown horizontally on agar plates covered with a dialysis membrane show a 2-fold reduction in root growth compared with those grown vertically, a response to mechanical stress generated due to gravitropism of the root. To understand the molecular mechanism of how plant roots sense and respond to mechanical stimuli, we screened chemical libraries for compounds that affect the horizontal root growth in this experimental system and found that, while having no effect on root gravitropism, omeprazole known as a proton pump inhibitor significantly enhanced the mechanical stress-induced root growth reduction especially in lower pH media. In contrast, omeprazole reversed neither the alleviation of the mechanical stress-induced growth reduction caused by calcium depletion nor the insensitivity to the mechanical stress in the ethylene signaling mutant ein2. Together with the finding that omeprazole increased expression of touch-induced genes and ETHYLENE RESPONSE FACTOR1, our results suggest that the target of omeprazole mediates ethylene signaling in the root growth response to mechanical stress.

    <p>Chemical biology is an interdisciplinary scientific field covering chemistry and biology. It uses chemical-based molecules to reveal or control biological processes. Due to the nature and potential of chemicals, they provide an alternative way to identify novel genetic elements associated with redundancy or lethality. In addition, bioactive chemicals can be applied practically as pharmaceutical drugs or agrochemicals. In plant science, many biologically active small molecules were isolated so far from high-throughput screenings using libraries of diverse compounds and their successes demonstrated the usefulness and advantage of this approach. The use, experimental design, tips and future perspective of chemical screening procedures are described herein by sharing experiences based on the previous screening campaigns.</p>

    土壌に生息する糸状菌Rhizoctonia solaniは、世界規模で問題となっているコムギ・オオムギの根腐れ病の原因菌である。豪州での精力的な探索にも関わらず、本菌への抵抗性品種は確認されていない。我々は、岡山大学の大規模なオオムギ遺伝資源を用い、R. solani AG-4菌株に対する感染性評価を行った結果、Morex系統が強い抵抗性を示すことを発見した。 本研究では、その背景にある免疫応答の特徴づけ、および抵抗性遺伝子座の同定を目指す。 具体的には、罹病性と抵抗性のオオムギ系統で菌接種後のトランスクリプトームと転写ネットワーク解析を行い、その比較から抵抗性に寄与する免疫応答を明らかにする。また、オオムギ274系統の感染性を定量評価し、ゲノムワイド関連解析(GWAS)で抵抗性遺伝子座を特定する。
    本年度は、研究代表者の異動によりオオムギおよびR. solaniの育成・実験系の立ち上げを再度実施し、オオムギ芽生えへのR. solani接種方法と表現型解析方法の構築を進めた。芽生えへの菌糸懸濁液の灌注接種と菌を混入・培養した汚染土壌を用いた接種を検討し、後者が比較的安定して病徴を誘導できることがわかった。しかし、罹病性を示す系統であるはるな二条においても、菌接種によって枯死に至るほどの強い生育抑制は観察されなかった。一方、菌接種によって有意に影響を受ける表現型として草丈と根長を見出し、抵抗性を示すMorexとの間で病徴の程度に差がみられる時点を明らかにした。

    紋枯病は植物病原糸状菌Rhizoctonia solaniが引き起こすイネなどの主要病害である。本菌は宿主範囲が広く、他の様々な作物種においても収量や品質を悪化させる。病害防除には原因菌の感染生理の理解が不可欠だが、本菌の研究は進んでいない。本菌は感染後早い段階で壊死を引き起こすことから殺生菌に分類されており、宿主細胞を殺して栄養を摂取すると考えられてきた。しかし、我々はモデル単子葉植物であるミナトカモジグサを用いた研究から、本菌が感染初期に生きた宿主から栄養を摂取する活物寄生段階を経るという状況証拠を得た。本年は双子葉植物のモデルであるシロイヌナズナを用い、本菌の感染様式が他の植物種においても共通の事象であるか否かを検証した。まず日本国内から分離された17種類のR. solani菌株(13種類存在する菌糸融合群のうち7種類を含む)について、シロイヌナズナの切葉への接種および菌汚染土壌への移植接種を行い、感染性の有無について調べた。地上部と地下部の両方に感染性を示したものは6種類存在し、地上部のみに感染性を示したものは3種類、地下部のみに感染性を示したものは2種類であった。これらの感染性の有無と菌糸融合群や分離源との相関性はなかった。特定の宿主から分離される菌糸融合群が同一であることから、宿主特異性との関連が想定されてきたが、病原性は個々の菌株の性質に依存することが示された。次に、植物の免疫関連ホルモンであるサリチル酸、ジャスモン酸、エチレンを事前処理したシロイヌナズナに各菌株を接種し、誘導抵抗性の効果を調べた。その結果、いずれの植物ホルモン処理でも病原性株の感染性は変化しなかった。これはミナトカモジグサでサリチル酸が抵抗性を誘導する結果とは異なっていた。本菌はシロイヌナズナでは活物寄生段階が極めて短いか、植物種によって異なる感染プロセスを経る可能性が示された。

    植物は多くの微生物が共通に持つ物質を感知して自然免疫を誘導する。一方、自然界には植物の表面や内部に住み着く微生物が存在する。これらの微生物は宿主免疫を回避すると想像されるがその仕組みはわかっていない。本研究ではブドウ根圏に定着する根頭がんしゅ病菌Rhizobium vitis Ti株、その病気を拮抗する同属同種のVAR03-1株、非病原性非拮抗性のVAR06-30株、およびモデル植物シロイヌナズナを材料とし、片利共生細菌の植物根圏への定着機構を明らかにする。昨年までにこれら菌株を混合した寒天培地でシロイヌナズナを生育させた場合、根の周辺に細菌コロニーが形成されること、および培地にショ糖を添加すると植物の成長が著しく抑制されることを明らかにした。この結果から、細菌は炭素源を求めて植物への寄生(共生)を行うが、炭素源の存在によりそのプログラムが破綻したと予想し、ショ糖存在下でシロイヌナズナの生育を阻害しなくなるVAR03-1株の変異体を探索した。3変異株が得られ、原因遺伝子はTCA回路に関わるpycA、ビタミンB12生合成に関わるcobJ、膜脂質の生合成に関わるmprFで、いずれも生体維持機能の低下が予想された。これと一致して、各変位菌株はMS液体培地中での増殖速度が低かった。しかし、投入する菌体量を1/10にしても植物の生育阻害の程度が変わらないこと、変異菌株が植物周辺にコロニーを形成していたことから、増殖量ではなく共生行動の減退が原因と推察した。ショ糖存在下で矮小化した植物は防御応答を発現しておらず、矮小化は過剰な防御応答ではなく菌の過剰感染が原因と推測された。R. vitisの植物への定着能は、ショ糖により植物の生育を阻害するほどまでに活性化し、各変異体のように生体維持機能が低下すると、定着に割くエネルギーが欠如し、定着行為が低下して生育阻害効果が低減したと推測した。

    The filamentous fungus Rhizoctonia solani causes sheath blight, an important disease of rice. Its infection strategy remains unclear. In this study, we analyzed the expression of the small secretory protein (so-called effector) encoding genes of Rhizoctonia solani during the infection process in a model pathosystem developed using Brachypodium distachyon, an experimental monocotyledonous plant. As a result, we confirmed that the fungus uses them in the early infection stage before necrosis induction. In contrast to conventional recognition, it was suggested that the fungus undergoes a biotrophic stage of suppressing plant immunity before killing the host.

    Crown gall of grapevine, which is caused by tumorigenic Rhizobium vitis (Ti), is the most important bacterial disease of grapevine throughout the world. Previously, we discovered that nonpathogenic R. vitis strain VAR03-1 and ARK-1 were a biocontrol agent that suppress grapevine crown gall disease caused by a Ti strain. The objective of this study is to provide insights into the mechanism of biocontrol for grapevine crown gall by VAR03-1 and ARK-1. Both strains were able to strongly suppress several virulence genes expression of Ti. In the case of strain VAR03-1, also, both the expression of the virulence gene and growth of Ti were suppressed in vitro when it was cultivated in the VAR03-1 culture filtrate. Both activities were detected in the >100,000 molecular weight fraction of the filtrate. Our results suggest that the antagonistic effects of VAR03-1 on Ti are mediated by huge particle(s) consisting of multiple proteins released in the culture media.

    Sheath blight, caused by the soil-born fungus Rhizoctonia solani, is a major disease of rice. We previously identified sheath blight-resistant natural accessions of the small grass plant Brachypodium distachyon. In this study, we characterized these accessions and searched for the candidate genes that confer sheath blight resistance. A sheath blight-resistant accession, Bd3-1, suppressed the infection process of R. solani and activated salicylic acid-dependent immunity at an early stage of infection. Moreover, we identified eight candidate genes that might confer sheath blight resistance based on the QTL analysis using recombinant inbred lines between Bd3-1 and a sheath-blight susceptible accession, Bd21.

    Plant defense activator confers disease resistance in plants by activating immune response. A phytohormone salicylic acid (SA) controls defense response and it is inactivated by glucosylation by an enzyme glucosyltransferase (SAGT). Since inhibition of SAGT enhanced plant immune response, we look for novel SAGT inhibitors as a lead compound for practical agrochemical. From the screening of over 200,000 diverse organic molecules supplied by Drug Discovery Initiative of University of Tokyo, we successfully identified 12 compounds which strongly inhibited Arabidopsis SAGT. They actually upregulated immune response of Arabidopsis suspension culture. Their activities on plants and inhibition constants are being analyzed. Their potentials as agrochemical will be evaluated in the crop field in collaboration with companies.

    Salicylic acid(SA) is a plytohormone which regulates immunity responses but its perception mechanism is still unclear. In this study, SA receptor was explored using Imprimatin C1, an SA analog. Imprimatin C1 seems to be converted to 4-chlorobenzoic acid inside plants. It mimic only SA function for downstream signaling, suggesting its function as partial agonist of SA. We isolated Imprimatin C1 insensitive Arabidopsis mutants and revealed that three of them expressed defense genes constitutively. They are expected to have mutations in SA receptor.

    Conditional phenotypes are mutant phenotypes which can be detected under some stress treatment or environmental conditions. We developed a high throughput assay system to detect the conditional phenotypes for many tagging lines quickly using multi-titer plates. According to image scanning, we could calculate the green parts of each well that is indicating the growth status. By this detection system, we could find a novel ABA hypersensitive mutant.

    NSAIDターゲットの生化学的手法による単離・精製 NSAIDがLOXを標的としているという仮説が本研究はよって否定されることも想定し、NSAIDおよびSAの標的をマイクロビーズ担体を使用したアフィニティ精製によって単離するという別のアプローチを平行して実施した。東工大の半田先生らにより開発されたSGビーズ担体はミラクルビーズとも呼ばれ多くの実績がある(倉森ら、ケミカルバイオロジーケミカルゲノミクス、Springer、半田編、3-14)。化合物をそのアミノ基を介してSGビーズに固定し、培養細胞タンパク質抽出液を用いてアフィニティ精製し、溶出タンパク質を質量分析計で直接同定した。質量分析は理研プロテオームプラットフォームを利用した。SAの活性アナログであるBTHやINAなどはSA合成不全変異体においても抵抗性関連遺伝子発現活性を発揮することからそのターゲット分子はSA増幅経路以外であることを示しており、これはSAの標的分子が複数存在することを示している。従ってSA自体を基質とした場合には標的候補タンパク質が複数個得られる可能性があり、これは別の発見となる。SAを基質としたアフィニティ精製によるタンパク質分離はKlessigらにより行われているもののSAの効果を説明するには至っていない(Du and Klessig, Plant Physiol (1997) 113;1319-27)。SGビーズは従来の担体と比較して飛躍的に性能が向上していることと、近年の質量分析技術の発展により、新規結合タンパク質(受容体)の同定が期待できる。
    NSAIDターゲットの遺伝学的手法による単離 NSAIDおよびSAの標的タンパク質が量的に少ない、あるいは結合が弱い場合、生化学的単離は困難である。この場合に備えてNSAIDおよびSAの標的を遺伝学的手法により単離した。具体的にはJAによって誘導されるVSP遺伝子のプロモーターをつないだルシフェレースマーカーをもつシロイヌナズナの遺伝子組換体に変異をかけたプールからNSAIDおよびSAによっても発現が減少しない変異体を単離した。

    Ds端配列データベースを利用して、slh1のDs挿入遺伝子のノックアウトalleleを2ライン単離できたが、これらは生育阻害を示さなかった。また、cDNA導入によって表現型が相補されなかったことから、Ds挿入はslh1の原因遺伝子でないことが判明した。そこで、ポジショナルクローニングを行った。その結果、slh1は、Dsを含む83.6kbp内にマッピングされ、これはDsのハイグロマイシン耐性と表現型の強い連鎖と一致していた。領域内の塩基配列解析により、青枯病菌Ralstonia solanasearumへの耐性を与えるRRS1-R遺伝子のWRKYドメイン内に3塩基(TTA)の挿入変異を発見した。RRS1-Rは典型的なR-geneにWRKYドメインが融合した遺伝子で、塩基挿入はDs転移の際に生じたフットプリントと考えられるが、この変異によってWRKYの保存領域にロイシンの挿入が起こり、DNA結合能の喪失が予想された。現在相補性試験を行っている。slh1表現型はNahGの導入によって相補されず、病原体抵抗性遺伝子発現の抑圧も確認されなかった。またnpr1-5との二重破壊株の解析においても、表現型が抑圧されなかったことから、slh1は、サリチル酸とNPR1に非依存的な経路が活性化している事がわかった。湿度低下における気孔閉鎖とABA誘導性遺伝子の発現は正常であった。
    本研究課題の遂行により、slh1はサリチル酸とNPR1に非依存的な経路を介した細胞死と病原体抵抗性反応を自発的に引き起こす劣勢の変異体であり、その活性化は高湿度条件によって抑制されるということが明かとなった。原因はRRS1-R遺伝子のWRKYドメインの機能喪失によるものと考えられ、これはこれまで知見の乏しい「R-geneによる抵抗性反応制御メカニズム」の新たな発見となる。相補実験が終了し次第発表を予定している。
