In meristems, where new plant organs initiate, the cell proliferation potential depends on stem cell regulators, but the mechanisms linking their local activity with the cell cycle machinery remain unknown. Here we show a positional gradient of G1 duration in the Arabidopsis root meristem spanning from ~2 h near the meristem boundary to more than 20 h in the early stem cell derivatives. Mutations in the stem cell regulatory PLETHORA (PLT) genes and the cell cycle RETINOBLASTOMA-RELATED 1 gene shortened G1 duration, abolishing the G1 duration gradient, whereas PLT2 overexpression increased G1 duration. Data-driven computer modelling supported the presence of an incoherent feed-forward loop. We found that PLT genes are drivers with simultaneous and opposing roles in maintaining stem cell activity and inhibiting G1 progression through a cascade involving the CDK inhibitor KRP5, a PLT target and RETINOBLASTOMA-RELATED 1. The G1 duration gradient is developmentally regulated and established after the emergence of lateral roots from the primary root and correlates with increased tolerance to genome damage. Our study establishes a previously undescribed proximal-distal G1 duration gradient during root development that is shaped by the balanced activity of stem cell maintenance and cell cycle regulators.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"38 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145083348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we constructed a single-cell chromatin accessibility atlas for Oryza sativa from 103,911 nuclei representing 126 cell states across nine organs. Comparative genomics between O. sativa and 57,552 nuclei from four additional grass species (Zea mays, Sorghum bicolor, Panicum miliaceum and Urochloa fusca) revealed that chromatin accessibility conservation varies with cell-type specificity. Epidermal accessible chromatin regions in the leaf were less conserved compared to other cell types, indicating accelerated regulatory evolution in the L1-derived epidermal layer of O. sativa relative to other species. Conserved accessible chromatin regions overlapping the repressive histone modification H3K27me3 were identified as potentially silencer-like CREs, as deleting these regions led to up-regulation of gene expression. This study provides a comprehensive epigenomic resource for the rice community, demonstrating the utility of a comparative genomics approach that highlights the dynamics of plant cell-type-specific CRE evolution.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"8 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While apoplastic effectors have major roles in pathogenicity, whether and how they directly attack extracellular immune receptors remains unclear. Here we identify an apoplastic effector FgLPMO9A from the fungal pathogen Fusarium graminearum that directly inhibits maize immune receptor ZmLecRK1-mediated resistance. FgLPMO9A belongs to the polysaccharide monooxygenase family, which depolymerizes polysaccharides. Deletion of FgLPMO9A attenuates F. graminearum virulence on maize, but this defect is fully rescued in the zmlecrk1 mutants. FgLPMO9A interacts with the extracellular S-domain of ZmLecRK1 and disrupts N-glycosylation at the N341 site, thereby promoting ZmLecRK1 degradation via the NBR1-mediated autophagy pathway. Notably, the ZmLecRK1 variant with the N341Q substitution confers enhanced resistance to F. graminearum in maize. We demonstrate that F. graminearum dampens maize immunity by deploying an apoplastic effector to induce extracellular immune receptor degradation.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"17 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In principle, epigenetic information inherited independently of DNA sequence can also enable evolution, but whether this occurs in natural populations is unknown. Here we show that single-nucleotide and epigenetic gene body DNA methylation (gbM) polymorphisms explain comparable amounts of expression variance in Arabidopsis thaliana populations. We genetically demonstrate that gbM regulates transcription, and we identify and genetically validate many associations between gbM polymorphism and the variation of complex traits: fitness under heat and drought, flowering time and accumulation of diverse minerals. Epigenome-wide association studies pinpoint trait-relevant genes with greater precision than genetic association analyses, probably due to reduced linkage disequilibrium between gbM variants. Finally, we identify numerous associations between gbM epialleles and diverse environmental conditions in native habitats, suggesting that gbM facilitates adaptation. Overall, our results indicate that epigenetic methylation variation fundamentally shapes phenotypic diversity in a natural population.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"16 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aminotransferases are core enzymes of the nitrogen metabolic network for synthesizing various organonitrogen compounds. Although each aminotransferase can potentially catalyse hundreds of transamination reactions with different combinations of amino and keto acid substrates, the full functionality of many aminotransferases remains elusive. Here we employed high-throughput gene synthesis and enzyme assay platforms to determine the substrate specificities of 38 aminotransferases of Arabidopsis thaliana and unveiled many previously unrecognized activities among a total of 4,104 reactions tested. The integration of these biochemical data in an enzyme-constrained metabolic model of Arabidopsis and in silico simulation further revealed that the promiscuity of aminotransferases may alter nitrogen distribution profiles and contribute to the robustness of the nitrogen metabolic network. This study provides foundational knowledge for deciphering the plant nitrogen metabolic network and improving nitrogen use efficiency in crops. Systematic characterization of Arabidopsis aminotransferase family enzymes uncovered many previously unrecognized activities and revealed their multi-substrate specificity, aspects that probably contribute to the robustness of the nitrogen metabolic network.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 9","pages":"1863-1876"},"PeriodicalIF":13.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
