However, the emanating root triggers in these scenarios remain elusive. Here we identify an N-hydroxypipecolic-acid-(NHP-)directed, salicylic-acid-related mechanism of root-triggered systemic resistance in Arabidopsis, which uses components of systemic acquired resistance known in leaves. However, in contrast to the inductive nature of systemic acquired resistance, FLAVIN-DEPENDENT MONOOXYGENASE 1 (FMO1) continuously synthesizes NHP in roots, while the glucosyltransferase UGT76B1 concomitantly conjugates and immobilizes NHP. Physical grafting experiments and tissue-specific knockouts revealed that the loss of UGT76B1 in roots leads to enhanced NHP release, initiating shoot responses. This counteracting standby FMO1/UGT76B1 circuit is specifically and sensitively modulated by root-associated microorganisms. Endophytic and (hemi)biotrophic fungi induce UGT76B1 degradation and FMO1 expression, resulting in varying levels of NHP being released to the shoot, where this root signal differently modulates defence and growth. Root microorganisms can trigger the release of immune-stimulating N-hydroxypipecolic acid from Arabidopsis roots by manipulating a standby circuit of its continuous synthesis and immobilization. N-hydroxypipecolic acid thereby influences shoot growth and pathogen defence.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 8","pages":"1658-1669"},"PeriodicalIF":13.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41477-025-02053-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, systematic methods for identifying key genes for long-distance regulation are currently unavailable. Here we present a new approach, trans-organ analysis of gene co-expression networks, which offers a unique way of identifying candidates for such genes. This approach revealed that TGA7 functions as a shoot-to-root mobile bZIP transcription factor in Arabidopsis to activate photosynthetic genes directly in shoots and nitrate-uptake-related genes, both directly and via a transcriptional cascade, in roots. Analysis of grafted chimeras showed that nitrogen-deficiency-induced enhanced TGA7 expression in shoot vascular tissue promotes TGA7 protein accumulation in roots, boosting root growth and nitrate uptake. Furthermore, the loss of TGA7-mediated long-distance regulation perturbed the balance between shoot and root development under nitrogen deficiency. These findings underscore the utility of our approach for uncovering long-distance regulation in plants. Trans-organ analysis of gene co-expression networks in different tissues provides a unique method for uncovering long-distance regulation.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 8","pages":"1544-1557"},"PeriodicalIF":13.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640382","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 plants, dozens of TF families interact with distinct sets of binding sites (TFBSs) that reflect each TF’s role in organismal function and species-specific adaptations. However, defining these roles and understanding broader patterns of regulatory evolution remain challenging, as predicted TFBSs may lack a clear impact on transcription, and experimentally derived TF binding maps to date are modest in scale or restricted to model organisms. Here we present a scalable TFBS assay that we leveraged to create an atlas of nearly 3,000 genome-wide binding site maps for 360 TFs in ten species spanning 150 million years of flowering plant evolution. We found that TF orthologues from distant species retain nearly identical binding preferences, while on the same timescales the gain and loss of TFBSs are widespread. Within lineages, however, conserved TFBSs are over-represented and found in regions harbouring signatures of functional regulatory elements. Moreover, genes with conserved TFBSs showed striking enrichment for cell-type-specific expression in 14 single-nucleus RNA atlases, providing a robust marker of each TF’s activity and developmental role. Finally, we compare distant lineages, illustrating how ancient regulatory modules were recruited and rewired to enable adaptations underlying the evolutionary success of grasses. A highly scalable approach is used to generate 3,000 genome-wide maps of transcription factor binding in ten flowering plants, along with multi-species single-nucleus RNA-seq atlases. Together, the results reveal both ancient regulation and key regulatory adaptations.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 8","pages":"1514-1527"},"PeriodicalIF":13.6,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629619","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}
