However, the emanating root triggers in these scenarios remain elusive. Here we identify an <i>N</i>-hydroxypipecolic-acid-(NHP-)directed, salicylic-acid-related mechanism of root-triggered systemic resistance in <i>Arabidopsis</i>, 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.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"98 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This ring is linked to the inner envelope membrane through ARC6 and further connected to the outer envelope membranes through PLASTID DIVISION proteins and to a cytosolic plastid division ring containing dynamin-like ARC5. The correct positioning of the Z ring depends on a chloroplast version of the Min system in which ARC3 has a key role as a negative regulator of Z ring formation. ARC3 displays a diffuse localization at non-division sites where it probably prevents Z ring formation. However, ARC3 also localizes to the Z ring itself, but the function of this subpopulation was unclear.</p><p>The researchers show that ARC3 physically interacts with ARC6, and that this interaction depends on its membrane occupation and recognition nexus (MORN) domain with which it was known to bind to the paralogue of ARC6 (PARC6). Indeed, localization of ARC3 in <i>arc6 parc6</i> and <i>arc6</i> mutant background suggests that there is some functional overlap between ARC6 and PARC6 in recruiting ARC3 to the Z ring. Expression of ARC3 with a deleted MORN domain abolishes filament assembly of FtsZ1 in a heterologous yeast system, providing evidence for the autoinhibitory function of this domain. Co-expression of ARC6 with ARC3 inhibited FtsZ1 filament formation, presumably due to interaction with the MORN domain, which may release the autoinhibitory function similar to PARC6. However, in contrast to PARC6, ARC6 has a J-like domain that prevents interaction with ARC3 in planta. Indeed, deletion of the J-like domain of ARC6 led to reduced FtsZ1 assembly and chloroplast division defects, similar to plants overexpressing ARC3. This is not the case in the <i>arc3</i> mutant background, suggesting that inhibition of FtsZ1 assembly depends on ARC3. Intriguingly, co-expression of ARC3 and ARC6 in the heterologous system <i>Pichia pastoris</i> led to enhanced Z ring constriction dynamics, suggesting that ARC3 function is not only negatively controlled by ARC6 within the Z ring but is also beneficial for constriction dynamics.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"44 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640366","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.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"3 1","pages":""},"PeriodicalIF":18.0,"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}
