Even lost stem cells can be regenerated from non-stem cells after competence acquisition, highlighting the enormous plasticity of plant cells. However, the molecular mechanisms underlying this process are still poorly understood. In the root, the highly conserved microRNA miR396 and its targets, the GROWTH-REGULATING FACTORs (GRFs), control the transition from stem cells to proliferative cells. miR396 promotes stem cell activity by repressing and excluding the GRFs from the stem cell area. In turn, the GRFs promote cell division in the proliferation zone3. Here we show that the miR396–GRF regulatory module guides stem cell reconstitution after root tip excision, playing a dual role: while miR396 promotes competence, the GRFs control regeneration speed. Moreover, plants with ectopic miR396 expression have defined stem cell niches before the excision but do not reconstitute them afterwards, remaining in an open state despite continuing to grow. We propose that this phenomenon is caused by dispersed stem cell activity, which supports growth after root tip excision without reconstituting the organized and spatially restricted stem cell niche typical of Arabidopsis roots. The miR396–GRF module controls a trade-off between competence and speed during root tip regeneration in Arabidopsis. Roots ectopically expressing miR396 grow without stem cell niche reconstitution, probably due to dispersed stem cell activity.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"531-542"},"PeriodicalIF":15.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486380","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}

How niche cells maintain their own somatic developmental programme, yet support the development of adjoining germline cells, remains largely unknown. Here we report that MADS31, a conserved MADS-box transcription factor from the B-sister subclass, is a potent regulator of niche cell identity. In barley, MADS31 is preferentially expressed in nucellar cells directly adjoining the germline, and loss-of-function mads31 mutants exhibit deformed and disorganized nucellar cells, leading to impaired germline development and partial female sterility. Remarkably similar phenotypes are observed in mads31 mutants in wheat, suggesting functional conservation within the Triticeae tribe. Molecular assays indicate that MADS31 encodes a potent transcriptional repressor, targeting genes in the ovule that are normally active in the seed. One prominent target of MADS31 is NRPD4b, a seed-expressed component of RNA polymerase IV/V that is involved in epigenetic regulation. NRPD4b is directly repressed by MADS31 in vivo and is derepressed in mads31 ovules, while overexpression of NRPD4b recapitulates the mads31 ovule phenotype. Thus, repression of NRPD4b by MADS31 is required to maintain ovule niche functionality. Our findings reveal a new mechanism by which somatic ovule tissues maintain their identity and support germline development before transitioning to the post-fertilization programme. A somatic niche embraces the female germline in cereal ovules. MADS31 precisely maintains developmental progression of this niche to support the germline by repressing the post-fertilization programme.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"543-560"},"PeriodicalIF":15.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41477-025-01915-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485899","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}

Stomata, valves formed by guard cells (GCs), are present in most land plants and regulate CO2 exchange. The transcription factor (TF) FAMA globally regulates GC differentiation. In the Brassicales, FAMA also promotes the development of idioblast myrosin cells (MCs), another type of specialized cell along the vasculature essential for Brassicales-specific chemical defences. Here we show that in Arabidopsis thaliana, FAMA directly induces the TF gene WASABI MAKER (WSB), which triggers MC differentiation. WSB and STOMATAL CARPENTER 1 (SCAP1, a stomatal lineage-specific direct FAMA target), synergistically promote GC differentiation. wsb mutants lacked MCs and the wsb scap1 double mutant lacked normal GCs. Evolutionary analyses revealed that WSB is conserved across stomatous angiosperms. We propose that the conserved and reduced transcriptional FAMA–WSB module was co-opted before evolving to induce MC differentiation. The authors identified a transcriptional module, FAMA–WASABI MAKER (WSB), for the development of stomata and idioblast myrosin cells. They propose that the conserved and reduced FAMA–WSB module was co-opted before evolving to induce idioblast development.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"483-504"},"PeriodicalIF":15.8,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41477-025-01921-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477696","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}
