It has long been hypothesized that vesicles are directionally transported along phragmoplast microtubules by motor proteins. However, the mechanisms governing the accumulation and immobilization of vesicles at the phragmoplast midzone remain elusive, and the motor protein responsible has yet to be identified. Here we show that the plant-specific class II kinesin-12 (kinesin12-II) functions as a motor protein that drives vesicle transport towards the phragmoplast midzone in the moss Physcomitrium patens. In the kinesin12-II mutant, the directional movement of cell plate materials towards the midzone and their retention were abolished, resulting in delayed cell plate formation and phragmoplast disassembly. A macroscopic phenotype arising from kinesin12-II disruption was the impediment to gametophore development. We showed that this defect was attributable to the production of aneuploid and polyploid cells in the early gametophore, where chromosome missegregation and cytokinesis failure occurred. These findings suggest that plant kinesin-12 has evolved to acquire a unique and critical function that facilitates cell plate formation in the presence of phragmoplasts. Class II kinesin-12 is responsible for transporting vesicles containing cell plate materials along phragmoplast microtubules towards the midzone, facilitating efficient cell plate formation during cytokinesis and enabling sequential cell division during multicellular organ development.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 2","pages":"340-358"},"PeriodicalIF":15.8,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083417","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}

The functions and mechanisms of iron in nitrogen-fixing nodules are well established. However, the role of iron and the mechanisms by which legumes sense iron and incorporate this cue into nodulation signalling pathways remain unclear. Here we show that iron is a key driver of nodulation because symbiotic nodules cannot form without iron, even under conditions of sufficient light and low nitrogen. We further identify an iron optimum for soybean nodulation and the iron sensor BRUTUS A (BTSa) which acts as a hub for integrating iron and nodulation cues. BTSa is induced by rhizobia, binds to and is stabilized by iron. In turn, BTSa stabilizes and enhances the transcriptional activation activity of pro-nodulation transcription factor NSP1a by monoubiquitination from its RING domain and consequently activates nodulation signalling. Monoubiquitination of NSP1 by BTS is conserved in legumes to trigger nodulation under iron sufficiency. Thus, iron status is an essential cue to trigger nodulation and BTSa integrates cues from rhizobial infection and iron status to orchestrate host responses towards establishing symbiotic nitrogen fixation. The authors report that iron binds to and stabilizes the iron sensor BRUTUS A (BTSa), which monoubiquitinates the pro-nodulation transcription factor NSP1a to increase its stability and transcriptional activity, thereby regulating nodulation in legumes.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 3","pages":"595-611"},"PeriodicalIF":15.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077618","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 report that Plant Nuclear Envelope Transmembrane 1 (PNET1), a transmembrane nucleoporin, is an adaptable NPC component that is mainly expressed in actively dividing cells. PNET1’s selective incorporation into the NPC is required for rapid cell growth in highly proliferative meristem and callus tissues in Arabidopsis. We demonstrate that the cell cycle-dependent phosphorylation of PNET1 coordinates mitotic disassembly and post-mitotic reassembly of NPCs during the cell cycle. PNET1 hyperphosphorylation disrupts its interaction with the NPC scaffold, facilitating NPC dismantling and nuclear membrane breakdown to trigger mitosis. In contrast, nascent, unphosphorylated PNET1 is incorporated into the nuclear pore membrane in the daughter cells, where it restores interactions with scaffolding nucleoporins for NPC reassembly. The expression of the human PNET1 homologue is required for and markedly upregulated during cancer cell growth, suggesting that PNET1 plays a conserved role in facilitating rapid cell division during open mitosis in highly proliferative tissues. The nuclear pore complex is a cornerstone of eukaryotic cell function. This study identifies a cell-type-specific nucleoporin that regulates mitotic disassembly and reassembly of the nuclear pore complex, serving as a critical mechanism to promote rapid cell division.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 2","pages":"295-308"},"PeriodicalIF":15.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071725","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 present 11 high-quality Capsicum genome assemblies, including two gap-free genomes, covering four wild and all five domesticated pepper species. We reconstructed the ancestral karyotype and inferred the evolutionary trajectory of peppers. The expanded and variable genome sizes were attributed to differential transposable element accumulations, which shaped 3D chromatin architecture and introduced mutations associated with traits such as fruit orientation and colour. Using a chromatin accessibility atlas of Capsicum, we highlight the influence of transposable elements on regulatory element evolution. Furthermore, by constructing a haploblock map of 124 pepper core germplasms, we uncover frequent introgressions that facilitate the formation of sweet blocky pepper and the acquisition of important traits such as resistance to pepper mild mottle virus. These findings on the genomic and functional evolution of Capsicum will benefit pepper breeding. This study presents 11 telomere-to-telomere genomes of wild and domesticated pepper, highlights how transposable elements have shaped the evolution of genome structure and regulatory elements and identifies structural variations and introgressions associated with key traits in cultivated pepper.","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"11 2","pages":"359-375"},"PeriodicalIF":15.8,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049914","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}
