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 <i>Arabidopsis</i>. 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.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"29 1","pages":""},"PeriodicalIF":18.0,"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 <i>Capsicum</i> 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 <i>Capsicum</i>, 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.

AtPHO1 and AtPHO1;H1 are prototypical members of the unique SPX–EXS family, whose structural and molecular mechanisms remain elusive. In this study, we determined the cryogenic electron microscopy structure of AtPHO1;H1 binding with inorganic phosphate (Pi) and inositol hexakisphosphate in a closed conformation. Further molecular dynamic simulation and AlphaFold prediction support an open conformation. AtPHO1;H1 forms a domain-swapped homodimer that involves both the transmembrane ERD1/XPR1/SYG1 (EXS) domain and the cytoplasmic SYG1/Pho81/XPR1 (SPX) domain. The EXS domain presented by the SPX–EXS family represents a novel protein fold, and an independent substrate transport pathway and substrate-binding site are present in each EXS domain. Two gating residues, Trp719 and Tyr610, are identified above the substrate-binding site to control opening and closing of the pathway. The SPX domain features positively charged patches and/or residues at the dimer interface to accommodate inositol hexakisphosphate molecules, whose binding mediates dimerization and enhances AtPHO1;H1 activity. In addition, a C-terminal tail is required for AtPHO1;H1 activity. On the basis of structural and functional analysis, a working model for Pi efflux mediated by AtPHO1;H1 and its homologues was postulated, suggesting a channel-like mechanism. This study not only reveals the molecular and regulatory mechanism underlying Pi transport mediated by the unique SPX–EXS family, but also provides potential for crop engineering to enhance phosphorus-use efficiency in sustainable agriculture.</p>","PeriodicalId":18904,"journal":{"name":"Nature Plants","volume":"58 1","pages":""},"PeriodicalIF":18.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990651","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}
