Two chloroplast ClpC AAA+ chaperones and the plant-specific adaptor ClpF contain an Uvr motif with predicted coiled-coiled structures implicated in protein-protein interactions. Head-to-head contacts between Uvr motifs in middle (M)-domains regulate the oligomerization and activation of several bacterial Clp chaperones. Interestingly, in arabidopsis (Arabidopsis thaliana), this Uvr motif is found in six additional chloroplast proteins (Executer1, Executer2, and Uvr1-4). Here, we first summarize evidence that Uvr motifs regulate proteostasis in bacteria. Based on this evidence and recent results in arabidopsis, we postulate that arabidopsis Uvr motif proteins regulate chloroplast Clp proteolysis. We propose specific working hypotheses to test the function of the Uvr motif in chloroplast proteostasis.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":"269-282"},"PeriodicalIF":17.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142508732","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}

Crop quality often depends on pollinator movement patterns, which vary with cultivar selection and spatial arrangement, pollen donor identity, and landscape context. Transfer of the right pollen between cultivars may fail, as pollen is often not transported far, even by highly dispersive pollinators, reducing cross-pollination and crop quality. Both pollinator identity and complementary spatiotemporal activity of diverse pollinators can shape crop quality. Here, we argue that promoting crop quality needs better understanding of species-specific pollinator behaviour and cultivar distribution patterns, rather than only focusing on enhancing pollinator densities.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":"283-290"},"PeriodicalIF":17.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142563827","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, using core principles of community assembly and invasion biology, we discuss how the invasibility of non-native plants during and after extreme droughts differs due to: (i) differences in the ecological response of the native community, (ii) barriers at different invasion stages, and (iii) the traits of non-native plants.
