However, the underlying molecular mechanisms remain poorly understood. In this study, we identify sugar transport protein 2 (STP2) as a critical regulator of tomato fruit locule development under cold conditions. Low temperatures impair long-distance sucrose transport from leaves to shoot apices, resulting in reduced accumulation of glucose and arabinose. In response, STP2 expression is strongly upregulated in shoot apices, promoting glucose and arabinose transport. We found that the CLAVAT3-WUSCHEL (CLV3-WUS) regulatory module, which governs locule formation, relies on STP2-mediated sugar transport for CLV3 arabinosylation. Overexpression of STP2 promotes glucose and arabinose accumulation in shoot apices, enhances CLV3 arabinosylation and the WUS suppression, mitigating the multi-locular malformations induced by low temperatures. Conversely, disruption of STP2 function exacerbates locule number increases under low temperatures, which could not be rescued by exogenous sugar supplementation. Our findings reveal a key mechanism by which STP2-mediated sugar transport supports CLV3 arabinosylation to maintain fruit locule development under low temperatures, offering potential strategies to alleviate fruit malformations in winter crop cultivation.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"1014-1028"},"PeriodicalIF":17.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144019154","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 this study, we investigated the conservation and divergence of transcriptional responses to hypoxia across major land plant clades. We found that the induction of gene functions associated with glycolysis and fermentation is part of a conserved response across all land plant divisions.Evolutinary analyses suggest that ERFVIIs emerged in the last common ancestor of vascular plants with true roots, coinciding with the evolution of oxygen-dependent destabilization mechanisms that regulate hypoxia-adaptive genes. Proteins from other ERF groups have been independently recruited multiple times in different clades as substrates of the PCO N-degron pathway. Taken together, our results demonstrate that the response of land plants to hypoxia has been refined in derived clades through the evolution of ERFVIIs as transcriptional transducers, which occurred concurrently with the emergence of vascular systems and roots as foraging structures in hypoxic soils.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"1072-1087"},"PeriodicalIF":17.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144174189","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}

However, genomic variability remains largely understudied. Here, we present the full-spectrum integrated panvariome and pangenome of 1,020 peach accessions, including 10.5 million single-nucleotide polymorphisms, insertions, deletions, duplications, inversions, translocations, copy-number variations, transposon-insertion polymorphisms, and presence-absence variations, uncovering 70.6% novel variants and 3,289 novel genes. Analysis of the panvariome recapitulated the global evolutionary history of the peach and identified several novel trait-causally rare variants. We found that landraces and improved accessions encode more genes than the wild accessions, implying gene gains during peach domestication and improvement. Analysis of global introgression patterns revealed their value in phenotype prediction and gene mining, and suggested that the most likely wild progenitor of the domesticated peach is Prunus mira and that almond was involved in the origin of Prunus davidiana. Furthermore, we developed a novel panvariome-based one-step solution for association study, GWASPV, which was used to identify several trait-conferring genes and over 2,000 novel associations.. Collectively, our study reveals new insights into peach evolution and genomic variations, providing a novel method for plant gene mining and important targets for peach breeding.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"995-1013"},"PeriodicalIF":17.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002084","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}

NADH is mainly involved in catabolic reactions, whereas NADPH is mainly involved in anabolic and antioxidative reactions. The presence of endosymbiont-derived organelles in eukaryotes has made the functional division of NADH and NADPH systems more complex. Chloroplasts in photoautotrophic eukaryotes provide additional sources of reductants, complicating the maintenance of the redox balance of NAD(P)+/NAD(P)H compared with heterotrophic eukaryotes. In this review, we discuss the two redox systems in plants and systematically compare them with those in mammals, including the similarities and differences in the biosynthesis and subcellular transport of NAD+, the biosynthesis of NADP+, and metabolic reactions for the reduction and oxidation of NAD(P)H. We also review the regulation of pyridine nucleotide pools and their ratios in different plant subcellular compartments and the effects of light on these ratios. We discuss the advantages of having both NADH and NADPH systems, highlight current gaps in our understanding of NAD(P)H metabolism, and propose research approaches that could fill in those gaps. The knowledge about NADH and NADPH systems could be used to guide bioengineering strategies to optimize redox-regulated processes and improve energy-use efficiency in crop plants.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"938-959"},"PeriodicalIF":17.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12178909/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079150","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}

However, the molecular mechanisms underlying symptom development in viral infections remain largely unexplored. Here, we show that tomato yellow leaf curl virus (TYLCV) interferes with host developmental programs through a host-mimicking domain present in the viral C4 protein. This domain mediates the interaction between C4 and a family of RCC1-like domain-containing (RLD) proteins, previously shown to be required for proper plant development and environmental responses. C4 outcompetes an endogenous interactor of RLDs, hijacking RLD proteins to the plasma membrane and disrupting their function in orchestrating endomembrane trafficking and polar auxin transport. Strikingly, macroscopic symptoms do not affect viral accumulation in the plant but serve as attractants for the insect vector, presumably promoting pathogen spread in an ecological context. Our work sheds light on the molecular underpinnings and biological relevance of symptom development triggered by TYLCV in tomato. Since most plant viruses are insect-transmitted, the principles described here might have broad applicability to crop-virus interactions.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"1029-1046"},"PeriodicalIF":17.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144151334","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}
