The plant phytohormones brassinosteroids (BRs) and the MAPK signaling cascade are known to play crucial roles in regulating leaf angle, but the underlying molecular mechanisms are not fully understood. Here, we report a rice WRKY family transcription factor gene, OsWRKY72, which positively regulates leaf angle by affecting lamina joint development and BR signaling. Phenotypic analysis showed that oswrky72 mutants have smaller leaf angles and exhibit insensitivity to exogenous BRs, whereas OsWRKY72 overexpression lines show enlarged leaf angles and are hypersensitive to exogenous BRs. Histological sections revealed that the change in leaf inclination is due to asymmetric cell proliferation and growth at the lamina joint. Further investigation showed that OsWRKY72 binds directly to the promoter region of BR receptor kinase (OsBRI1), a key gene in the BR signaling pathway, and activates its expression to positively regulate rice BR signaling. In addition, we discovered that OsWRKY72 interacts with and is phosphorylated by OsMAPK6, and this phosphorylation event can enhance OsWRKY72 activity in promoting OsBRI1 expression. Genetic evidence confirmed that OsMAPK6, OsWRKY72, and OsBRI1 function in a common pathway to regulate leaf angle. Collectively, our findings clarify the critical role of the OsWRKY72 transcription factor in regulating rice leaf angle. These results provide valuable insights into the molecular regulatory networks that govern plant architecture in rice.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101236"},"PeriodicalIF":9.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11956091/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900339","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}

Here, we identified 198 985 DSCNVs by investigating 491 genomes of common wheat and found that they account for 20% of the entire genome. Interestingly, approximately 38% of genes are linked to DSCNVs. The number of DSCNVs within each accession ranges from 47 366 to 96 342, and their total sizes vary from 421.3 to 1267.9 Mb. We found that 957 and 1304 DSCNVs have been favored by breeders in China and the United States, respectively. By conducting DSCNV-based genome-wide association studies for the principal components of plant developmental and yield-component traits, we identified 34 loci as directly or indirectly involved in controlling the formation of multiple traits. Notably, a newly discovered DSCNV covering TaFT-D1 is significantly associated with flowering time and other agronomic traits. Overall, our findings highlight the potential of DSCNVs to drive fundamental discoveries in plant science.

An excessive focus on increasing yield often leads to a decline in quality. How to achieve the delicate balance between high yield and desirable fruit quality is still a big challenge. In this study, we discovered that disrupting the function of tomato tonoplast sugar transporter 3a (TST3a) can significantly enhance both fruit weight and flavor. In tomato, there are three TSTs, namely SlTST1, SlTST3a and SlTST3b, which possess same sugar transport specificity for fructose and glucose and redundantly control cell expansion during fruit development. The different levels of sugar accumulation in the sltst mutants significantly associated with the fruit size and flavor. The reason for the enlarged fruits of sltst3a mutants, which are a consequence of sugar accumulation, is the increased abundance of SlTST1 at the tonoplast and coupled with the highest sugar transport capacity of SlTST1. Further studies established that SlTST3a prevented the localization of SlTST1 to the tonoplast by inhibiting its interaction with VH1-interacting kinase (SlVIK). Mutation of SlTST3a in the cultivated tomatoes can simultaneously enhance tomato fruit size and sugar content. Our findings present potential avenues for simultaneously improving both fruit quality and yield and provide valuable insights into the mechanisms underlying the storage sugar for fruit development.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101314"},"PeriodicalIF":9.4,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587996","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 reconstruction of a nucleotide-binding leucine-rich repeat receptor (NLR) supramolecular structure, called the resistosome, is intimately involved in the hypersensitive response (HR), a type of cell death involved in effector-triggered immunity (ETI). Iron is a crucial redox catalyst in various cellular reactions. Ferroptosis is a regulated, non-apoptotic form of iron- and ROS-dependent cell death in plants. Pathogen infections trigger iron accumulation and ROS bursts in plant cells, leading to lipid peroxidation via the Fenton reaction and subsequent ferroptosis in plant cells similar to that in mammalian cells. The small-molecule inducer erastin triggers iron-dependent lipid ROS accumulation and glutathione depletion, leading to HR cell death in plant immunity. Calcium (Ca2+) is another major mediator of plant immunity. Cytoplasmic Ca2+ influx through calcium-permeable channels, the resistosomes, mediates iron- and ROS-dependent ferroptotic cell death under reduced glutathione reductase (GR) expression levels in the ETI response in plants. Acibenzolar-S-methyl (ASM), a plant defense activator, enhances Ca2+ influx, ROS and iron accumulation and lipid peroxidation to trigger ferroptotic cell death in plants. These breakthroughs suggest a potential role of Ca2+ signaling in ferroptosis and its coordination with iron and ROS signaling in plant immunity. In this review, we highlight the essential roles of calcium, iron, and ROS signaling in ferroptosis during plant immunity and discuss advances in the understanding of how Ca2+-mediated ferroptotic cell death orchestrates effective plant immune responses against invading pathogens.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101299"},"PeriodicalIF":9.4,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587989","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}

Perception of HIFs induces the rapid transformation of S. hermonthica radicles into prehaustoria, structures that enable host invasion and mature into haustoria. HIFs consist of various aromatic compounds, including quinones, lignin monomers, and flavonoids. However, the downstream molecular pathways that orchestrate these developmental events are largely unknown. Here, we report that S. hermonthica root-tip cells rapidly deposit lignin, a major cell wall component, in response to HIFs. In addition to enhancing lignin levels, HIFs strongly induce genes involved in lignin monomer biosynthesis and polymerization, including several respiratory burst oxidase homologs (RBOHs) and class III peroxidases. Disruption of lignin monomer biosynthesis compromises prehaustorium formation, whereas HIF-induced class III peroxidases facilitate the process by promoting lignification. Our study demonstrates that cell wall lignification is a converged cellular process downstream of various HIFs that guides root meristematic cells in prehaustorium development.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101294"},"PeriodicalIF":9.4,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143544407","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}

Consequently, the alterations in gene expression levels within these cells in response to the pathogens exhibit significant variability. These variations are pivotal in determining pathogenicity or susceptibility, yet they remain largely unexplored and poorly understood. Sugarcane mosaic virus (SCMV) is a representative member of the monocot-infecting potyviruses with a polyadenylated RNA genome, which could be captured by single-cell RNA sequencing (scRNA-seq). Here, we performed scRNA-seq with SCMV-infected maize leaves during the early systemic infection (prior to symptom manifestation) to investigate the co-variation patterns between viral accumulation levels and alterations in intracellular gene expression levels. We identified five cell types and found that mesophyll-4 (MS4) cells had the highest viral accumulation levels in most cells. The early systemic infection of SCMV resulted in up-regulation of most differentially expressed genes (DEGs), which were mainly enriched in biological processes related to translation, peptide biosynthesis and metabolism. Co-variation analysis of the altered maize gene expression levels and viral accumulation levels in MS1, 2 and 4 revealed several patterns, and the co-expression relationships between them were mainly positive. Furthermore, functional studies identified several potential anti- or pro-viral factors that may play crucial roles during the early stage of SCMV systemic infection. These results not only provide new insights into plant gene regulation during viral infection, but also offer feasible references for future investigations of host-virus interaction across molecular, cellular, and physiological scales.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101297"},"PeriodicalIF":9.4,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568805","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}
