Alternative splicing, a post-transcriptional mechanism that generates multiple transcripts from a single gene, enhances both the versatility and effectiveness of the plant immune system. Pathogen infection induces alternative splicing in numerous plant genes involved in the two primary layers of pathogen recognition: pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). However, the mechanisms underlying pathogen-responsive alternative splicing are just beginning to be understood. In this article, we review recent findings demonstrating that the interaction between pathogen elicitors and plant receptors modulates the phosphorylation status of splicing factors, altering their function, and that pathogen effectors target components of the host spliceosome, controlling the splicing of plant immunity-related genes.</p>","PeriodicalId":23264,"journal":{"name":"Trends in Plant Science","volume":" ","pages":""},"PeriodicalIF":17.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142865270","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}

TZP controls flowering and hypocotyl elongation by regulating gene expression and protein abundance in a blue, red, or far-red light-specific context.
