These processes have often been studied in isolation, even though proper flower development requires their coordination in space and time. This review synthesizes current insights into early floral organ initiation and identity determination, and potential molecular links bridging these two programs.

This review emphasizes on Ca<sup>2+</sup> decoding, i.e. how diverse intracellular proteins interpret Ca<sup>2+</sup> signals to drive cellular reactions. States of “Ca<sup>2+</sup> responsiveness” — defined by the distinct sensitivities of various decoders and additional sensitization mechanisms — contribute to the regulation of immunity, possibly including the mutual potentiation of pattern- and effector-triggered immunity pathways. Additionally, the “PRIMER-bystander” model of immune signalling is interpreted within this decoding framework. Here, infected cells are proposed to enter a primed (PRIMER) immune state through strong Ca<sup>2+</sup> signals derived from resistosome pores, while adjacent bystander cells respond to spreading signalling molecules from their neighbours. Through this spatial arrangement, coordination is achieved between cell-autonomous (autocrine) responses and non-autonomous (paracrine or endocrine) signalling, allowing robust immune propagation across plant tissues. By framing plant immunity through this Ca<sup>2+</sup> “sense and sensitivity” paradigm, insights are provided into immune system robustness, and potential targets may be identified for future development of disease-resistant, climate-resilient crops.</div></div>","PeriodicalId":11003,"journal":{"name":"Current opinion in plant biology","volume":"87 ","pages":"Article 102782"},"PeriodicalIF":7.5,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144916862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
