植物进化出了保守和多样化的茉莉酸合成和信号传导基因。茉莉酸稳态和信号在植物生殖过程中发挥着多种作用。茉莉酸盐通过激活e类基因促进水稻小穗发育。茉莉酸盐通过多种调控网络控制雄蕊发育。茉莉酸盐的时空生物合成和转运在花的发育中起着关键作用。植物花序和花的发育受环境和遗传信号的共同作用。研究表明，植物激素茉莉酸（JA）在植物生殖过程中起着重要的作用，如雄性生殖、性别决定和种子成熟。本文就JA的合成、信号转导、与其他激素的相互作用以及JA在控制花序、花和雄性器官发育中的调控网络等方面的研究进展进行综述。强调了JAs在分生组织转变、花器官身份和数量规范中的保守性和多样性作用，以及JAs在雄蕊发育中的多重调控网络。此外，本文还对植物生殖发育过程中JAs稳态和转运机制的研究进行了展望。
HighlightsPlants evolved conserved and diversified genes for jasmonate biosynthesis and signaling.Jasmonate homeostasis and signaling play diverse roles in plant reproduction.Jasmonates promote rice spikelet development by activating E-class genes.Jasmonates control stamen development through multiple regulatory networks.Temporal and spatial biosynthesis and transport of jasmonates play pivotal roles in flower development.Development of inflorescences and flowers in plants is controlled by the combined action of environmental and genetic signals. Investigations reveal that the phytohormone jasmonate (JA) plays a critical function in plant reproduction such as male fertility, sex determination and seed maturation. Here, we review recent progress on JA synthesis, signalling, the interplay between JAs and other hormones, and regulatory network of JA in controlling the development of inflorescence, flower and the male organ. The conserved and diversified roles of JAs in meristem transition and specification of flower organ identity and number, and multiple regulatory networks of JAs in stamen development are highlighted. Further, this review provides perspectives on future research endeavors to elucidate mechanisms underlying JAs homeostasis and transport during plant reproductive development.
