Flowering plants have evolved sophisticated and complicated reproductive structures to ensure optimal conditions for the next generation. Successful reproduction relies on careful timing and coordination of tissue development, which requires constant communication between these tissues. Work on flower and fruit development over the last decade places the phytohormone auxin in a key role as a master of patterning and tissue specification of reproductive organs. Although many questions still remain, it is now clear that auxin mediates its function in flowers and fruits through an integrated process of biosynthesis, transport, and signaling, as well as interaction with other hormonal pathways. In addition, the knowledge obtained so far about auxin function already allows researchers to develop tools for crop improvement and precision agriculture.
开花植物进化出了复杂精细的生殖结构，以确保下一代的最佳条件。成功的繁殖依赖于组织发育的精心定时和协调，这需要这些组织之间的持续沟通。过去十年中对花和果实发育的研究将植物激素生长素置于关键位置，作为生殖器官模式形成和组织特化的大师。尽管仍有许多问题尚未解决，但现在很清楚，生长素通过生物合成、运输和信号转导的综合过程以及与其他激素途径的相互作用来介导其在花和果实中的功能。此外，迄今为止获得的关于生长素功能的知识已经使研究人员能够开发用于作物改良和精准农业的工具。
