细胞分裂素是一类调节植物生长发育各个方面的植物激素。在过去的十年中，遗传学和基因组学方法已经成功地鉴定了许多参与细胞分裂素从头合成、激活、失活和信号传导的基因。这些基因的特征不仅有助于确定细胞分裂素生物合成和信号传导的基本方案，而且还表明细胞分裂素在许多发育过程中起着至关重要的作用。此外，最近对水稻的研究突出了细胞分裂素作为作物改良的有希望的靶点。本章概述了目前对细胞分裂素生物合成和信号通路的理解，并总结了细胞分裂素参与植物发育的分子基础的最新发现。
Cytokinins are a class of plant hormones that regulate diverse aspects of plant growth and development. During the past decade, genetic and genomic approaches have succeeded in identifying many genes involved in the de novo synthesis, activation, inactivation, and signaling of cytokinin. Characterization of these genes has not only helped to define basic schemes of cytokinin biosynthesis and signaling, but has also demonstrated that cytokinins play a crucial role in numerous developmental processes. Furthermore, recent studies in rice have highlighted cytokinins as promising targets for crop improvement. This chapter gives an overview of our current understanding of the cytokinin biosynthesis and signaling pathways, and summarizes recent findings on the molecular basis for cytokinin involvement in plant development.
