This review highlights recent advances in studies of mechanisms underlying the effects of five phytohormone groups: auxin, cytokinin, gibberellin, abscisic acid, and ethylene. The review summarizes data on receptors of all these phytohormones and the hormone signal transduction systems, which include second messengers, hormone-dependent trans-factors, and the genes controlled by these factors. The effects of phytohormones involve not only induction of novel protein synthesis via activation of their gene expression, but also degradation of repressor proteins through the ubiquitin system. The review contains examples of successful use of data on genes encoding enzymes of phytohormone synthesis and their receptors for development of transgenic plants with particular hormonal characteristics that provide practically valuable traits.
本综述重点介绍了五大类植物激素（生长素、细胞分裂素、赤霉素、脱落酸和乙烯）作用机制研究的最新进展。该综述总结了所有这些植物激素受体以及激素信号转导系统的数据，其中包括第二信使、激素依赖性转录因子以及受这些因子控制的基因。植物激素的作用不仅包括通过激活基因表达诱导新蛋白质合成，还包括通过泛素系统降解阻遏蛋白。该综述包含了一些成功利用植物激素合成酶及其受体的编码基因数据培育具有特定激素特性的转基因植物的实例，这些特性具有实际应用价值。
