Abstract
DELLA proteins act as negative regulators in gibberellin (GA) signal transduction. GA-induced DELLA degradation is a central regulatory system in GA signaling pathway. Intensive studies have revealed the degradation mechanism of DELLA and the functions of DELLA as a transcriptional regulator. Meanwhile, recent studies suggest the existence of a DELLA-independent GA signaling pathway. In this review, we summarized the DELLA-independent GA signaling pathway together with the well-analyzed DELLA-dependent pathway.
摘要
DELLA蛋白在赤霉素（GA）信号转导中作为负调控因子发挥作用。GA诱导的DELLA降解是GA信号通路中的一个核心调控系统。深入研究揭示了DELLA的降解机制以及DELLA作为转录调节因子的功能。与此同时，最近的研究表明存在一条不依赖DELLA的GA信号通路。在这篇综述中，我们总结了不依赖DELLA的GA信号通路以及已被充分分析的依赖DELLA的通路。
