种子适时休眠与萌发确保植物在不同环境条件下能够有效地生存和繁衍,该过程受到多种内源激素和外在环境因子的精确调控。近些年,脱落酸(ABA, abscisic acid)和赤霉素(GA, gibberellin)调控种子休眠与萌发的研究取得了重要进展,尤其是二者交互调控休眠与萌发等方面有所突破。本文详细阐述了ABA与GA的代谢过程以及信号转导通路在基因转录水平和蛋白翻译后水平调控种子休眠和萌发的分子机制,进一步探讨了二者介导种子休眠与萌发之间的拮抗作用及其交互关系,并系统总结了ABA和GA的代谢及信号转导通路如何响应外界光温环境变化进而精确调控种子休眠与萌发的研究进展,以期为更好地理解种子休眠与萌发的激素调控网络以及未来对ABA与GA调控种子休眠萌发机制的深入研究提供理论参考。
Timely seed dormancy and germination ensures that plants could successively survive and subsequently propagate under various environmental conditions, which is precisely regulated by endogenous phytohormones and exogenous environmental factors. In recent years, significant progress has been made in the regulation of seed dormancy and germination by abscisic acid (ABA) and gibberellin (GA), particularly with regard to the interaction between them. This article elaborates the molecular mechanisms underlying seed dormancy and germination regulated by the metabolism and signal transduction of ABA and GA at the transcriptional and post-translational levels. It further explores the antagonistic effects and interactions in mediating seed dormancy and germination between ABA and GA. Lastly, it comprehensively summarizes the research progress on the regulatory mechanisms by which the metabolism and signaling pathway of ABA and GA finely regulate seed dormancy and germination in response to external light and temperature signals. The aim of this review is to provide a better understanding of the hormone regulatory network of seed dormancy and germination and theoretical references for future in-depth studies on the mechanisms of seed dormancy and germination regulation by ABA and GA.
