摘要:

种子发育是一个复杂的生物学过程,受各种遗传和外界因素的调节,显著影响农作物特别是禾谷类作物的种子活力和产量与质量。脱落酸(ABA)是调控种子发育和萌发最重要的植物激素之一,其活性水平、信号转导及其LAFL网络在种子发育包括胚胎发生和成熟过程的调控中起关键作用。该文主要综述了近年来ABA调控种子发育的研究取得的重要进展,包括ABA代谢和信号转导对种子发育的调控,ABA与种子成熟转录因子(AFL-B3、FUS3、ABI3、LEC2等)的作用,以及ABA在种子发育中的作用机制,并提出了需要进一步研究的科学问题, 为深入理解种子发育的分子机制提供参考,从而提高种子的活力、产量和质量。

Abstract:

Seed development is a complex biological process that is controlled by various genetic and external factors, and significantly affects the seed vigor, yield and quality of crops, especially cereal plant crops. Abscisic acid(ABA)is one of the most important phytohormones that regulate seed development and germination, and plays a key role in regulation of seed development through its activity level, signaling, and LAFL network, including embryogenesis and maturation process. In recent years, important progresses have been acquired in the research of seed development regulated by ABA. In the present paper, we have mainly reviewed the research achievements in this field, including the regulation of ABA metabolism and signaling on seed development, the action between ABA and transcription factors of seed maturation(AFL-B3, FUS3, ABI3, LEC2, etc.), and the action mechanism of ABA in seed development. In addition, we also propose some scientific questions that need to be further investigated in this field to provide some information for deeply understanding the molecular mechanism of seed development, so as to improve seed vigor and increasing yield and quality.
