摘要

根系结构发育是影响作物产量的一个农艺性状,受多种植物激素的调节。脱落酸(ABA)是一种应激激素,对包括盐、干旱和冷胁迫在内的多种胁迫作出反应,并调节植物生长发育的各个方面。近年来,人们发现,在温和胁迫或良好浇水条件下合成的ABA可以通过积极调节根系结构发育来支持植物生长和抗逆性。在这篇综述中,我们总结了ABA在根中稳态的分子、细胞和组织基础,以及ABA信号如何作为抑制剂和激活剂影响根结构发育。我们讨论了这些研究的意义,以及利用ABA信号成分设计具有改善根系发育和抗逆性的作物的潜力。

Effects of stress-induced ABA on root architecture development: Positive and negative actions

Root architecture development, an agronomic trait that influences crop yield, is regulated by multiple plant hormones. Abscisic acid (ABA) is a stress hormone that responds to multiple stresses, including salt, drought, and cold stress, and modulates various aspects of plant growth and development. In recent years, it has been found that ABA synthesized under mild stress or well-watered conditions can support plant growth and stress resistance by positively regulating root architecture development. In this review, we summarize the molecular, cellular, and organismal basis of ABA homeostasis in the root and how ABA signaling affects root architecture development both as an inhibitor and as an activator. We discuss the implications of these studies and the potential for exploiting the components of ABA signaling in designing crop plants with improved root system development and stress resistance.
