摘　要：

植物激素脱落酸(ABA)参与诱导种子休眠、叶片脱落、气孔关闭以及抑制细胞生长等生理过程, 在调控植物根系发育中也具有重要作用。本文综述了近年来ABA在植物主根、侧根、不定根和根毛中的调节作用, 以及与其他信号的相互作用关系的研究进展。

Abstract:

Plant hormone abscisic acid (ABA) can induce seed dormancy, leaf abscission and stomatal closure, inhibit cell growth and regulate other physiological processes. It also plays an important role in the regulation of plant root development. Here we summarize some recent progresses on the roles of ABA in regulating the development of the primary root, lateral root, adventitious root and root hair, and the interaction between ABA and other signals in such regulations.

Key words: abscisic acid; roots; hormone interaction
