摘要: 本文概述了侧根发生及其植物激素调控的研究进展。侧根的发生起源于特定的中柱 鞘细胞,其发生过程可简单地分为侧根发生的起始、侧根原基的形成、侧根分生组织的形成和活化等几个关键时期。参与侧根发生调控的植物激素主要是生长素,它影响到侧根发生过程的各个时期。茉莉酸对侧根的发生也有一定的调控作用。

Abstract: Lateral root occurs from some special cells in the pericycle of parent root. Lateral root initiation, lateral root primordium formation, and formation and activation of lateral meristem are some key stages for lateral root formation. Auxin action is involved in all the stages of lateral root formation, and jasmonic acid has some effects on the regulation of lateral root formation too.
