摘　要：摘　要：细胞分裂素作为重要的植物激素广泛参与植物生长发育。尽管细胞分裂素的作用已经广为人知，但是作为激素信号的效应器，其响应调节因子的作用未见综合报道。现就以拟南芥为例，介绍拟南芥响应调节因子在根生长发育、顶端分生组织发育及叶子形态发生中的作用。

Abstract: Abstract: Cytokinins are plant hormones that play essential roles in regulating plant growth and development. Although cytokinins have long been widely studied， only recently have we begun to understand the molecular mechanisms underlying cytokinin signal transduction. The Arabidopsis Response Regulators (ARRs) are critical members in the two-component system of cytokinin signal transduction. In this review， we focus on the functions of ARRs in the development of root， shoot apical meristem and leaf morphogenesis in Arabidopsis.
