| 摘 要： | 生长素是调控植物侧根发育的关键植物激素，生长素运输载体PIN蛋白介导其极性分布。ABI4抑制生长素极性运输蛋白基因PIN1的表达，影响生长素的极性运输，抑制侧根形成。本文概述ABI4转录因子调控侧根发育的研究进展。

| Abstract: | Auxin has been shown to be the key plant hormone in regulating lateral root(LR) development in plant.The auxin-efflux carrier proteins PIN effect the auxin polar distribution in roots.ABI4 inhibits LR formation due to the reduced PIN1 expression and that the resulting decrease in root auxin leads to a reduction in LR development.In this article,the current research advances on ABI4 mediated LR formation are introduced. |

| Keywords: | ABI4 PIN1 polar auxin transport lateral root formation |
