摘　要：

生长素结合蛋白ABP1在植物胚胎发生与发育, 根、下胚轴和叶的生长发育, 以及向性生长中起重要调控作用。ABP1作为可能的生长素受体, 其功能主要通过与生长素结合并快速传递信号, 介导生长素早期响应基因转录和膜蛋白内吞, 调控细胞生长、分裂与分化等过程。本文主要介绍ABP1的研究历史、分子结构与亚细胞定位、遗传学研究、细胞生物学功能及其分子作用机理。

Abstract:

Auxin binding protein1 (ABP1) plays an essential role in embryogenesis, growth and development of roots, hypocotyls, leaves, and tropic growth. ABP1 as a putative auxin receptor, mediates auxin early response gene transcription and membrane protein endocytosis to regulate cell expansion, cell division and differentia-tion through binding auxin and triggering rapid signal transduction. This review focused on ABP1’s study histo-ry, molecular structure and subcellular localization, genetic study, cellular functions, and molecular action mechanisms.

Key words: auxin; auxin binding protein1; biological functions; signal transduction
