摘要
同源域—亮氨酸拉链蛋白(HD-Zip)是高等植物中特有的一类转录因子,包含高度保守的同源异型域(HD),HD羧基末端与亮氨酸拉链域(LZ)紧密相连。同源域—亮氨酸拉链蛋白ATHB6是蛋白磷酸酶ABI1的靶蛋白,与发育中器官的细胞分裂和分化有关,是特异的ABA反应的负调控因子。ATHB6的表达受缺水、高渗、外源ABA及光的特异性调控。综述了ATHB6的相关结构、功能的新进展。
The homeodomain leucine zipper proteins （HD-Zip）are special transcription factors in higher plants. HD-Zip is characterized by a highly conserved homeodomain and a leucine-zipper domain linked closely to the C-terminal of the homeodomain. HD-Zip ATHB6 is a target of the protein phosphatase ABI1. Data suggested that ATHB6 was related to cell division and/or differentiation in developing organs. ATHB6 represented a hog,tire regulator of the ABA signal pathway. The expression of ATHB6 was regu- lated in seedlings subjected to water deficit, osmotic stress, exogenous treatment with abscisic acid （ABA） or light quality. This article focuses on a brief introduction on the latest development of the structure and functions of HD-Zip ATHB6.
