| 摘 要： | 生长素在植物的整个生长发育过程中都具有重要的作用,其早期响应基因可归为3类:Aux/IAAs、GH3s、SAURs.通过功能基因组学的研究,特别是对相关突变体的分子遗传学与分子生物学的研究,使我们对这些基因家族的作用机理的理解更为深入.以下综述了植物GH3基因的结构、功能及表达调控模式,重点介绍了由GH3介导的生长素信号途径与其他信号转导途径之间的互作和GH3基因与植物逆境胁迫适应的关系.

| Abstract: | Phytohormone auxins play important roles in plant growth and development. The primary auxin-response genes can be classified into three major groups: Aux/IAAs, SAURs and GH3s. Significant progress has been made in understanding these gene families by approaches of the functional genomics, molecular genetics and molecular biology. In this review, we focused on the structures, functions and models of the expressional regulation of plant GH3 genes. The interactions in the signal transduction pathways between auxins and other signals mediated by the GH3 genes, the relationship between the GH3 genes and the stress adaptation responses of plants are emphasized. |
