采用生物信息学方法,对葡萄(Vitis vinifera) BZR (brassinazole resistant)转录因子家族成员基因结构、进化特征及表达模式进行系统分析,为解析该基因家族功能提供参考.结果 表明,从葡萄基因组中共鉴定出6个BZR基因,命名为VvBZR1-1~VvBZR1-6.进化发育分析将葡萄BZR基因划分为3组,同在一个进化分类的成员其基因结构相似.顺式作用元件分析发现葡萄BZR基因上游启动子序列包含许多与激素和逆境响应相关的调控元件,说明葡萄BZR基因可能参与激素和逆境信号的调控过程.组织特异性表达分析显示,大多数BZR基因在种子、卷须、根中表达量较高.低温、高温、水分胁迫下葡萄B狱基因表达谱分析结果表明,BZR家族基因在非生物胁迫处理下受到不同程度诱导,其中VvBZR1-3响应3种胁迫处理,而VvBZR1-4、VvBZR1-6分别在水分胁迫、高温胁迫下高表达.这些结果表明BZR基因在葡萄响应非生物胁迫中起重要作用.
