摘要:
延伸因子复合体(Elongator, ELP)是一类在真核细胞转录中起延伸RNA聚合酶II作用的蛋白质复合物, 这类复合体在植物生长发育以及生物和非生物胁迫响应等方面均发挥着重要作用。本研究利用生物信息学的方法对水稻(Oryza sativa) ELP基因家族(OsELPs)成员进行鉴定, 并进一步对其理化性质、亚细胞定位、染色体定位、启动子顺式作用元件及在非生物胁迫下的表达模式进行分析。结果表明: OsELPs基因家族含有6个成员、随机分布在水稻5条染色体上, 这6个基因编码含250~1344个氨基酸残基的蛋白质, 其分子量介于27.97~148.99 kD, 等电点介于5.01~8.63。系统进化分析将来源于水稻(Oryza sativa)、拟南芥(Arabidopsis thaliana)、酵母(Saccharomyces cerevisiae)和人类(Homo sapiens)的ELPs蛋白分为4个亚组(Group I~Group IV), 其中第I亚组包含OsELP1, 第II亚族包含OsELP2和OsELP5, 第III亚组包含OsELP4, 而第IV亚组包含OsELP3和OsELP6。OsELPs的启动子区域中存在多种顺式作用元件, 主要响应光、植物激素、干旱、低温、防御和逆境等信号。在PEG、低温、高盐以及脱水等4种非生物胁迫下, 6个OsELPs基因均有不同程度的差异表达, 其中OsELP6在4种非生物胁迫下均显著诱导上调表达, 该基因可能介导水稻对多种非生物逆境的综合抗性。
