摘要:
WRKY转录因子参与调节植物生长发育、生物与非生物胁迫应答等多种过程,AtWRKY28是拟南芥中与抗病和耐逆相关的重要转录因子。为探讨大豆中一个AtWRKY28同源基因GmWRKY28-like(Glyma.14G028900)的生物学功能,本文对该基因进行了克隆、生物信息学分析、亚细胞定位、组织表达等试验,并对其在ABA、PEG、NaCl胁迫下的表达水平进行了分析。结果显示,GmWRKY28-like基因的编码区(CDS)为1008bp,编码335个氨基酸。GmWRKY28-like蛋白具有保守的WRKY结构域,含有22个丝氨酸(Serine)、1个苏氨酸(Threonine)、2个酪氨酸(Tyrosine),不含跨膜结构与信号肽;进化树分析表明大豆GmWRKY28-like与菜豆(Phaseolus vulgaris)WRKY28的相似性最高;亚细胞定位显示GmWRKY28-like定位在细胞核中。该基因在根、种子中表达量很低,在真叶、花、及茎尖分生组织表达量较高。GmWRKY28-like启动子中含有多种与生物和非生物逆境胁迫应答相关的元件,如MBS、W-box、ABRE、Box-W1等,且表达受到ABA、PEG、NaCl的诱导。此外,过表达GmWRKY28-like显著增强了拟南芥的耐盐性。
