髓细胞组织增生蛋白2(myelocytomatosis protein 2,MYC2)作为MYC型bHLH转录因子家族成员,是茉莉酸响应途径的关键转录因子,在调控植物抵抗逆境胁迫中具有重要作用。本研究基于NCBI数据库中野草莓(Fragaria vesca)的基因序列,从草莓(Fragaria×ananassa)品种‘红颜’(‘Benihoppe’)中克隆鉴定了1个FaMYC2-like基因,其开放阅读框长度为1473 bp,编码490个氨基酸残基。保守结构域分析表明,FaMYC2-like蛋白具有bHLH-MYC家族保守结构域。系统发育分析显示,FaMYC2-like蛋白与月季花(Rosa chinensis)等蔷薇科(Rosaceae)植物中的同源基因编码的蛋白质具有较近的亲缘关系。通过启动子顺式作用元件预测,发现其启动子区含有大量的光信号、胁迫响应及激素信号的响应元件。亚细胞定位结果表明,FaMYC2-like蛋白定位于细胞核中。组织特异性RT-qPCR结果显示,FaMYC2-like基因在草莓的根中表达量最高,在茎、叶和花中也有较高表达,在匍匐茎中表达量最低;在果实发育早期的小绿期和大绿期中表达量最高,在果实发育的中后期几乎不表达。低温、干旱和盐胁迫均能在早期显著诱导草莓根和叶中FaMYC2-like的表达。
