摘要:
细胞色素P450是一类重要的氧化酶,几乎参与植物所有的代谢途径,CYP72A属于CYP450的一个亚族,主要参与次生代谢及生物胁迫响应。以二穗短柄草(Brachypodium distachyon L.)基因组数据库为基础,利用生物信息学方法鉴定获得了14个CYP72A亚族成员。为鉴定二穗短柄草CYP72A亚族成员的功能,利用RT-qPCR方法分析CYP72A亚族基因在不同组织中及在禾谷镰刀菌处理下的表达模式。组织表达模式结果显示,在14个CYP72A亚族基因中,有7个基因在种子中的相对表达量较高,4个基因在叶片中的相对表达量较高。禾谷镰刀菌处理下的CYP72A亚族基因表达模式结果显示,有7个基因受禾谷镰刀菌诱导而上调表达,其中上调倍数超过8倍的有4个基因,分别是Bradi2g41110、Bradi2g44160、Bradi2g44190和Bradi2g44200,通过原生质体瞬时转化方法分析这4个CYP72A亚族成员的亚细胞定位,结果显示,4个CYP72A亚族成员都定位于内质网。综合以上研究结果可知,二穗短柄草CYP72A亚族基因在根、叶片中高表达,并且可能通过内膜系统参与生物胁迫响应。
