油菜的生长发育受病害、干旱、高盐和低温等逆境胁迫的影响较大。油菜植株中很多被上述胁迫诱导而表达的基因,如产物能直接增强油菜对逆境抗性的功能基因,和产物为转录因子而作为信号转导调控其它基因的表达而间接提高抗性的调控基因。很多转录因子涉及到油菜逆境抗性,AP2/ERF是其中重要的一个家族。目前通过不同方法从不同种类的油菜中共克隆了24个AP2/ERF家族转录因子,属于ERF和DREB/CBF亚族。这些基因分别能够被低温、干旱、高盐、乙烯、ABA和茉莉酮酸酯诱导,并启动油菜中一些相关下游基因的表达,从而增强油菜的抗逆性能。本文综述了油菜中AP2/ERF家族转录因子的克隆、进化关系分析、空间结构及生物学功能。
Rape growth and development by disease, drought, high salt and low temperature stress greater impact. Many of the genes in Brassica napus plants that are induced by the stress mentioned above, such as the functional genes whose products can directly enhance the resistance of adversity to rapeseed and the genes whose transcriptional products act as signal transducers and indirectly regulate the expression of other genes, . Many transcription factors are involved in adversarial resistance to rapeseed, AP2 / ERF is one of the important families. At present, 24 AP2 / ERF family transcription factors are co-cloned from different species of rapeseed by different methods and belong to the ERF and DREB / CBF subfamilies. These genes can be induced by hypothermia, drought, high salt, ethylene, ABA and jasmonate respectively, and initiate the expression of some related downstream genes in rapeseed so as to enhance the resistance of rapeseed. This review summarizes the cloning, evolutionary relationships, spatial structure and biological functions of AP2 / ERF family members in rapeseed.
