摘要:
花生(Arachis hypogaea)是我国的主要油料作物,花生油脂的合成受3-磷酸甘油酰基转移酶(GPAT)调控,但其调控机制尚不清楚。从花生中克隆了13个GPAT基因,编码含有4个酰基转移酶保守结构域的蛋白;同时,运用酵母遗传互补体系对基因功能进行了鉴定。在该体系中,酵母双突变体菌株ZAFU1(Δgat1gat2)因缺少GPAT而不能在特定的葡萄糖培养基上生长。结果表明,AhGPAT1/2/3/6/9与空白载体一样,其导入并不能恢复酵母双突变体ZAFU1在葡萄糖中的生长缺陷,而AhGPAT5B、AhGPAT7A/B的导入能恢复酵母双突变体ZAFU1在葡萄糖中的生长缺陷,说明上述3个基因具有酰基转移酶活性,从而为进一步研究花生油脂的合成代谢调控提供了参考。
