  • 简介:蛋白质的表示得到或从Magnaporthe,在在米饭(OryzasativaL)激活抵抗的griesea和它的生物功能被报导。基因ofelicitor在Escherichia关口i房间被表示并且在SDS页上与42kDapparent分子量生产了His_6熔化蛋白质。净化的蛋白质能分别地导致抵抗到强风疾病,与在在强风接种以后的第14天和第21天的46.47%和36.41%的控制效率。同时,在有表示蛋白质,phenylalanineammonia-lyase(PAL)和过氧化物酶(邮政部门)的处理以后,活动在米饭植物被支持STKM,一度时髦的风尚,PBZ1和PR1基因的抄写层次在米饭植物被增加。而且在在二维的电气泳动胶化上比较全部的米饭叶蛋白质的侧面以后,大约14proteins被发现在表示蛋白质处理以后在表示水平被增加。Allthe结果显示表示蛋白质能是行动一elicit或在米饭触发抵抗。
