文章简介由稻瘟菌引起的稻瘟病是水稻生产中最严重的真菌性病害。然而,稻瘟菌如何引起水稻细胞坏死,以及水稻如何抑制稻瘟菌从活体营养阶段转换到死体营养阶段的分子机制还不清楚。本研究发现,稻瘟菌侵染水稻时,效应蛋白Avr Piz-t可以招募水稻的转录因子APIP5。在水稻中抑制表达APIP5引起显著的细胞死亡表型,而Avr Piz-t则可以通过 Introduction The rice blast caused by Magnaporthe grisea is the most serious fungal disease in rice production. However, it is still unclear how rice blast cells cause cell necrosis in rice and how rice inhibits the transformation of rice blast from in-nutrition phase to dead-body nutrition phase. This study found that when the rice blast fungus infected rice, the effector protein Avr Piz-t can recruit rice transcription factor APIP5. Inhibition of the expression of APIP5 in rice caused a significant phenotype of cell death whereas Avr Piz-t was able to pass
