Abstract

Abstract: Root and stem rot caused by Phytophthora sojae is a devastating disease in soybean. It is necessary to understand the molecular interaction between P.sojae and host for pathogenic analysis and providing scientific basis for the management strategy. Current research shows that plant active its innate immune system based on a two-branched recognizes,and the identification of “non-me” molecules correctly is the essential step of the activation. Meanwhile,as for the pathogens,which inhibit plant immunity by cooperation within effectors repertoire,avoid host recognition through kinds of molecular strategies. In this review,we summarized how soybean Rps genes mediated race-specific resistance loss,and the strategies of P.sojae effectors escape and destroy the host immune response. We further discussed the possibility of novel resistance screening and accurate breeding based on these molecular interaction mechanism.

Key words: Soybean root and stem rot, P.sojae, effectors, molecular interaction
