Molecular mechanism of soybean to Phytophthora root rot

Phytophthora root rot is one of the most destructive diseases of soybean.Sharing economic loss of soybean industry is caused by Phytophthora root rot of soybean every year.Selecting,breeding and planting of resistant cultivars are one of the effective methods to control Phytophthora root rot of soybean.Resistance mecha-nisms is the theoretic base of selecting and breeding of resistant cultivars,so resistance mechanism of Phytoph-thora root rot is focused on in the world.According to research progress of Phytophthora root rot,this paper briefly presented the progress on the defense genes of soybean,avirulence gene of Phytophthora sojae and inter-action of soybean-Phytophthora sojae.
