Research advance on the resistant mechanism of cotton against Verticillium Wilt

In this paper, the hereditary characteristic and the resistant mechanis m of cotton against Verticillium wilt, such as the identification of the pathoge n to host, tissue resistance, physiological and biochemical resistance, ecologic al resistance were reviewed. The results showed that the fungal elicitor was the key factor of host and pathogen making each other. The inherent and inducible tissue structure resistance of different cotton plants resist to Verticillium wi lt was diverse. The relation of antitoxin, enzyme, saccharide, hormone and cotto n disease resistant in physiological biochemistry resistance was reviewed, the e cology resistance of the cotton to Verticillium wilt that was the effect of cott on root system secretion and root system microorganism with the Verticillium wil t was explained. Among of them, although the physiological biochemistry resistan ce is the dominant effect, it is related to the effect of other mechanism. In addition, the progress of molecular breeding of cotton resist to the Verticillium wilt, the application of molecule marker technology such as RFLP, RAPD, AFLP, SSR etc. and transgenic technology in the molecule breeding were given. Finally, the priority in resistant mechanism and the molecular breeding of cotton resisted to the Verticillium wilt in the future were prospected.
