摘 要：The use of natural antagonistic microorganisms, such asPythium oligandrum, is a promising environmentally friendly approach to biologically control Pythium soft-rot disease of ginger(Zingiber officinale) caused by Pythium myriotylum.A critical part to improve the efficiency of biocontrol applications is to understand both the mechanisms of action of ***, and the mechanisms by which *** *** antagonism involves hydrolytic enzymes such as cellulases and proteases, and recently we uncovered a role for *** — produced volatile organic compounds in antagonism of *** effects of these mechanisms are obvious from major morphological and cytological damage to *** of the response of *** to *** proteases appears to involve upregulation of protease ***, in response to *** volatile compounds,*** initially showed a strong upregulation of putative detoxification-related genes that was not maintained at later ***, the responses of *** to *** suggest ways to reduce the ability of *** to defend against and counter-antagonise ***( e.g., by targeting *** protease inhibitors or detoxification genes), and thus improve the efficiency of ***-mediated ginger disease control.
