Carbohydrate active enzymes protein (CAZymes),one large kind of important proteins of plant pathogenic fungi and bacteria,plays an important role in its growth and development. Trichoderma virens Gv29-8 is the important bio-control agent of Trichoderma ssp.,inhibiting many plant pathogens. Predicting and analyzing the characteristics of the CAZymes is of great significance. Based on 377 secreted proteins obtained preliminary data,CAZymes protein was predicted with CAT forecasting procedures. 185 CAZymes proteins were found in T. virens Gv29-8 and divided into major categories and composite category. The former includes 71 GHs,54 CBMs,12 AAs,25 CEs,3 PLs and 3 GTs; the latter includes 17 CAZymes proteins. Genetic analyses showed that CAZymes classification should be further refined to a smaller category. It will lay a solid theoretical foundation for further studying its function.
