Abstract:

The control effects of the extra cellular antimicrobial proteins (EACP) on the capsicum anthracnoses were 81.82% and 52.00% after 9 d and 13 d respectively. The physiological and biochemical mechanism of the EACP from strain CIII-1 controlling anthracnoses of pepper showed that: compared with the treatment inoculating the sterile water, the treatment inoculating EACP did not remarkably change the contents of the soluble protein and MDA and activities of SOD. The activities of POD, PPO and PAL of capsicum were all improved obviously after being treated with EACP, but the basal trends are not the same. Antimicrobial proteins isolation from strain CIII-1 can enhance anti-disease capability of plants by inducing antidisease enzyme activation.
