Expression of Exogenous Anfimicrobial Peptide and Resistance to Stem Rot Disease of Houttuynia cordata Thunb.
摘要
Abstract
[ Objective ] This study was to identify the expression of exogenous antimicrobial peptide in transgenic Houttuynia cordata Thunb.plants, and analyze their resistance to stem rot disease. [ Method] SDS-PAGE and Western blot analysis were employed to detect expression of exogenous antimicrobial peptide in transgenic H. cordata plants. Both wild type and transgenic H. cordata plants were inoculated with different concentrations of Rhizoctonia solani spores for detecting their resistance. [ Result ] The exogenous antimicrobial peptide was detected at translation level. The optimal parameters for detecting the resistance of transgenic H. cordata plants to R. solani was inoculation of spores at a concentration of 3 x 105 ind./ml and cultured for three days. The results showed that resistance of transgenic H. cordata plants to R. solani was enhanced in comparison with CKs. [ Conclusion] Expression of exogenous antimicrobial peptide can enhance the resistance of transgenic H.cordata plants to stem rot disease.关键词
