Abstract:
A new method of identification and study of diversity of endophytes wa s described in this paper. The seedlings of tomato were treated using four meth o ds, sterile water, chemical reagents, ultraviolet radiation and mechanical to pe el off, respectively. Then endophytes were isolated using plates of beef- pept on e, Gaos I and PDA respectively. The optimal method of wiping off non-endophyte s was determined. We had obtained 148 isolates of endophytes with different size, shape and color. 43 strains of 148 were amplified using method of ERIC-PCR. T he results showed that 32 strains with amplified bands could fall into 28 classes. The purified bacteria were cultured confronting to leaf blight pathogen of tomat o to screen high resistant strain. Three bacteria strains with high resistance to pathogen were obtained.
