Genetic Diversity of Antagonistic Endophytic Bacteria Isolated from Amorphophallus konjac

Endophytic bacteria living in Amorphophallus konjac have the potential of antagonistic bacterial pathogen activity against the Amorphophallus soft rot pathogen Erwinia carotovora subsp carotovora (Ecc). The paper was to study and analyze the genetic diversity of 35 endophytic bacteria isolated from A. konjac with strong antagonistic effect against to Ecc. Using total DNA sequence Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR) method, a total of 35 endophytic bacteria were carried out genetic diversity analysis. ERIC-PCR fingerprint map showed that 35 endophytic bacteria were divided into 4 ERIC groups and 4 strains with independent groups at Watson distance of 0.60. The results showed that the genetic diversity of 35 antagonistic strains was obvious.
