Evaluation of pathogenicity variation between two <i>Erwinia</i> species in apples and their population using a duplex real-time PCR method.

ABSTRACT: Fire blight and black shoot blight diseases, caused by Erwinia amylovora and Erwinia pyrifoliae, respectively, continue to spread several areas in Korea, despite intensive efforts by the government to control diseases. The distribution pattern of fire blight and black shoot blight is different from each other in Korea. Consequently, it is required to investigate the pathogenicity of E. amylovora and E. pyrifoliae in apple trees. The disease severity of fire blight and black shoot blight was compared in this study by an artificial inoculation of E. amylovora and E. pyrifoliae suspensions into the abaxial veins of apple leaves and measuring their pathogenicity at varying temperatures. Furthermore, disease severity was assessed by inoculating E. am
