title: Identification of walnut (Juglans regia) leaf spot agent by its production of species-specific phytotoxin
abstract: Aim. For the purpose of correct species and internal identification of isolated strains of bacteria that cause walnut leaf spotting, molecular biological and genetic detection of their ability to synthesize the phytotoxin syringomycin have been carried out. Methods. It has been used microbiological and molecular genetic (PCR) methods. Results. The presence of syringomycin (syrD) phytotoxin secretion genes was established in isolated strains of walnut leaf spot pathogen and the typical strain of
