is an important pathogen that infects various herbaceous perennials and reduces their economic value. In this study, we examined isolates carrying a virulence gene from symptomatic lily plants grown in South Korea. Phylogenetic analysis using the nucleotide sequences of 16S rRNA, , and led to the classification of the isolates into four different strains of . Inoculation of with these isolates slowed root growth and resulted in symptoms of leafy gall. These findings elucidate the diversification of domestic pathogenic and may lead to an accurate causal diagnosis to help reduce economic losses in the bulb market.
