Abstract
Leaf spot diseases occur widely and pose serious impacts on peach production in China. In this study, 60 symptomatic leaf samples were collected from seven provinces in China. Diseased samples were plated on nutrient agar and sucrose-peptone-agar media and purified colonies were identified as Xanthomonas arboricola pv. pruni (Xap) based on morphological features, molecular identification and pathogenicity test. Hypersensitive response and pathogenicity tests were conducted on inoculated tobacco and peach seedlings. Phylogenetic analysis of 16S rRNA gene sequences indicated that the Xap isolates clustered together with Korean, Japan and Taiwan isolates. This is the first report of bacterial leaf spot caused by Xap on peach in China.
