First report of Diaporthe nobilis causing postharvest rot of blueberry in Shandong Province, China.
During June 2015, a postharvest fruit rot was observed on blueberry cv. Duke cultivated in Qingdao, Shandong, China, and stored for 7 days at 4°C after harvesting. Infected fruits showed soft and rotted lesions, covered with greyish or white mycelium under high humidity. The causal pathogen was isolated and identified as Diaporthe nobilis based on morphological, molecular and pathogenicity analyses. The obtained sequences were deposited in GenBank (accession nos. MG557846 for ITS, MG557847 for TUB, MG557848 for TEF1 and MG557849 for CAL). This is thought to be the first report of D. nobilis causing blueberry postharvest rot in China.
