First report of Talaromyces funiculosus causing fruit core rot of peach (Prunus persica) in China.
In September 2017, inner brownish lesions and seeds covered by a greenish fungal mass were observed inside peach (Prunus persica) fruits (5% incidence) purchased from a local market in Fuzhou, China. Rotting was originating from the seed core without outer visible symptoms on the fruit. Based on morphological characteristics, molecular data (sequence analysis of the internal transcribed spacer regions and β-tubulin gene) and pathogenicity tests, the causal agent was identified as Talaromyces funiculosus. Previously, Alternaria spp. have been reported as a cause of core rot of peaches. This is thought to be the first report of T. funiculosus causing fruit core rot of peach worldwide. The core rot of peaches caused by T. funiculosus is a serious disease because it reduces fruit shelf life, cannot be detected prior to consumption, and can be confused with Penicillium postharvest decay.
