An emerging pathogen from rotten chestnut in China: Gnomoniopsis daii sp. nov.
Forests 10 (11 - 1016)
Abstract: Nut quality is fundamental to the economic viability of the Chinese sweet chestnut industry, but fruit rot disease significantly reduces this quality. In this study, we investigated chestnut rot in Anhui and Hubei provinces in China. Typical brown rot symptoms were observed, affecting nuts from different plantations. Isolates were obtained from symptomatic tissues of rotten fruits that were identified based on morphological comparison and phylogenetic analyses of partial internal transcribed spacer (ITS), and tef1 and tub2 gene sequences. The inoculation results showed that the tested fungal species is pathogenic to chestnut fruits. Hence, a new and severe pathogen that causes Chinese sweet chestnut brown rot, Gnomoniopsis daii sp. nov., is introduced herein.
