Identification and characterization of Pestalotiopsis-like fungi related to grapevine diseases in China.

Pestalotiopsis -like fungi are an important plant pathogenic genus causing postharvest fruit rot and trunk diseases in grapevine in many countries. Pestalotiopsis -like fungi diseases were studied in vineyards in nine provinces across China. Multi-gene (ITS, β-tubulin and tef1 ) analysis coupled with morphology showed that a Neopestalotiopsis sp. and Pestalotiopsis trachicarpicola are associated in causing grapevine fruit rot and trunk diseases in China. Pestalotiopsis trachicarpicola is reported as the causative agent of grapevine diseases in the world for the first time. Neopestalotiopsis sp. caused significantly longer lesions than the other taxon present. This study represents the first attempt to identify and characterize the Pestalotiopsis -like fungi causing grapevine diseases in China using both morphological and molecular approaches.
