Abstract

First report of Pantoea beijingensis induced soft rot disease of Pleurotus nebrodensis in China.

Abstract

In December 2009, soft rot disease appeared on fruiting bodies of Pleurotus nebrodensis in greenhouses located at Haidian district, Beijing, China. Early symptoms were water-soaked lesions on the pilei of the fruiting bodies. Lesions then spread and purulent tissues were formed. Severe soft rot induced production of deformed fruiting bodies and offensive odor. Diseased fruiting bodies stopped growth and commercial losses were estimated at 5-10%. The causal pathogen was identified as Pantoea beijingensis based on cultural, morphological, genetic and pathogenicity analyses. This is thought to be the first report of Pantoea beijingensis-induced soft rot disease of Pleurotus nebrodensis in China.
