Mangifera indica L.is one of the well-known fruits in China.Bacterial diseases have been occurring seriously in recent years.A bacterial necrotic disease mixed with bacterial black spot disease on mango was observed,with an incidence rate of 30％-60％,even up to 90％,in our investigation of mango diseases in Baise,Guangxi from 2020 to 2021.Twenty-one isolates belonging to the genus Pantoea were successively isolated from the mango necrotic tissues in investigation region in this study.The isolates were identified as four species:Pantoea vagans,P.anthophila,P.dispersa and P.cypripedii based on the morphological,physio-biochemical characteristics,16S rDNA sequence,phylogenetic analysis of fusA-gyrB-leuS-pyrG-rlpB-rpoB concatenated sequences and pathogenicity test.This is the first report of necrotic disease caused by P.anthophila,P.dispersa and P.cypripedii in mango in China.
