【中文摘要】 近年來褐斑病給我國平菇生產造成的損失日益嚴重。其癥狀主要表現為菌蓋表面出現褐色斑點;如果濕度過高,菌蓋表面能形成菌膿;如果感染原基或幼菇,會導致子實體畸形或停止發育。從病斑組織分離出病原細菌T3,根據Biolog自動鑒定系統鑒定結果、16S rDNA序列分析以及嵌套PCR檢測結果進行了綜合鑒定,確認該病原細菌為Pseudomonas tolaasii。

【英文摘要】 In resent years,significant loss of Pleurotus ostreatus which is one of most important commercially cultivated mushrooms was caused by the brown blotch disease in China.Brown blotch on pileus was formed.If humudity was higher enougy,fungal concerntration could be formed on pileus.If primordium or young fruitbody were infected,it would be malformed fruiting body or stunt.The bacteria isolated from the brown blotch was designated T3.So T3 was identified as P.talaasii on the results of Bilong system,16 SrDNA sequence analysis and nested PCR.
