【摘要】 為分析刺芹側耳(Pleurotus eryngii)工廠化栽培中發(fā)黃腐爛子實體的細菌組成,構建16SrDNA文庫,利用限制性內切酶MspI和RsaI分別對隨機克隆進行酶切篩選,并測定代表性克隆16SrDNA序列,BLAST分析結果表明刺芹側耳子實體病狀組織中存有兩類菌群,分別為假單胞菌和芽孢桿菌屬。同時,對刺芹側耳子實體病狀組織中的細菌進行分離培養(yǎng)、致病性測定、16SrDNA鑒定及BLAST分析,病原細菌與惡臭假單胞菌(Pseudomonas putida)的同源性較高,其作為引起刺芹側耳工廠化栽培細菌性病害的病原菌在國內外尚屬首次報道。
【Abstract】 Rotted yellow fruit body tissue of Pleurotus eryngii obtained from an industrial mushroom cultivation facility was used to create a bacterial 16S rDNA library.Random clones were screened and obtained using the restriction endonucleases MspI and RsaI,and the 16S rDNA sequences of representative clones were identified.A BLAST search revealed the presence of two bacterial types in the disease tissue,which exhibited 97% and 93% similarity with Pseudomonas and Bacillus.Bacterial isolation and back in...
