【摘要】 為分析刺芹側(cè)耳(Pleurotus eryngii)工廠化栽培中發(fā)黃腐爛子實(shí)體的細(xì)菌組成,構(gòu)建16SrDNA文庫,利用限制性內(nèi)切酶MspI和RsaI分別對隨機(jī)克隆進(jìn)行酶切篩選,并測定代表性克隆16SrDNA序列,BLAST分析結(jié)果表明刺芹側(cè)耳子實(shí)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(shí),對刺芹側(cè)耳子實(shí)體病狀組織中的細(xì)菌進(jìn)行分離培養(yǎng)、致病性測定、16SrDNA鑒定及BLAST分析,病原細(xì)菌與惡臭假單胞菌(Pseudomonas putida)的同源性較高,其作為引起刺芹側(cè)耳工廠化栽培細(xì)菌性病害的病原菌在國內(nèi)外尚屬首次報(bào)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...
