【摘要】 采用FIASCO方法,從糙皮側(cè)耳(Pleurotus ostreatus)菌株ACCC 50838分離簡(jiǎn)單重復(fù)序列分子標(biāo)記(Simple sequence repeat,SSR),所得標(biāo)記用于分析我國(guó)52個(gè)側(cè)耳(平菇)栽培菌株多樣性,對(duì)于SSR標(biāo)記相同的菌株再進(jìn)行ISSR PCR分析。結(jié)果表明:18個(gè)SSR標(biāo)記在供試菌株中的等位基因的數(shù)量為3~12個(gè),多態(tài)性指數(shù)(PIC)為0.34~0.84;除了2組(ACCC50618,ACCC 50866和ACCC 50915;ACCC 50249和ACCC50476)共5個(gè)菌株之外,其他47個(gè)菌株都能利用這18個(gè)SSR標(biāo)記進(jìn)行有效的鑒別。SSR標(biāo)記相同的的菌株,其ISSR、體細(xì)胞不親合性和出菇性狀(溫型、菌蓋顏色)也相同,這些菌株可能是同物異名。利用這18個(gè)SSR標(biāo)記分析52個(gè)菌株的遺傳多樣性,相似性指數(shù)為0.755~0.9995。根據(jù)相似性指數(shù)進(jìn)行聚類分析,52個(gè)菌株分成兩個(gè)大的類群,分別為糙皮側(cè)耳(P.ostreatus)和肺形側(cè)耳(P.pulmonarius)。結(jié)合這些栽培菌株的農(nóng)藝性狀和SSR分子標(biāo)記的聚類分析結(jié)果,我國(guó)平菇栽培菌株的遺傳...
【Abstract】 Oyster mushrooms represent one of the most important groups of commercially cultivated edible mushrooms worldwide.In this study,18 novel polymorphic simple sequence repeat(SSR) markers were developed and characterized from Pleurotus ostreatus,strain ACCC 50838.The number of alleles detected for each SSR locus varied between three and twelve across the 52 oyster mushroom cultivars,48 of which were previously designated as P.ostreatus and four as P.pulmonarius.The polymorphism information content(...
