摘要 香菇(Lentinula edodes)是世界主要栽培食用菌之一,香菇菌种的准确鉴定是香菇大规模生产和菌种知识产权保护的重要前提。本研究基于香菇全基因组序列开发200对SSR标记用于25份常用香菇栽培菌种的遗传多样性分析和菌种鉴定。结果表明:供试材料的遗传相似性较高,遗传相似系数平均值为0.776,最小值为0.567,最大值为1。基于遗传多样性分析结果,筛选出7对带型清晰且重复性好的SSR标记,并成功构建了11份香菇商业菌种的多位点SSR指纹图谱。这11份菌种分别为:Cr-02、闵丰1号、香菇241-4、森源1号、森源8404、香九、广香51号、华香5号、L952、L9319、L808。 Lentinula edodes is an important cultivated mushroom in China,and accurate and reliable identification of individual cultivars is a prerequisite for successful cultivation and variety protection.In this study,the whole genome sequence of L.edodes was used to generate 200 simple sequence repeat(SSR)markers for delineating 25 commercial cultivars and for determining their genetic diversity.Our data revealed a relatively high level of genetic similarity among the cultivars,with average,minimum and maximum genetic similarity coefficient values of 0.776,0.567 and 1.000,respectively.Seven SSR primer pairs delineated eleven of the cultivars(Cr-02,Minfeng-1,Xianggu 241-4,Senyuan-1,Senyuan-8404,Xiang-9,Guangxiang-51,Huaxiang-5,L952,L9319 and L808)based on their unique multilocus SSR fingerprint profiles.
