Evaluation on 20 Lentinula edodes Strains Using ISSR and F-MSAP Markers

  • 摘要: 利用简单序列重复区间扩增多态性(inter-simple sequence repeat,ISSR)和荧光标记甲基化敏感扩增多态性(fluorescence-labeled methylation-sensitive amplified polymorphism,F-MSAP)分子标记技术对收集到的20株香菇Lentinula edodes菌株进行遗传及甲基化多样性分析。ISSR结果表明,8对引物共可扩增出98条稳定清晰可辨的条带,其中多态性条带89条,多态性比率为90.82%,样品间的遗传相似系数范围为0.520 4~0.989 7。F-MSAP结果表明,15对引物共扩增产生13 487个CCGG位点。在全部检测位点中,半甲基化位点为1 704个,平均半甲基化率12.6%;全甲基化位点为1 865个,平均全甲基化率13.8%。进一步将MSAP数据分为甲基化敏感多态性(methylation sensitive polymorphism,MSP)和甲基化不敏感多态性(methylation insensitive polymorphism,MISP)。Mantel检测结果表明,ISSR与MISP分子标记的分析结果有显著的相关性,但ISSR与MSP分子标记的分析结果无显著相关性。说明香菇不同株系间广泛存在DNA甲基化多样性,在育种中具有重要的应用价值。
