中國栽培白靈側耳的RAPD和IGS分析
RAPD AND IGS ANALYSIS OF PLEUROTUS NEBRODENSIS CULTIVARS IN CHINA
張金霞 黃晨陽 張瑞穎 管桂萍
摘 要：以RAPD和IGS為分子標記,研究了中國栽培白靈側耳Pleurotus nebrodensis菌株的遺傳多樣性,RAPD結果表明,供試菌株間存在多態性;對供試菌株的IGS分析表明,白靈側耳P.nebrodensis的IGSl區域較保守,菌株間沒有多態性;IGS2區域進化較快,菌株間具豐富的多態性.IGS2-RFLP可應用于白靈側耳的菌株鑒定鑒別,較RAPD更穩定,更具可操作性.
關鍵詞：遺傳多樣性,菌株多態性,IGS2-RFLP
