【摘要】 以滇西北地區(qū)11個(gè)羊肚菌居群56個(gè)羊肚菌樣品為研究材料,應(yīng)用ISSR分子標(biāo)記方法,進(jìn)行了遺傳多樣性與親緣關(guān)系分析。結(jié)果表明,11個(gè)多態(tài)性ISSR引物對(duì)全部試驗(yàn)樣品進(jìn)行PCR擴(kuò)增,共獲得88條穩(wěn)定的條帶,其中多態(tài)性條帶70條(占79.55%)。應(yīng)用軟件POPGENE 32分析得出11個(gè)羊肚菌居群間遺傳距離的變化范圍在0.1715~0.4853之間,相似系數(shù)的變化范圍在0.6155~0.8424之間。遺傳分化分析表明,61.35%的變異存在于居群間,38.65%的變異存在于居群內(nèi)。對(duì)56個(gè)羊肚菌樣品進(jìn)行分子系統(tǒng)聚類分析(UPGMA)將資源分為三大組,對(duì)11個(gè)羊肚菌居群進(jìn)行親緣關(guān)系聚類分析將居群分為兩大類群,聚類結(jié)果與地理距離有明顯的相關(guān)性。
【Abstract】 11 Morchella populations,including 56 Morchella samples were used to detect the genetic diversity and relationship by inter-simple sequence repeats(ISSR) analysis.The results showed that 88 DNA fragments among all 56 Morchella samples were amplified,using 11 reliable ISSR primers,among which 70 DNA bands were polymorphic(PPB=79.55%).The obtained result by using POPGENE 32 software showed that genetic distance among 11 Morchella populations ranged from 0.1715 to 0.4853,and the genetic identity ra...
