【摘要】 以19個來源不同的茯苓栽培菌株為材料,采用MEGA4軟件對ITS序列進行NJ法聚類分析,構建系統發育樹。結果顯示,19個藥用茯苓菌株ITS長度為1 608 bp~1 611 bp,G/C含量在55.7%~59%之間,遺傳距離范圍為0~0.0636,遺傳差異不大,17個茯苓菌株組成1個大群,茯苓9號和茯苓5.545菌株各自單獨聚為一個群。 更多還原
【Abstract】 With the bio-software of MEGA4,the ITS sequences of 19 Poria cocos strains were studied using NJ method to construct the phylogenetic tree.Results showed that the ITS length,G/C contents,genetic distance of 19 Poria cocos strains ranged from 1 608 bp to 1 611 bp,55.7% to 59%,0 to 0.0636.17 Poria cocos strains were clustered into a greater group,and 9# strains and Fuling 5.545 were fallen into a separated group respectively. 更多還原
