| 摘 要： | 为从线粒体角度了解银耳(Tremella fuciformis)主要栽培菌株的遗传多样性,从37个银耳栽培菌株中选取33、34和37号3个典型菌株进行高通量基因组测序,并进行线粒体基因组组装和分析,结果表明:3个菌株的线粒体基因组序列一致,但就线粒体基因组拷贝数而言,33号显著高于34号、37号.选取37号菌株线粒体基...

| Abstract: | Mitochondrial DNA diversity of major cultivated strains of Tremella fuciformis was studied.Using high-throughput sequencing,three certificated cultivars of T.fuciformis,strain No.33,No.34 and No.37,were subjected to whole genome sequencing.Then their mitochondrial genome sequences were assembled and analyzed.The results showed that strain No.33,34 and 37 were identical in mitochondrial genome sequence,but the DNA copy number of strain No.33 was greater than that of strain No.34 and No.37.Analysis of mitochondrial intron polymorphism in strain No.37 and seven previously published wild type strains showed a rich diversity in number of introns and insertion positions between these strains.Using eight pairs of primers specific to the mitochondrial genome of strain No.37,PCR analyses were carried out on 36 cultivated strains.For all the primers,there was a band with the same length as predicted in strain No.37 in all 36 strains,suggesting all 36 strains contained the same intron as strain No.37. |
