Abstract:
Genetic diversity among different strains were researched by analyzing the morphological characters and ITS sequence of 44 Auricularia auricular strains from Qinba Mountains.Using CTAB method to extract genomic DNA,amplifying and sequencing PCR products.The software CluatalX and MEGA 5.0 were applied to sequence alignment and phylogeny analysis.The results showed that plentiful genetic diversity among different strains was found,while the homology of parts of Auricularia auricular strains was high.Based on the similarity coefficient about 0.002,the strains were separated into five groups.The genetic relationship between Auricularia auricula-judae 268 and others were quite far.
