| 中文摘要: |
| 以侧耳属Pleurotus15个种的15个菌株为材料，根据GenBank上侧耳属细胞色素c氧化酶亚基Ⅰ基因（cytochrome c oxidase subunit 1 gene，CO1）序列信息，设计引物CO332F、CO332R，进行第一轮PCR扩增，结果显示所有菌株都能得到单一条带，根据条带大小，15个菌株可分为4组。随后针对每个种设计特异性引物，进行第二轮PCR扩增，结果显示每个菌株只有在自己特异的引物中出现目的条带。通过两轮扩增，根据扩增条带的大小和有无，即可对15个种进行快速鉴定。 |
| 英文摘要: |
| 15 strains belonging to 15 species of Pleurotus were used. Primer CO332F and CO332R were designed by the cytochrome c oxidase subunit 1 gene (CO1) sequence of Pleurotus downloaded from GenBank. Results of the first-step PCR amplification showed that all the strains can get one band. The 15 strains were divided into four groups by the band size. Species-specific primers were designed accordingly. Results of the second-step PCR amplification showed that each species can get one band by the species-specific primers. In conclusion, the 15 species of Pleurotus can be identified by two-step PCR in accordance with the band size and the presence or absence of the band. |
