| 中文摘要: |
| 甲螨是一类重要的土壤动物，体型微小，一般具有较厚的体壁。本研究针对甲螨这一特定类群，探讨了一种无形态特征损伤的DNA提取技术。通过结合试剂盒DNA提取法，并适当改进实验条件，设计出一套行之有效的DNA提取流程。通过对提取DNA之后的标本进行形态学观察，发现其主要的分类学特征均保存完好，可以作为凭证标本长期保存。本研究所提供的DNA提取技术既可以提取出足够的DNA又可以保留凭证标本，因此能有效促进甲螨分子分类学相关研究。 |
| 英文摘要: |
| Oribatid mites are of great significance in soil ecological system. They are small (0.1~1 mm) and usually sclerotized heavily. This research provided an efficient and non-destructive DNA extraction method for oribatid mites. By changing the method of DNA extraction and using DNeasy blood and tissue kit, a new method for DNA extraction without destroying morphological features could be applied to oribatid mites. The morphological characters valuable for identifying the specimens had not been destroyed after DNA extraction with this method, and the voucher specimen could be kept for further studies. This method could not only obtain high quality DNA templates but also keep voucher specimen. It could be an efficient way to help DNA taxonomy on oribatid mites. |
