DNA 标记技术在螨类系统学研究中的应用.

For a long time, mites mainly rely on the morphological characteristics in the systematic study. DNA markers are DNA fragments which can reflect the characteristics of the genome between individual species or species. Recently, the application of DNA markers has become more and more important in the systematic study of mites. The present situation and prospect of DNA markers, RAPD (Random Amplified Polymorphic), RFLP (Restriction Fragment Length Polymorphism), SSR (Simple Sequence Repeat), DNA Sequence Analysis, AFLP (Amplified Fragment Length Polymorphism) and DALP (Direct Amplification of Length Polymorphism), used in the systematic study of mites are described here, which will be helpful for research on acarolog [ABSTRACT FROM AUTHOR]
