摘要: DNA of Sharaia bambuiscola was extracted by the improved method of CTAB. The several key factors affecting the effect of DNA digestion and the PCR selective amplification such as the time of DNA digestion, the times of the per-amplified dilute products, the mount of the selective amplification primer, Taq concentration and dNTPs concentration were optimized and trialed with establishment of an optimized AFLP reaction system of S. bambusicola. The best time of digestion DNA with double endonucleases (EcoR I and Mse I) was 3h. The optimized selection amplification system was 25 mu l reaction mix containing 2.5 mu l the 20 times of the per-amplified dilute products, 2.5 mu L 10x buffer(with Mg2+), 10mmol/L primer each 1.5 mu L, 2.5U.mu L-1 Taq polymerase 0.7 mu L, 10mmol/L dNTP 0.5 mu L, and 15.8 mu L ddH(2)O. Stable and clean DNA finger print can be obtained and 3 pairs of AFLP primers with good genetic diversity were selected according to the optimized reaction system. The results will be an effective protocol for further studying the genetic stucture and differentiation, phylogenetic trees, host specificity and artificial cultivation of Shiraia bambusicola population.
