摘要: A simple and efficient method was presented for isolating microsatellite DNA markers from peanut (Arachis hypogaea L) genome. The genomic DNA was converted into pre-amplified AFLP fragments and hybridized with biotin-labeled SSR probes. Then the hybrid mixture was used to incubate with magnetic beads coated with streptavidin. After washing to remove the non-SSR fragments, the eluted single-strand DNA, which was cloned and sequenced, was largely enriched for microsatellites. Primers can then be designed according to the sequence flanking the repeat motifs and used for polymorphism analysis. The whole experiment can be completed within one week and can be employed as a reliable option for any molecular laboratory to develop SSR markers.
