A high-throughput DNA sequencing method that generated high quality data was developed. A frame fashioned from a standard agarose gel combined with 0.1%–0.2% low-melting point (LMP) agarose gel was used to isolate the PCR product of interest. Collected PCR products were centrifuged without any reagents and the supernatants were directly used for a sequenc- ing reaction. This method is simple and labor efficient, provides high quality sequences at a low cost, and bypasses problems with impure PCR products. This technique has been used for single nucleotide polymorphism (SNP) discovery in Populus angustifolia trees.
