By combining asymmetric PCR and overlap extension, we developed a novel asymmetric overlap extension PCR (AOE-PCR) method for site-directed mutagenesis which bypassed the need for intermediate purification and excluded the amplification of a wild-type template. This method was used to introduce single base mutations into a small GTPase gene from cotton and to simultaneously introduce two mutations just by repeating this method using the first round AOE-PCR products as template. Our results suggested that the AOE-PCR method represents a valuable improvement of the original overlap extension PCR for site-directed mutagenesis.
