We describe a two-step PCR strategy using tagged highly degenerate primer (THDP-PCR) targeting copper-containing membrane-bound monooxygenases (CuMMO) genes for community analysis of methane- or ammonia-oxidizing bacteria. This strategy consists of a primary CuMMO gene-specific PCR followed by a secondary PCR with a tag as a single primer. This strategy remarkably increases the divergence of CuMMO gene amplicons while maintaining PCR efficiency without obvious amplification bias. This THDP-PCR strategy can be extended to other functional gene-based community analysis with design of new highly degenerate primer covering target functional gene sequences.
