Aspects of archaeal diversity in peat soil samples from climatically and geographically distinct wetlands (subarctic: West Siberia Bog, Russia; temperate: Akaiyachi Mire, Japan; subtropical: Okefenokee Swamp, USA) were studied by molecular phylogenetic techniques. DNA was extracted directly from the soil samples and 16S rRNA genes were amplified by polymerase chain reaction. Partial sequences of the amplified 16S rDNAs (total 426 clones) were compared with known sequences from GenBank and the Ribosome Database Project (RDP). Peat-derived sequences were mostly related to Euryarchaeota, principally methanogens. Sets of sequences (operational taxonomic unit; OTU) were created for each wetland (21 OTUs for West Siberia; 22 OTUs for Akaiyachi; 33 OTUs for Okefenokee). The majority of the OTUs clustered in and showed low similarities to the Methanosarcinales family (West Siberia) or the Methanomicrobiales family (Akaiyachi and Okefenokee). In terms of the Shannon-Weaver diversity index, the archaeal community diversity in Okefenokee Swamp was greater than that of the other wetlands.
