Archaeal communities in mineral soils were compared between a boreal forest in Finland and cold-temperate forest in Japan using 16S rRNA gene-targeted high-throughput sequencing. In boreal soils, Thaumarchaeota Group 1.1c archaea predominated and Thaumarchaeota Group 1.1a-associated and Group 1.1b archaea were also detected. In temperate soils, Thaumarchaeota Group 1.1a-associated and Group 1.1b archaea were dominant members at the subsurface, whereas their dominancy was replaced by Thermoplasmata archaea at the subsoil. An analysis of the ammonia monooxygenase subunit A gene of Archaea also indicated the distribution of Thaumarchaeota Group 1.1a-associated and Group 1.1b archaea in these soils.
