Archaeal amo A gene diversity points to distinct biogeography of ammonia‐oxidizing Crenarchaeota in the ocean
Summary Mesophilic ammonia‐oxidizing Archaea (AOA) are abundant in a diverse range of marine environments, including the deep ocean, as revealed by the quantification of the archaeal amo A gene encoding the alpha‐subunit of the ammonia monooxygenase. Using two different amo A primer sets, two distin...
