Archaeal Diversity and the Prevalence of Crenarchaeota in Salt Marsh Sediments

摘要

Crenarchaeal 16S rRNA sequences constituted over 70% of the archaeal clones recovered from three salt marsh sites dominated by different grasses. Group I.1a Crenarchaeota dominated at two sites, while group I.3b Crenarchaeota sequences were most abundant at a third site. Abundances of 16S rRNA genes related to “Candidatus Nitrosopumilus maritimus” differed by site and sampling date.
