摘要
Although the richness of Bacteria and Fungi in Cerrado' soils has been reported, here we report, for the first time, the archaeal community in Cerrado's soils. DNA extracted from soil of two distinct vegetation types, a dense subtype of sensu strict (cerrado denso) and riverbank forest (mata de galeria), was used to amplify Archaea-specific 16S rRNA gene. All of the fragments sequenced were classified as Archaea into the phylum Thaumarchaeota, predominantly affiliated to groups I.1b and I.1c. Sequences affiliated to the group I.1a were found only in the soil from riverbank forest. Soils from 'cerrado denso' had greater Archaea richness than those from 'mata de galeria' based on the richness indexes and on the rarefaction curve. beta-Diversity analysis showed significant differences between the sequences from the two soil areas studied because of their different thaumarchaeal group composition. These results provide information about the third domain of life from Cerrado soils.
