Diversity and Distribution of Archaea Community along a Stratigraphic Permafrost Profile from Qinghai-Tibetan Plateau, China

Figure 3

DGGE of PCR-amplified archaeal 16S rRNA gene fragments from total community DNA from different depths (indicated above the lanes) in the soil profile. Marked DGGE bands were excised and sequenced. The numbers of DGGE bands correspond to the ones on the phylogenetic tree in Figure 4.
