Distribution and diversity of archaeal communities in selected Chinese soils

Peng Cao, Li-Mei Zhang, Ju-Pei Shen, Yuan-Ming Zheng, Hong J Di, Ji-Zheng He



To understand the distribution and diversity of archaea in Chinese soils, the archaeal communities in a series of topsoils and soil profiles were investigated using quantitative PCR, T-RFLP combining sequencing methods. Archaeal 16S rRNA gene copy numbers, ranging from 4.96 × 10(6) to 1.30 × 10(8)  copies g(-1) dry soil, were positively correlated with soil pH, organic carbon and total nitrogen in the topsoils. In the soil profiles, archaeal abundance was positively correlated with soil pH but negatively with depth profile. The relative abundance of archaea in the prokaryotes (sum of bacteria and archaea) ranged from 0.20% to 9.26% and tended to increase along the depth profile. T-RFLP and..
