The bacterial community structure in four geographically isolated arid regions on the Loess plateau, China, a source of Asian dust, was investigated using a 16S rRNA gene. Denaturing gradient gel electrophoresis and sequencing demonstrated that community diversity in the Loess plateau was low, and a common Alphaproteobacteria phylotype was identified. Phylogenetic analyses of arid soils revealed that most phylotypes had low similarity with known strains in various phyla, suggesting that these regions contain phylogenetically divergent and unknown bacteria.
利用 16S rRNA 基因对中国黄土高原四个地理位置隔离的干旱地区的细菌群落结构进行了研究。变性梯度凝胶电泳和测序表明，黄土高原的群落多样性较低，并且鉴定出了一个常见的α变形菌。干旱土壤的系统发育分析表明，大多数系统发育型与不同门的已知菌株的相似性较低，这表明这些地区含有系统发育上不同的未知细菌。
