Plants impact structure and function of bacterial communities in Arctic soils

摘要

Microorganisms are prime drivers of ecosystem functions in the Arctic, and they are essential for vegetation succession. However, very little is known about the phylogenetic and functional diversities of the bacterial communities associated with Arctic plants, especially in low organic matter soils. Here, we studied the diversity and community structure of the total and diazotrophic bacterial communities in the rhizospheres of two Arctic pioneer plant species, Oxyria digyna and Saxifraga oppositifolia, as well as the phenotypic profiles of these communities.
