Comparative analysis of actinorhizal nodule and associated soil microorganism diversity and structure in three <i>Alnus</i> species.

ABSTRACT:

Background

Due to the importance of biological nitrogen fixation in terrestrial ecosystems, actinorhizal symbiosis has attracted more and more attention. Alders (Alnus) are important actinorhizal plants, but little is known about the diversity of symbiotic microbiota in the actinorhizal nodules. In addition, it remains unclear about the influence of the host species and habitats on the microbial community of alder root nodules and rhizospheric soils.

Methods

In this study we sequenced the hyper-variable regions of the 16S rRNA from the root nodules and their rhizosphere soils of three alder species (Alnus mandshurica, A. sibirica, A. japonica) in northeastern China to explore the diversity, composition, network association, and nitrogen cycling pa
