Relationship between microbial diversity and nitrogenase activity of Stipagrostis pennata rhizosheath

Nitrogen is the key factor for plant survival and growth, especially in the desert. Stipagrostis pennata , a sand born drought‐resistant plant, could colonize pioneerly in Gurbantunggut Desert during revegetation. One strategy for their environment adaptation was the rhizosheath formatted by root‐hair, mucilaginous exudates, microbial components, and soil particles, for which not only provides a favorable living microenvironment but also...
