semi-arid steppe Raw sequence reads. rhizosphere metagenome

our study demonstrated that long-term N addition had a profound influence on productivity of the steppe and composition of the rhizospheric microbial community of S. krylovii and A. frigida. This study highlight the importance of rhizospheric microbial communities in control and/or feedback of N addition-invoked steppe communities in response to N deposition. Our findings would contribute to our mechanistic understanding of impacts of N deposition on grassland ecosystem by linking changes in plant traits to their rhizospheric microbes-mediated processes.
