Overgrazing is an important driver of grassland ecosystem degradation and productivity decline.Plants and rhizosphere growth-promoting bacteria (PGPR) are highly effective synergism is one of the main ways for plants to effectively cope with stress and promote growth. Previous studies have found that under overgrazing stress, Leymus chinensis may regulate the synergistic effect with rhizosphere microorganisms through root secretions, so as to improve grazing tolerance. But does this synergy exist? How is it regulated? It studies relatively limited
