Grazing intensity rather than host plants palatability shape the community of arbuscular mycorrhizal fungi in a steppe grassland

The objective of this study was to elucidate whether AMF communities in the root and rhizosphere soil of two dominant perennial grasses in steppe grasslands in North of China (Leymus chinense (Trin.) Tzvel. and Stipa grandis P. Smirn) shifted in response to grazing intensity. L. chinense is highly mycorrhizal and a palatable bunch grass while S. grandis exhibits less mycorrhizal colonization and has a low palatability.
