Variation in the structure of microbial communities associated with different alfalfa (<i>Medicago sativa</i> L.) cultivars.

ABSTRACT: The rhizosphere is a critical zone for root-soil-microbe interactions, and plant species play a major role in shaping its microbial community structure. Alfalfa (Medicago sativa L.), a widely cultivated forage crop with high nutritional and economic value, serves as an ideal model for studying cultivar-specific rhizosphere microbiomes. Using high-throughput sequencing, this study aimed to analyze the rhizosphere microbial communities of seven alfalfa cultivars. A total of 27,878 bacterial OTUs and 5,380 fungal OTUs were identified across all samples. The dominant microbial phyla included Actinobacteria and Proteobacteria (bacteria) as well as Ascomycota (fungi). Although the overall microbial community composition was broadly similar across cultivars, some subtle differences were ob
