Variation of DEGs for each alfalfa cultivar inoculated with two different rhizobial strains. a DEGs detected in biotype vs. CK comparisons. Number of upregulated (top) and downregulated (down) genes is indicated within each column. Data are means and standard errors of three biological replicates. b DEGs detected in biotype comparisons; c A Venn diagram of DEGs in biotype comparisons; **P < 0.01; E2, Effective two-cultivars specific biotype; E1, Effective one-cultivar specific biotype; CK, uninoculated control; G9, M. sativa cv. Gannong No. 9; G3, M. sativa cv. Gannong No. 3; Q, M. sativa cv. Qingshui; L, M. sativa cv. Longzhong
