Effect of plant host type and irrigation treatment on root-associated metagenome. a VENN diagram of differentially-abundant genes between FW-irrigated tomato and lettuce (DESeq2 FDR p < 0.05). VENN diagrams of differentially-abundant genes by irrigation type in b tomato or c lettuce, and d in both hosts combined. e Canonical correspondence analysis (CCA) of all SEED-annotated genes with DOC, EC, and pH as constrained variables. f Microbial composition predicted by a least common ancestor (LCA) pipeline (MEGAN6) of the predicted gene catalogue. Taxonomic groups are displayed in the inner ring, and differentially abundant taxonomic groups between the two tested plant types are highlighted in the middle ring. The outer ring highlights the taxonomic groups that are significantly differentially abundant between irrigation treatments
