KEGG pathway enrichment and schematic diagram of hormone-related genes involved in drought stress tolerance. (A) DEGs detected under different conditions were analyzed by KEGG mapper, and enrichment was performed by hypergeometric probability distribution. Pathways with p<0.01 and FDR<0.05 are shown. 1 and 2: pathways commonly involved in drought stress response and drought tolerance after P. indica colonization; 3-6: pathways specific to DEG sets as denoted in the figure. (B) Schematic diagram of hormone–related genes involved in drought stress tolerance based on KEGG mapping of hormone-related DEGs, relative knowledge documented in reference (detailed annotation and expression pattern of each gene is found in the supplemental tables).
