Global analysis of the DEGs in rhizobia-inoculated and mycorrhized PvRbohB-RNAi roots. a Heatmap of all DEGs between PvRbohB-RNAi roots inoculated with R. tropici (Rhiz) or R. irregularis (Myc) compared to the noninoculated PvRbohB-RNAi roots. Number of total DEGs (b), upregulated DEGs (Up) (c), and downregulated DEGs (Down) (d) identified between the control and PvRbohB-RNAi roots under nodulation and mycorrhization conditions. Venn diagrams show the intersections between the upregulated and downregulated DEGs shared between the nodulation (e) and mycorrhization (f) processes in control and silenced roots. A cutoff threshold of Log2FC ≥ 1.5 and P-adj/FDR ≤ 0.05 was used
