FIGURE 4.

Lotus japonicus root responses to non-adapted pathogenic bacteria and incompatible rhizobia. Venn diagram and heatmap representations of differential gene expression in the indicated conditions compared to H₂O controls. Significant gene expression differences were designated based on a fourfold change in expression with a FDR p-value ≤ 0.05. (A) Non-adapted pathogen Pst DC3000 induced differential gene expression. (B) Compatible symbiont Ml R7A compared to incompatible rhizobia Sf HH103 and Be USDA61 differential gene expression. For heatmaps, Log₂ fold change values were used.
