FIGURE 2.

Lotus japonicus tissue-specific responses to compatible M. loti R7A and Nod factor. Venn diagram and heatmap representation 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) R7A induced gene expression in whole roots and root hairs. (B) NF-dependency of early root hair differential gene expression. (C) R7A induced gene expression in nodule primordia and mature nodules compared to whole roots. For heatmaps, Log₂ fold change values were used. NF, Nod factor; RH, root hairs.
