FIGURE 2.

Expression profile of genes encoding orthologs of Nod factor receptors, and of genes encoding homologs of proteins linked to infection thread growth in legumes, in roots and nodules of D. glomerata (A) and C. thyrsiflorus (B). Gene expression levels in roots (R) and nodules (N) are given relative to those of EF-1α. The median and interquartile range (IQR) of at least three biological replicates are shown. Differences between R and N are indicated at ^∗∗p < 0.01, ^∗p < 0.05 after student’s t-test followed by FDR multi comparison correction. Y-axis is given in log₁₀ scale.
