Figure 2.

Relative expression levels of LjPINs in root nodules 20 dpi in comparison to the nodules 54 dpi. The expression values for nodules 54 days post rhizobial inoculation (dpi) were set as unity for each tested gene and the expression level in nodules 20 dpi was proportionally converted. Mean values (±SE) are derived from three biological replicates, for which three individual qPCR reactions were performed (n = 9). Asterisks above the bars represent statistically significant difference at the level p < 0.01 (**) or p < 0.001 (***).
