Distribution of differentially expressed genes (DEGs) of NaCl-treated plants at different time points.

<p>(A) The comparison of up-regulated and downregulated DEGs in different samples. The dark gray and light gray colors represented the up-regulated and downregulated DEGs in <i>S. europaea</i> root, respectively. The dark green and light green colors represented the up-regulated and downregulated DEGs in <i>S. europaea</i> shoot, respectively. The overlaps of the circles mean that the unigenes appeared in both of samples that the circles represent. (B) Clustering analysis of shoot and root samples treated with NaCl at different time intervals. Hierarchical clustering was conducted for the different time treated root and shoot samples based on DEGs in each sample.
