Expression differences in conserved miRNAs between libraries constructed from salt-treated and untreated tissues. (A) The salt-treated leaf (3dSL) and control leaf (3dCKL) libraries. (B) The salt-treated root (3dSR) and control root (3dSR) libraries. (C) The control root (3dCKR) and control leaf (3dCKL) libraries. (D) The salt-treated leaf (3dSL) and salt-treated root (3dSR) libraries. Each point in the figure represents a miRNA; the x- and y-axes represent the miRNA expression levels in the two samples; red represents miRNAs with ratios >2; blue represents miRNAs with ratios ≥½ and ≤2; green represents miRNAs with ratios <½; ratios are the normalized expression in the salt-treated sample:normalized expression in the control sample.
