Differentially-expressed miRNA genes in the root and shoot. (A) The number of genes up- or down-regulated by Cd treatment by >2-fold in root and shoot (P < 0.05); (B) A Venn diagrams showing the unique and shared regulated miRNA genes in the rice root and shoot under Cd stress; (C) Hierarchical cluster analysis of 17 miRNA genes that are regulated in both the root and shoot. The relative fold-changes were analyzed. The fold-change ratios of the genes are indicated by the different colors.
