Cd-induced differential gene expression in leaves of two barley genotypes. Heat map visualises the expression of genes up-regulated in Weisuobuzhi and down-regulated and not changed in Dong17 (Cd vs control) after Cd exposure for 15 d. The contig IDs and annotations are listed on the right. Red, green and black indicate genes that increased, decreased and showed equal levels of expression, respectively, as compared to the control. The contig ID and annotation of each gene are listed on the right of the figure. The identity and accession numbers of genes are listed in Additional file 4: Table S3 and Additional file 5: Table S4.
