Fig. 8From: Genome-wide analysis of the apple CaCA superfamily reveals that MdCAX proteins are involved in the abiotic stress response as calcium transportersRelative expression analysis of MdCAX genes in apple under different abiotic stress conditions. The expression level was calculated with respect to control samples (0 h) with the 2—△△CT method. Bars at the right of each heat map shows the relative expression values of these MdCAX genesBack to article page
