The MapMan Bin of differentially expressed genes showed that three genotypes behaved similarly in their transcriptional patterns. (A) Three representative ECMs used in the microarray analysis. M-33, RB-4, and SBT-6 were the representative ECMs of Marsh grapefruit, Star Ruby grapefruit, and Sunburst mandarin, respectively. (B) MapMan Bin of differentially expressed genes. Genes up/down-regulated more than 2-fold (ECMs/WTs, P < 0.05) are collected in RB and SBT, and more than 1.5-fold (ECMs/WTs, P < 0.05) are regarded as differentially expressed in M.
