Schematic of physiological and metabolic data related to bayberry fruit taste during ripening. (A) Changes in TSS, pH, content of soluble sugars, and content of organic acids, (B) Sucrose metabolism and organic acid degradation through the GABA shunt. Enzyme names, UniGene ids and expression patterns are indicated at the side of each step. The expression patterns of each UniGene are shown by 4 grids, with the left one representing the RPKM value at 75 DAF, and the second to fourth ones from the left to the right representing the relative log2 (expression ratio) at 75, 80, 85 DAF, respectively. The grids with 10 different colors from blue to red show the absolute expression magnitude at 75 DAF, with the RPKM values 0-10, 10-20, 20-40, 40-80, 80-160, 160-320, 320-640, 640-1280, 1280-2560, and over 2560 represented by color 1 to 10, respectively.
