Fig. 2

Heat map of the expression levels of CPS, KS, KO, KAO, GA20ox and GA3ox genes in stem, flower, fruit and fruit pit. Red and green shading represent high and low expression levels, respectively. S1-S2, S3-S4 and S5-S6 represent combined samples of the internodes S1 and S2, S3 and S4, and S5 and S6. BP = bud period; RDP = red dot period; EP = equivalent in size between petal and sepal period; BFP = budding flower period; FBP = full bloom period. S3-I, S4-I, S4-II, and S4-III represent 118, 120, 122 and 124 d after full bloom, respectively. Pits were collected at 15, 25, 35, 45, and 55 days after full bloom
