Fig. 1

Color data of adaxial and abaxial surfaces of Ananas comosus var. bracteatus chimera leaves. a CIE color values and coordinate flats of the adaxial surfaces of GR and RE samples. The GR circle represents L^* = 46, a^* = −5, and b^* = 15; and the RE circle represents L^* = 68, a^* = 23, and b^* = 16. b CIE color values and coordinate flats of abaxial surfaces of the GR and RE samples. The GR circle represents L^* = 56, a^* = −6, and b^* = 16; and the RE circle represents L^* = 77, a^* = 9, and b^* = 17. The circle represents the rounded number of average values from triplicates of each phenotypic sample. Error bars represent ± SE of biological triplicates. Asterisks represent significant differences in gene expression between GR and RE parts (one asterisk for P < 0.05 and two asterisks for P < 0.01)
