Expression patterns of CK biosynthetic genes (TaIPT2-2, TaLOG3 and TaLOG8) in the embryo (a,c,e) and endosperm (b,d,f) tissues of AC Domain and RL4452 during seed maturation. Log2 transformed array signal for each gene was expressed relative to that derived from AC Domain sample at 20 DAA, which was set to a value of 0. Asterisks indicate statistically significant differences in expression level between AC Domain and RL4452 samples (≥1-fold on log2-scale or ≥2-fold on symmetrical/linear-scale and P ≤ 0.05). Log2-scale and symmetrical/linear-scale fold changes in expression and the respective P values for the embryo and endosperm tissues are presented in Supplementary Tables S1 and S2. IPT, isopentenyltransferase; LOG, lonely guy.
