Expression profiles for starch-synthetic genes in endosperm in cultured panicles at 5 DAF of rice indica cultivar IR36 and japonica cultivar T65. a Effect of 0 and 100 mM sucrose on gene expression in each cultivar. Expression is given relative to the value at 0 mM sucrose. b Differences in gene expression between IR36 and T65 exposed to 0 or 100 mM sucrose. Significant differences were determined using biological triplicates and Student’s t-test (*P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001)
