Effect of sucrose and abscisic acid (ABA) alone or in combination on trehalose metabolism in grains of rice. a Trehalose content under the sucrose, ABA, and ABA plus sucrose treatments; b–d, expression levels of trehalose-6-phosphate synthase1 (TPS1), trehalose-6-phosphate phosphatase7 (TPP7), and sucrose non-fermenting related protein kinase 1A (SnRK1A), respectively, under the sucrose, ABA, and ABA plus sucrose treatments. Vertical bars denote standard deviations (n = 3). Different letters indicate significant differences between chemical treatments (P < 0.05)
