From: Abscisic acid synergizes with sucrose to enhance grain yield and quality of rice by improving the source-sink relationship

Fig. 7

Effect of sucrose and abscisic acid (ABA) alone or in combination on the sucrose transport and metabolism of rice plants. a and b Effect of sucrose and ABA alone or in combination on the expression levels of sucrose transporters (SUTs), SUT1 and SUT2, respectively, in leaves, sheath-stems, and grains of rice at 15 days after flowering (DAF); cf, effect of sucrose and ABA alone or combination on the expression levels of invertase1 (INV1), cell-wall invertase2 (CIN2), sucrose synthase (SUS), SUS2 and SUS4 in grains of rice at 15 DAF. Vertical bars denote standard deviations (n = 3). Different letters indicate significant differences between chemical treatments (P < 0.05)
