Expression levels of OsSRT1 affect glycolytic activity. (A) Relative activities of glycolytic enzymes HXK, PFK, PK, and GAPDH in 12-d-old seedlings of OsSRT1 RNAi (R1, R2 and R3), and over-expression transgenic (OX1, OX2 and OX3) compared to their respective wild type (MH63 and ZH11). (B) NADH/NAD⁺ ratios in the different genotypes. (C) Glucose contents in the OsSRT1 transgenic plants relative to wild type. Bars are means ± SD from three biological replicates and each replicate with three technical repeats. Significant differences are indicated (t test, n = 3), *P < 0.05; **P < 0.01.
