Effects of SnRK1.1 on the phosphorylation of glycolytic enzymes during submergence. (A) Schematic model of carbohydrate metabolism under submergence in Arabidopsis. Grey boxes indicate the gene under phosphorylation and white boxes represent the gene under transcriptional regulation. The arrows near the boxes show up- or down-regulation in Col-0 under submergence. Bold arrows indicate the promoting reaction under submergence. (B) The profile of soluble sugars, T6P, alanine, GABA, lactic acid, and α-KG in Col-0 and SnRK1.1 ^K48M under submergence. The data represent means ±SD from three independent biological replicates. Statistical differences between Col-0 and mutant samples were determined by Student’s t test. *, P <0.05.
