Schematic glycolytic and citric acid pathways illustrating the proteins identified responsive to drought stress at RBP level (orange boxes) with the bold green GAPC2 only identified in the current study and others including the enzymes in grey boxes have been previously identified [12]. Enzymes in orange boxes namely pfkA, GAPC2, ALDH7B4, ACO and MDH1 significantly increase and PDHA decrease in abundance after drought stress treatment (Additional file 1: Table S1). The figure is adapted from [12]). Abbreviations in order of appearance: pgm: phosphoglucomutase 2; GPI: glucose-6-phosphate isomerase; FBP: fructose 1.6-bisphosphate phosphatase or high cyclic electron flow 1; pfkA: phosphofructokinase 3; ALDO1: fructose bisphosphate aldolase 1; P: phosphate; TPI: triosephosphate isomerase; GAPC2: glyceraldehyde-3-phosphate dehydrogenase C2; P₂: bisP; PGK: phosphoglycerate kinase; G3-P: glyceraldehyde 3-phosphate; ENO1: enolase; PK: pyruvate kinase; PDC2: pyruvate decarboxylase 2; PDHB: transketolase or pyruvate dehydrogenase E1 component beta subunit; PDHA: pyruvate dehydrogenase E1 component subunit alpha-3, chloroplastic; DLAT: mitochondrial pyruvate dehydrogenase subunit 2–2 or dihydrolipoyllysine-residue acetyltransferase component 2 of pyruvate dehydrogenase complex; ALDH7B4: aldehyde dehydrogenase 7B4; CS: citrate synthase; ACO: aconitase; IDH1: NADP-specific isocitrate dehydrogenase; DLST: dihydrolipoamide succinyltransferase; ACLY: ATP-citrate lyase; FUM1: fumarase 1; MDH1: cytosolic NAD-dependent malate dehydrogenase; MDH2: mitochondrial malate dehydrogenase 2
