From: Physiological and iTRAQ-based proteomic analyses reveal the function of exogenous γ-aminobutyric acid (GABA) in improving tea plant (Camellia sinensis L.) tolerance at cold temperature

Effect of application of exogenous GABA at low temperature on (a) DAPs and (b) RT-qPCR analysis of genes related to TCA cycle, glyoxylate cycle and carbon fixation in photosynthetic organisms. Transcript abundance was calculated according to the difference in cycle threshold values between the target gene and β-actin transcripts normalized by the 2−ΔΔCT method. The mRNA levels of the genes in tea leaves at 0 h were set as 1.0. Data represent the mean value ± standard deviation. Means with different letters significantly differ from each other (p ≤ 0.05). Abbreviations: AGT1: alanine-glyoxylate transaminase; FBA2: fructose-bisphosphate aldolase 2; GAPB: glyceraldehyde-3-phosphate dehydrogenase B subunit; GDH3: glutamate dehydrogenase 3; GGAT2: glutamate--glyoxylate aminotransferase 2-like; GLDP2: glycine decarboxylase P-protein 2; GLO1: glyoxalase; NADP-ME4: NADP-malic enzyme 4; PDH-E1: pyruvate dehydrogenase E1; PMDH1: peroxisomal NAD-malate dehydrogenase 1; RBCL: ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit; RBCS-2B: Ribulose bisphosphate carboxylase small chain 2B; SDH1–1: succinate dehydrogenase 1–1
