Fig. 10From: 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 temperatureEffect of application of exogenous GABA at low temperature on (a) DAPs and (b) RT-qPCR analysis of genes related to oxidative pentose phosphate pathway and purine metabolism. 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: ALDH1: Aldehyde dehydrogenase; CYFBP: Fructose-1,6-bisphosphatase; FBA3: fructose-1, 6-bisphosphate aldolaseBack to article page
