From: Exogenous GABA enhances muskmelon tolerance to salinity-alkalinity stress by regulating redox balance and chlorophyll biosynthesis

Fig. 8

Effects of exogenous GABA on the relative expression levels of chlorophyll biosynthesis enzyme genes at 48 h. a-f represent the genes expression of ALAD, PBGD, CHLM, POR, CHLG and CAO, respectively. H2O foliar prespraying for 8 h under normal nutrient solution cultivation conditions, (Control); 50 mM GABA foliar prespraying for 8 h under nutrient solution cultivation conditions, (CG); Normal nutrient solution containing 50 mM salinity-alkalinity and H2O foliar prespraying, (S); 50 mM GABA foliar prespraying for 8 h under salinity-alkalinity stress, (SG). The gene transcription levels in Control plants was normalized as 1. Data were analyzed with SPSS 20 software (IBM) using Tukey’s multiple range test at a significance level of P < 0.05, and different letters above the bars indicate a significant difference. Data were expressed as the mean ± standard error of three independent biological replicates
