Effects of exogenous ALA on the glutathione and ascorbate content in partial GSTU43-silenced plants under low temperature. The VIGS plants leaves were treated with distilled water or 25 mg·L− 1 ALA, then exposed to normal condition (22 °C/20 °C, day/ night) or low temperature (15 °C/8 °C, day/ night) 12 h later. After 24 h of low temperature, the glutathione and ascorbate were measured. Data are expressed as the mean ± standard error of three independent biological replicates. The experiments were repeated for three times. Different letters above the bars indicate a significant difference determined by one-way ANOVA with Tukey’s test (P < 0.05). GSH, glutathione; GSSG, glutathione disulfide; AsA, ascorbate; DHA, dehydroascorbate
