Effects of exogenous ALA on membrane peroxidation injury in partial GSTU43-silenced tomato leaves under low temperature. a malondialdehyde (MDA) levels, (b) relative electrical conductivity (REC), (c) maximal quantum yield of PSII photochemistry (Fv/Fm). 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, these indexes 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)
