Fig. 4From: H2O2 mediates ALA-induced glutathione and ascorbate accumulation in the perception and resistance to oxidative stress in Solanum lycopersicum at low temperaturesALA regulated the redox status of glutathione and ascorbate to inhibit low temperature-induced oxidative stress. a Content of GSH + GSSG, GSH, and GSSG, and the ratio of GSH/GSSG; b Content of AsA + DHA, AsA, and DHA, and the ratio of AsA/DHA. Data are expressed as the mean ± standard error of three independent biological replicates. Different letters above the bars indicate a significant difference at P < 0.05Back to article page
