Fig. 5From: Comparative analysis of two phytochrome mutants of tomato (Micro-Tom cv.) reveals specific physiological, biochemical, and molecular responses under chilling stressEffect of chilling stress on a malondialdehyde (MDA) content and b–f activities of antioxidant enzymes in leaves of the wild-type genotype (MT) and aurea (aur) and high pigment1 (hp1) mutants of tomato cv. Micro-Tom under control and chilling stress conditions. Symbols that are not similar show significant differences (calculated by Tukey’s test, P < 0.05). Comparisons between control and stress within the same genotype were denoted in upper case letters, while comparisons among genotypes under the same treatment (control or stress) were denoted in lower case lettersBack to article page
