Effect of heat stress on the activity and transcript levels of superoxide dismutase (SOD) enzyme in stems and roots of different squashes. (a) SOD activity in stems and roots; (b) Relative abundance of antioxidant gene transcripts determined through qRT-PCR in “C. moschata”, “C. maxima” and “Maxchata” stems and roots at 30, 37, and 42 °C using ACTIN as the internal control. The values are the means ± SD (n = 3). The different letters indicate significant differences between various temperature treatments (p < 0.05); and (c) The DNA bands were obtained using Cu/ZnSOD, FeSOD, MnSOD and ACTIN specific primers through gel electrophoresis after reverse transcriptase-PCR.
