From: Transcriptome profiling of low temperature-treated cassava apical shoots showed dynamic responses of tropical plant to cold stress

Figure 7

Detection of H 2 O 2 , transcript level and enzymatic activities of ROS scavenging genes in cassava subjected to cold (7°C) for 0, 4, 9, and 24 h. (A) DAB polymerization of in vitro and greenhouse-grown leaves subjected to cold. (B) Quantification of H2O2 content in the leaves from the greenhouse-grown plants. (C) The transcript levels of genes encoding for ROS scavenging enzymes in response to cold stress. (D, E) Enzyme activities of catalase and superoxide dismutase (SOD) in the leaves of greenhouse-grown plants. The single and double asterisks indicate a statistically significant difference at p < 0.05 and p < 0.01, respectively, for the data of the stress-treated samples compared to those of the unstressed samples. The mean values are calculated from three biological replicates; the error bars represent the standard error of the mean (SEM). Bar = 1 cm.
