Fig. 8From: Genome-wide identification analysis of the 4-Coumarate: CoA ligase (4CL) gene family expression profiles in Juglans regia and its wild relatives J. Mandshurica resistance and salt stressCharacteristics of two Juglans species leaves under salt stress. (A) Phenotypes of J. regia and J. mandshurica leaves under salt stress, where ddH2O2 indicated control group, 150 mmol/L Na2SO4 indicated salt-treated group; (B) Antioxidant enzyme activities of J. regia and J. mandshurica leaves under salt stress. CAT: Catalase, POD: Peroxidase, SOD: Superoxide dismutase. The red and blue columns indicated the control and salt-treated groups, respectively. The statistical significance using t-test. *=p < 0.05, **=p < 0.01, ***=p < 0.001Back to article page
