Fig. 3From: Comparative physiological and coexpression network analyses reveal the potential drought tolerance mechanism of peanutPhotosynthetic characteristics in DS and DT under drought stress. The letters A-D represent Pn, Gs, Ci and Ls, respectively. Different letters indicate significant differences at the p < 0.05 level between different points for each genotype, * (p < 0.05) and ** (p < 0.01) indicate significant differences between two genotypes at the same treatment pointBack to article page
