Fig. 2From: Comparative analysis of two phytochrome mutants of tomato (Micro-Tom cv.) reveals specific physiological, biochemical, and molecular responses under chilling stressEffects of chilling stress on stomatal aperture of tomato photomorphogenic mutants. The changes in stomatal aperture of tomato aur and hp1 mutants and the wild-type genotype (MT) were observed before and after chilling stress. The lower surfaces of the leaves with or without stress were examined under a microscopeBack to article page
