From: SPL9 mediates freezing tolerance by directly regulating the expression of CBF2 in Arabidopsis thaliana

Fig. 4

SPL9 acts upstream of CBF2 on freezing tolerance. A The expression of CBF2 in Col-0 and rSPL9 plants by RT-qPCR. B Phenotype of the Col-0, cbf2, rSPL9 and rSPL9 cbf2 plants at normal and freezing stress conditions. C Survival rate of Col-0, cbf2, rSPL9 and rSPL9 cbf2 plants after freezing-treatment. Statistically distinct genotypes were identified by one-way ANOVA with post hoc LSD multiple comparison test. The pairwise comparison results are presented by inserting letters to describe statistics information: different letters indicate significant difference between genotypes at P < 0.05; the same letter indicates no significant difference between different genotypes. This experiment was biologically repeated for three times. D Ion leakage (%) of Col-0, cbf2, rSPL9 and rSPL9 cbf2 plants after freezing-treatment. Statistically distinct genotypes were identified by one-way ANOVA with post hoc LSD multiple comparison test. The pairwise comparison results are presented by inserting letters to describe statistics information: different letters indicate significant difference between genotypes at P < 0.05; the same letter indicates no significant difference between different genotypes.
