Relative level of transcription of pluripotency genes in calli from leaves of the tae mutant cultivated on callusogenesis medium and regeneration medium as compared to WT. The level of gene expression in WT calli was taken as one unit. Values are presented as arithmetic mean ± standard error of the mean of three biological replicates. The asterisk marks statistically significant differences from the level of WT expression (Student’s t-test, significance level: * 0.01 < P < 0.05; ** 0.001 < P < 0.01; *** P < 0.001). Light gray and dark color indicate data for calli on callusogenesis and regeneration media, respectively.
