Figure 7. Expression of (A) SUVH2 (B) SUVH5 (C) SUVH6 (D) SUVH8 in F1 progeny of wild type (15D8) and mutant (dcl2 and dcl3) plants exposed to heat and control plants. Y-axis shows arbitrary units of gene expression, standardized to tubulin. “C₁” – the progeny of plants grown at normal conditions in F0. “S₁” – the progeny of plants exposed to heat in F0. “+” and “-” indicate exposure to stress or growth in uninduced conditions, respectively. Bars show standard error of the mean (SEM) calculated from 3 technical repeats. Asterisks (*) indicate a significant difference between control (-) and stress (+) with the same parental treatment, between different treatments (C₁ vs S₁) or between different mutants, as calculated using a t test (P ≤ 0.05).
