Figure 2.

The relative expression level of genes encoding ABA co-receptors (PYL1, PYL2 and RCAR1, RCAR3) in axes of apple embryos isolated after 24 h of seeds imbibition in water (C₀), in axes of embryos imbibed in water for 3 h after seed coat removal (C), in axes of embryos fumigated with NO for 3 h (NO). The expression of genes was normalized to UBI as a reference gene. Two technical replicates were performed for each four biological replicates. Error bars represent ±SD; a, b homogenous groups.
