nutrition | in the sweet almond genotype, the inner epidermis in the tegument facing the nucellus is rich in cytoplasmic and vacuolar prunasin beta-glucosidase activity, whereas in the bitter cultivar, the beta-glucosidase activity in this cell layer is low. In the bitter genotype, prunasin synthesized in the tegument is transported into the cotyledon via the transfer cells and converted into amygdalin in the developing almond seed, whereas in the sweet genotype, amygdalin formation is prevented because the prunasin is degraded upon passage of the beta-glucosidase rich cell layer in the inner epidermis of the tegument | Prunus dulcis |
