Diagram of FaSnRK2.6 signaling in relation to the regulation of strawberry fruit development and ripening. Levels of FaSnRK2.6 transcript decrease during the progression of strawberry fruit development and ripening are shown. OE- and RNAi-mediated suppression of FaSnRK2.6 expression delay and accelerate, respectively, the onset of strawberry fruit ripening. ABA and high temperature down-regulate the expression of FaSnRK2.6, thereby promoting strawberry fruit ripening. As seed maturation and dispersal can be regarded as a strategy for plants to withstand environmental stresses, the regulation of strawberry fruit ripening by FaSnRK2.6 embodies a role of FaSnRK2.6 in stress signaling.
