Abstract
Effects of endogenous abscisic acid (ABA) and ABA signal transduction on anthocyanin and photoreceptors in grape berries (Vitis labruscana) were examined using NDGA, the inhibitor of the rate-limiting ABA biosynthesis enzyme in grapes, and PANMe, an ABA receptor interaction antagonist. Both NDGA and PANMe treatments decreased anthocyanin concentrations. The expressions of VvSnRK2.6, VvABF2, and VvPP2C9 in NDGA treatment were not significantly different from the untreated control; by contrast, PANMe treatment decreased the expressions of VvSnRK2.6, VvABF2, and VvPP2C9. Both NDGA and PANMe treatments decreased the expressions of VvPhot2 and VvCRYa. These results suggest that both endogenous ABA concentrations and ABA signaling affect anthocyanin synthesis and photoreceptor genes such as VvPhot2 and VvCRYa in grape skins.
期刊介绍:
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
