This study identified and analyzed ABA signaling pathway genes in grapes, revealing the crucial roles of different gene families in plant growth, development, and stress tolerance. Exogenous ABA treatment can shorten the maturation period of grapes, while specific genes play important roles in tolerance to cold, heat, and drought stresses.
Abscisic acid (ABA) plays important roles in plant development and tolerance to abiotic stresses. Limited information is available regarding ABA signaling pathway genes in grape. In this study, 9 VvPYR/PYLs, 85 VvPP2Cs, 7 VvABIs, 7 VvSnRK2s, and 8 VvABFs were identified in the grape genome. Duplication analysis indicated that whole genome duplication might contribute to the expansion of these gene families. The comprehensive transcriptome analysis in various organs/tissues implied that most of these genes were tissue-specific, and few were environment-specific genes. Exogenous ABA treatment reduced the grape maturation period. VvPP2C59, VvPP2C60, VvPP2C66, and VvABF8 were all involved in tolerance to cold, heat, and drought stresses, revealing their crucial roles in regulating environmental stress responses. This work provides detailed information of ABA signaling pathway genes and new insights regarding their expression patterns during grape development and abiotic stress treatment.
