“…Gibberellic acid (GA) and cytokinin (CK) are phytohormones used in seedless table grape production, and several studies have investigated their effects on berry development (Asano et al, 2001;Coombe, 1960;Hirano et al, 1996;Maoz et al, 2014;Mochida et al, 2013;Ohara et al, 2008;Okamoto et al, 2003;Peppi and Fidelibus, 2008;Ravest et al, 2017;Wang et al, 1993). Optimum methods for GA and CK application have been developed for different seedless grape cultivars (Asano et al, 2001;Fujishima et al, 2012;Fukunaga and Kurooka, 1988;Ishikawa and Baba, 2004;Ishikawa et al, 2003;Lu et al, 1997;Mochida et al, 2013;Thanarut et al, 2010;Zabadal and Bukovac, 2006). There are many reports on the effects of GA and CK on berry enlargement throughout the developmental stage (Acheampong et al, 2015;Hirano et al, 1996;Peppi and Fidelibus, 2008;Reynolds et al, 1992;Zabadal and Bukovac, 2006;Zoffoli et al, 2009).…”

Phytohormones play major roles in the berry maturation process. Gibberellic acid (GA) and cytokinin (CK) are phytohormones used in seedless table grape production. Several studies have been conducted on the effects of GA and CK application on berry development. However, the detailed mechanisms underlying their physiological effects on berry maturation after the veraison stage have not been clarified. Skin browning during maturation is a major commercial problem in yellow-green skinned grape cultivars including 'Shine Muscat', and expanding our knowledge of these mechanisms is a necessary step towards addressing this problem. In this study, we investigated the effects of GA and CK treatments from the veraison stage to the subsequent developmental stages of this grape berry. Both treatments resulted in enlarged berries and the suppression of increases in sugar content. Chlorophyll in the berry skin was less decomposed after GA/CK treatment, and the occurrence of skin browning in the maturation stage was reduced, as expression of the VvPP2Cs gene decreased. GA/CK treatment at the veraison stage (45-50 DAFB) reduced the expression levels of phytohormone-related genes, particularly those of VvGID1 and VvCHKs, which are involved in GA and CK signaling, respectively. These similar changes in gene expression patterns suggest phytohormonal crosstalk and a common expressional regulatory mechanism. VvACO2 and VvYUC1 expressions were significantly increased in skin browning samples, regardless of treatment, indicating involvement of the ethylene and auxin biosynthesis pathways in skin browning. Therefore, GA/CK treatment at the veraison stage may broadly affect phytohormone biosynthesis and signaling pathways in subsequent developmental stages, although the effect size greatly differs depending on the experimental conditions, including year and plant.

“…Nowadays, exogenous gibberellin (GA) is widely used to produce seedless berries through inducing parthenocarpy in many grape cultivars like 'Wink', 'Zuijinxiang', 'Fujiminori', 'Kyoho' and 'Early Sweet' [1][2][3][4][5][6]. Moreover, the ovules and seed stones are drastically inhibited during GA-induced grape I have checked and revised all.seedless berry development, whereas until now, this research mainly focused on the inhibited ovule development or seed embryo abortion induced by exogenous GA [4][5][6], but the aspect of GA-repressed seed-stone development is poorly reported. This has inspired us to study how GA mediates the inhibition of seed stones during seedless berry formation.…”

Exogenous GA is widely used to efficiently induce grape seedless berry development for significantly improving berry quality. Recently, we found that VvmiR166s are important regulators of response to GA in grapes, but its roles in GA-induced seedless grape berry development remain elusive. Here, the precise sequences of VvmiR166s and their targets VvREV, VvHB15 and VvHOX32 were determined in grape cv. ‘Rosario Bianco’, and the cleavage interactions of VvmiR166s-VvHB15/VvHOX32/VvREV modules and the variations in their cleavage roles were confirmed in grape berries. Exogenous GA treatment significantly induced a change in their expression correlations from positive to negative between VvmiR166s and their target genes at the seeds during the stone-hardening stages (32 DAF–46 DAF) in grape berries, indicating exogenous GA change action modes of VvmiR166s on their targets in this process, in which exogenous GA mainly enhanced the negative regulatory roles of VvmiR166s on VvHB15 among all three VvmiR166s-target pairs. The transient OE-VvmiR166a-h/OE-VvHB15 in tobacco confirmed that out of the VvmiR166 family, VvmiR166h/a/b might be the main factors in modulating lignin synthesis through inhibiting VvHB15, of which VvmiR166h-VvHB15-NtPAL4/NtCCR1/NtCCR2/NtCCoAMT5/NtCOMT1 and VvmiR166a/b-VvHB15-NtCAD1 are the potential key regulatory modules in lignin synthesis. Together with the GA-induced expression modes of VvmiR166s-VvHB15 and genes related to lignin synthesis in grape berries, we revealed that GA might repress lignin synthesis mainly by repressing VvCAD1/VvCCR2/VvPAL2/VvPAL3/Vv4CL/VvLac7 levels via mediating VvmiR166s-VvHB15 modules in GA-induced grape seedless berries. Our findings present a novel insight into the roles of VvmiR66s that are responsive to GA in repressing the lignin synthesis of grape seedless berries, with different lignin-synthesis-enzyme-dependent action pathways in diverse plants, which have important implications for the molecular breeding of high-quality seedless grape berries.
