“…Interestingly, we have previously demonstrated that the exogenous pre-bloom application of GA 3 inhibited berry growth in seeded ‘Kyoho’ and ‘Red Globe’ cultivars, yet stimulated berry growth in ‘Thompson Seedless’ [17]. Similarly, it has also been shown that berry growth was inhibited in the seeded grape cultivar ‘Emperador’ and promoted in the seedless cultivar ‘Emperatriz’ upon GA 3 application [22]. Therefore, we supposed that whether the exogenous pre-bloom application of GA 3 to grape inflorescences stimulates berry production may be cultivar-dependent.…”

“…The exogenous pre-bloom application of gibberellic acid (GA 3 ) to grapevine, which is an economically important crop that has long been an important component of the human diet, is commonly used to induce seedlessness [17,18], establish early ripening [19], and enhance berry size in seedless cultivars [20-22]. However, despite its importance in viticulture, the precise mechanism by which GA elicits these complex outcomes remains elusive.…”

Gibberellin-induced changes in the transcriptome of grapevine (Vitis labrusca × V. vinifera) cv. Kyoho flowers

BackgroundGibberellins are well known for their growth control function in flower, fruit and seed development, and as such, exogenous gibberellic acid (GA) application plays an important role in viticulture. Unfortunately, the mechanism by which GA3 acts in the regulation of these complicated developmental processes in grape remains unclear.ResultsIn the present study, we demonstrated that application of GA3 to ‘Kyoho’ grapevine inflorescences at pre-bloom promoted flower opening, and induced fruit coloring as well as seed abortion. In an attempt to obtain a deeper understanding of the molecular mechanisms driving these responses to GA3 treatment, we performed large-scale transcriptome sequencing of grape flowers following GA3 treatment using Illumina sequencing technology. Global expression profiles of GA3-treated and untreated grape flowers were compared and a large number of GA3-responsive genes were identified. Gene ontology (GO) term classification and biochemical pathway analyses indicated that GA3 treatment caused changes in the levels of transcripts involved in cellular processes, reproduction, hormone and secondary metabolism, as well as the scavenging and detoxification of reactive oxygen species (ROS). These findings suggest that GA3-induced morphological alterations may be related to the control of hormone biosynthesis and signaling, regulation of transcription factors, alteration of secondary metabolites, and the stability of redox homeostasis.ConclusionsTaken together, this comprehensive inflorescence transcriptome data set provides novel insight into the response of grape flowers to GA3 treatment, and also provides possible candidate genes or markers that could be used to guide future efforts in this field.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-015-1324-8) contains supplementary material, which is available to authorized users.

“…Unlike seeded grapevine ( Vitis vinifera L.) cultivars, which have considerably high endogenous GA levels (Lavee, 1960; Kato et al, 1998; Agüero et al, 2000; Perez et al, 2000), berries of the usually small, stenospermocarpic varieties contain low GA quantities since they carry only seed traces, as a result of endosperm abortion following fertilization which leads to cessation of seed development (Iwahori et al, 1967; Cheng et al, 2013). GA application is therefore routinely used to stimulate stenospermocarpic berry development to a commercially acceptable size, and also for rachis stretching and cluster thinning (Weaver, 1958, 1965; Harrell and Williams, 1987).…”

“…GA application is therefore routinely used to stimulate stenospermocarpic berry development to a commercially acceptable size, and also for rachis stretching and cluster thinning (Weaver, 1958, 1965; Harrell and Williams, 1987). Issues of differential varietal responsiveness to such GA application have been reported in berries and other vegetative tissues/organs, including rachis and shoot (Weaver, 1958; Hagiwara et al, 1980; Mullins et al, 1992; Agüero et al, 2000). For example, while ‘Thompson seedless’ (TS) berries, required 3–4 applications of 30–45 μM of GA for a twofold increase in size (Dreier et al, 1998), application of 290 μM of GA 3 increased ‘Emperatriz’ berry size by only 20% (Agüero et al, 2000).…”

Abnormal Endogenous Repression of GA Signaling in a Seedless Table Grape Cultivar with High Berry Growth Response to GA Application

et al. 2017

Gibberellin (GA) application is routinely used in the table grape industry to increase berry size and cluster length. Although grapevine cultivars show a wide range of growth responsiveness to GA3 application, the reasons for these differences is unclear. To shed light on this issue, two commercial grapevine cultivars with contrasting berry response to GA were selected for comparative analysis, in which we tested if the differences in response: (1) is organ-specific or cultivar-related; (2) will be reflected in qualitative/quantitative differences in transcripts/proteins of central components of GA metabolism and signaling and levels of GA metabolites. Our results showed that in addition to the high response of its berries to GA, internodes and rachis of cv. Black finger (BF) presented a greater growth response compared to that of cv. Spring blush (SB). In agreement, the results exposed significant quantitative differences in GA signaling components in several organs of both cultivars. Exceptionally higher level of all three functional VvDELLA proteins was recorded in young BF organs, accompanied by elevated VvGID1 expression and lower VvSLY1b transcripts. Absence of seed traces, low endogenous GA quantities and lower expression of VvGA20ox4 and VvGA3ox3 were also recorded in berries of BF. Our results raise the hypothesis that, in young organs of BF, low expression of VvSLY1b may be responsible for the massive accumulation of VvDELLA proteins, which then leads to elevated VvGID1 levels. This integrated analysis suggests causal relationship between endogenous mechanisms leading to anomalous GA signaling repression in BF, manifested by high quantities of VvDELLA proteins, and greater growth response to GA application.
