Spontaneous variation regarding grape berry skin color: A comprehensive study of berry development by means of biochemical and molecular markers

Genotyping studies are increasing the knowledge on grapevine biodiversity, particularly regarding grape berry skin color somatic variants, supporting the research on the color trait. This study aimed to evaluate the effect of the berry color locus, and its surrounding genomic region, on the color variation of the Portuguese white-skinned cultivars ‘Fernão Pires’ and ‘Verdelho’ and its derived red-berried somatic variants cv. ‘Fernão Pires Rosado’ and cv. ‘Verdelho Roxo’, respectively. The analysis of Gret1 insertion within the VvMYBA1 gene revealed no polymorphism responsible for white-to-red shift of the red-skinned cv. ‘Fernão Pires Rosado’ and cv. ‘Verdelho Roxo’. Moreover, VvMYBA2 showed an important role regarding the phenotypic variation of cv. ‘Fernão Pires’, through the recovery of the functional allele G on cv. ‘Fernão Pires Rosado’. Regarding the data obtained for cv. ‘Verdelho’ and cv. ‘Verdelho Roxo’, both cultivars showed Gret1 insertion on VvMYBA1 and non-functional T allele on VvMYBA2 in homozygosity for both cell layers of shoot apical meristem, suggesting the occurrence of other mutational events responsible for the color gain.

In Turkey, viticulture practices have displayed significant development with the production of high quality fresh grapes, juice, molasses and raisin. Grape berries contain high amount of phenolic compounds collected enormous interest due to their essential function in the improvement of produces attained from grapes, but also for their potential useful health effects as functional food. The purpose of present investigation was to reveal the effects of different colored shade nets on berry skin color and functional properties of grape juice. Four years old vines of â€˜Alphonse LavallÃ©eâ€™ table grape were cultivated soilless in about 70 L black plastic pots containing sterile peat and perlite mixture under controlled glasshouse condition. The grapevines were covered with different colored shading nets (yellow, blue, white, red, green and black) at the beginning of the summer period. At commercial maturity, investigations show that berry skin color and the analyzed biochemical features of â€˜Alphonse LavallÃ©eâ€™ table grape cultivar displayed great variations in response to the different colored shade net. Such differential effects should be evaluated when the use of shade nets is considered in protected viticulture to cope with environmental constraints. The findings may also be useful for the future experiments under conventional vineyard conditions.

Aims: The aim of this paper was to use recent transcriptomic tools available for grape in order to understand berry softening.Methods and results: A microarray bearing specific 50 mer oligonucleotide for 3,200 genes was used to study gene expression along 8 stages of berry development in Chardonnay and Shiraz berries. Transcripts corresponding to aquaporin genes and to genes involved in cell wall metabolism were studied in detail and ranked according to their pattern of expression.Conclusion: Several structural and regulatory genes whose expression pattern correlated with the late phases of ripening were identified. Significance and impact of study: This study provides a preliminary molecular basis to identify molecular markers of berry ripening.

Comprehensive Study

The evaluation of the variety suitability regarding each appellation’s specificities should be a strategy for maximizing the varieties’ oenological potential while contributing to the sustainable production of quality wines, keeping their typicity and rationalizing winemaking costs. Thus, the combination of several grape physicochemical attributes, modulated by climate and vineyard characteristics, providing knowledge for each grape variety’s oenological potential, is a relevant and reliable support for winemakers’ decisions. To prove this hypothesis, six mature grape varieties from three harvests, each one from three vineyard parcels with different topographical conditions from Bairrada Appellation (Portugal), were studied using analysis of variance–simultaneous components analysis (ASCA). The effects of harvest year and parcel on grape berry weight, pH, titratable acidity, total sugars, total phenolics, antiradical activity, and volatile composition in free and glycosidically-linked forms were analyzed. The compositional plasticity of autochthonous varieties (white Arinto and Bical and red Baga, Castelão, and Touriga Nacional) was observed. Sauvignon Blanc grape composition was significantly modulated by harvest. This study represents an important contribution for the maintenance of varieties’ biodiversity while contributing to establishing their peculiarities. Autochthonous varieties, if accurately exploited, can provide higher characteristic diversity than worldwide used varieties, an aspect to be more objectively taken into consideration by winemakers.

Root Restriction

Phytohormones strongly influence growth, development and nutritional quality of agricultural products by modulating molecular and biochemical changes. The purpose of the present study was to investigate the influence of root restriction (RR) treatment on the dynamic changes of main phytohormones during the berry development and ripening of “Summer Black” early ripening seedless grape (Vitis vinifera × V. labrusca), and to analyze the changes in the biosynthesis and signal transduction pathways of phytohormones by transcriptomics. Enzyme-linked immunosorbent assay (ELISA) and Ultra Performance Liquid Chromatography-High Resolution Mass Spectrometry (UPLC-HRMS) were used to quantify the phytohormone levels, and RNA-Seq was used to analyze the transcript abundance. The results showed that 23 transcripts involved in the phytohormone biosynthesis and 34 transcripts involved in the signal transduction pathways were significantly changed by RR treatment. RR also increased abscisic acid, brassinosteroid, ethylene, jasmonic acid and salicylic acid levels, while decreasing auxin, cytokinin, and gibberellin contents. The results of the present study suggest that RR treatment can accelerate the grape ripening process, and specific candidate genes were identified for further functional analysis.
