“…The flavonoid biosynthesis pathway is under the control of Myb transcriptional factors, basic helix–loop-helix proteins (bHLH) and WD40-like proteins [7, 10, 17–19, 36, 38]. The first bHLH was submitted as VvMYCA1 (accession number EF193002; gene ID VIT_15s0046g02560) [76, 77], which was considered to regulate the expression of UFGT .…”

“…Generally, the flavonoid pathway of anthocyanins biosynthesis is under the control of Myb transcriptional factors, basic helix–loop-helix proteins(bHLH) and WD40-like proteins, which also play crucial roles in the regulation of flavonols and proanthocyanidins [10, 17–19, 36–38]. The research showed that the bHLH gene, VvMYC1 , was characterized as a component of the transcriptional complex regulating anthocyanins biosynthesis in grapevine [39].…”

BackgroundThe color of berry skin is an important economic trait for grape and is essentially determined by the components and content of anthocyanins. The fruit color of Chinese wild grapes is generally black, and the profile of anthocyanins in Chinese wild grapes is significantly different from that of Vitis vinifera. However, V. davidii is the only species that possesses white berry varieties among Chinese wild grape species. Thus, we performed a transcriptomic analysis to compare the difference of transcriptional level in black and white V. davidii, in order to find some key genes that are related to anthocyanins accumulation in V. davidii.ResultsThe results of anthocyanins detection revealed that 3,5-O-diglucoside anthocyanins is the predominant anthocyanins in V. davidii. It showed obvious differences from V. vinifera in the profile of the composition of anthocyanins. The transcriptome sequencing by Illumina mRNA-Seq technology generated an average of 57 million 100-base pair clean reads from each sample. Differential gene expression analysis revealed thousands of differential expression genes (DEGs) in the pairwise comparison of different fruit developmental stages between and within black and white V. davidii. After the analysis of functional category enrichment and differential expression patterns of DEGs, 46 genes were selected as the candidate genes. Some genes have been reported as being related to anthocyanins accumulation, and some genes were newly found in our study as probably being related to anthocyanins accumulation. We inferred that 3AT (VIT_03s0017g00870) played an important role in anthocyanin acylation, GST4 (VIT_04s0079g00690) and AM2 (VIT_16s0050g00910) played important roles in anthocyanins transport in V. davidii. The expression of some selected DEGs was further confirmed by quantitative real-time PCR (qRT-PCR).ConclusionsThe present study investigated the transcriptomic profiles of berry skin from black and white spine grapes at three fruit developmental stages by Illumina mRNA-Seq technology. It revealed the variety specificity of anthocyanins accumulation in V. davidi at the transcriptional level. The data reported here will provide a valuable resource for understanding anthocyanins accumulation in grapes, especially in V. davidii.Electronic supplementary materialThe online version of this article (doi:10.1186/s41065-016-0021-1) contains supplementary material, which is available to authorized users.

“…Berry color is the visual manifestation of organic compounds known as anthocyanins within the skin and occasionally flesh, as is the case with teinturier (French for “to dye” or “to stain”) grapes. Responsible for blue, red, and purple colors, five anthocyanins are found in Vitis species: malvidin, petunidin, peonidin, cyanidin, and delphinidin [ 2 ]. These compounds exist in mono- and diglucoside forms along with acylated and nonacylated forms, and the proportions of each type found in fruit can be used to differentiate species [ 3 ].…”

Evaluating and Mapping Grape Color Using Image-Based Phenotyping

Grape berry color is an economically important trait that is controlled by two major genes influencing anthocyanin synthesis in the skin. Color is often described qualitatively using six major categories; however, this is a subjective rating that often fails to describe variation within these six classes. To investigate minor genes influencing berry color, image analysis was used to quantify berry color using different color spaces. An image analysis pipeline was developed and utilized to quantify color in a segregating hybrid wine grape population across two years. Images were collected from grape clusters immediately after harvest and segmented by color to determine the red, green, and blue (RGB); hue, saturation, and intensity (HSI); and lightness, red-green, and blue-yellow values (L∗a∗b∗) of berries. QTL analysis identified known major QTL for color on chromosome 2 along with several previously unreported smaller-effect QTL on chromosomes 1, 5, 6, 7, 10, 15, 18, and 19. This study demonstrated the ability of an image analysis phenotyping system to characterize berry color and to more effectively capture variability within a population and identify genetic regions of interest.

“…The flavonoid pathway is regulated by a transcription complex composed of MYB, bHLH and WD40 (MBW) [5,6]. There is no doubt that anthocyanin biosynthesis is also regulated by the MBW transcription complex [7,8]. The glycosylation catalyzed by UDP-glucose:anthocyanidin:flavonoid glucosyltransferase (UFGT) is the key step of anthocyanin biosynthesis.…”

Background: Berry color is an important trait in grapes and is mainly determined by the anthocyanin content and composition. To further explore the coloring mechanism of grape berries, the F1 population of Vitis vinifera 'Red Globe' × 'Muscat Hamburg' was used to map the color locus, and transcriptome analysis was performed to assist in screening candidate genes. Results: A total of 438,407 high-quality single-nucleotide polymorphisms (SNPs) were obtained from wholegenome resequencing (WGS) of the population, and 27,454 SNPs were selected to construct a high-density genetic map. The selected SNPs were clustered into 19 linkage groups (LGs) spanning a genetic distance of 1442.638 cM. Berry color was evaluated by color grade, chromatic aberration, total anthocyanin content and anthocyanin composition. The Pearson correlation coefficients of these phenotypes in 2017 and 2018 were significant at the 0.01 level. The major color locus of MYBA1 and MYBA2 on LG2 was identified, explaining between 26 and 63.6% of all phenotypic variance. Furthermore, 9 additional QTLs with smaller effects were detected on Chr2, Chr4, Chr6, Chr11 and Chr17. Combined with the gene annotation and RNA-seq data, multiple new candidate genes were selected from the above QTLs. Conclusion: These results indicated that grape berry color is a quantitative trait controlled by a major color locus and multiple minor loci. Though the major color locus was consistent with previous studies, several minor QTLs and candidate genes associated with grape berry color and anthocyanin accumulation were identified in this study. And the specific regulatory mechanism still needs to be further explored.
