“…On the other hand, the medium based of macronutrient from Nitsch medium showed the best results, which was used in this study. Similar results were obtained by Barticevic et al (2004) in a project that involved many more varieties and analysis in generated seedlings. , shows a sample of progeny from hybridization between Princesa and Perlette varieties, which showed low vigor and a thick stem.…”

“…A positive correlation has been described between the final berry weight and seed content [ 19 ] in segregating populations [ 20 – 24 ], possibly being the result of growth regulators produced by seeds [ 6 , 25 ]. Interestingly, in stenospermocarpic varieties pollination occurs normally although the embryo development process aborts early, approximately 2 to 4 weeks after fertilization, while berry development continues normally [ 5 , 24 ].…”

Transcriptome profiling of grapevine seedless segregants during berry development reveals candidate genes associated with berry weight

BackgroundBerry size is considered as one of the main selection criteria in table grape breeding programs. However, this is a quantitative and polygenic trait, and its genetic determination is still poorly understood. Considering its economic importance, it is relevant to determine its genetic architecture and elucidate the mechanisms involved in its expression. To approach this issue, an RNA-Seq experiment based on Illumina platform was performed (14 libraries), including seedless segregants with contrasting phenotypes for berry weight at fruit setting (FST) and 6–8 mm berries (B68) phenological stages.ResultsA group of 526 differentially expressed (DE) genes were identified, by comparing seedless segregants with contrasting phenotypes for berry weight: 101 genes from the FST stage and 463 from the B68 stage. Also, we integrated differential expression, principal components analysis (PCA), correlations and network co-expression analyses to characterize the transcriptome profiling observed in segregants with contrasting phenotypes for berry weight. After this, 68 DE genes were selected as candidate genes, and seven candidate genes were validated by real time-PCR, confirming their expression profiles.ConclusionsWe have carried out the first transcriptome analysis focused on table grape seedless segregants with contrasting phenotypes for berry weight. Our findings contributed to the understanding of the mechanisms involved in berry weight determination. Also, this comparative transcriptome profiling revealed candidate genes for berry weight which could be evaluated as selection tools in table grape breeding programs.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-016-0789-1) contains supplementary material, which is available to authorized users.

“…Notably though, the berry size of VT variety was considerably larger when compared to FS variety. This can be due to the previously described positive correlation between the grape berry weight and seeds in various grape cultivars [35–39], as it may be probably due to effects of growth regulators being produced by seeds [40,41].…”

Comparative phenotypic and transcriptomic analysis of Victoria and flame seedless grape cultivars during berry ripening

et al. 2020

Grape berry development is a highly coordinated and intricate process. Herein, we analyzed the phenotypic and transcriptomic patterns of Victoria (VT) and Flame Seedless (FS) grape varieties during berry development. Physiological analysis and transcriptomic sequencing were performed at four berry developmental phases. VT berry size was comparatively larger to the FS variety. At maturity, 80 days post-anthesis (DPA), the FS soluble solids were 61.8% higher than VT. Further, 4,889 and 2,802 differentially expressed genes were identified from VT and FS 40 DPA to 80 DPA development stages, respectively. VvSWEET15, VvHXK and MYB44 genes were up-regulated during the post-anthesis period, while bHLH14, linked to glucose metabolism, was gradually down-regulated during berry development. These genes may have significant roles in berry development, ripening and sugar accumulation.
