Bud sports are infrequent changes in phenotype affecting shoots of woody perennials but the molecular basis of these mutations has rarely been identified. In this report, we show that the bronze-coloured berries of the Malian cultivar, a documented bud sport of the wine grape Cabernet Sauvignon (Vitis vinifera L.), lack anthocyanins in the subepidermal cells compared to the red/black berried Cabernet Sauvignon in which both the epidermis and several subepidermal cell layers contain anthocyanin… Expand
Color Intensity of the Red-Fleshed Berry Phenotype of Vitis vinifera Teinturier Grapes Varies Due to a 408 bp Duplication in the Promoter of VvmybA1
TLDR
Quantitative real time PCR and HPLC analysis of leaf and berry samples showed that the GCE repeat number strongly correlates with an increase of the expression of VvmybA1 itself and the VvUFGT gene regulated by it and the anthocyanin content. Expand
Molecular Characterization of a Bud Sport of Pinot gris Bearing White Berries
TLDR
The molecular characterization of a white color mutation in Pinot gris shows a triallelic profile at the locus based on genotyping with a microsatellite DNA marker, indicating that genetically different cell layers, L1 and L2, coexisted in the berries. Expand
Genetic analysis of a white-to-red berry skin color reversion and its transcriptomic and metabolic consequences in grapevine (Vitis vinifera cv. ‘Moscatel Galego’)
TLDR
It is proposed that the reduced activity of the flavonoid tri-hydroxylated sub-branch and decreased anthocyanin synthesis and modification and methylation and acylation are the potential causes for the mild red-skinned coloration in the pigmented revertant. Expand
Color recovery in berries of grape (Vitis vinifera L.) 'Benitaka', a bud sport of 'Italia', is caused by a novel allele at the VvmybA1 locus.
TLDR
It is found that the VvmybA1 locus of 'Benitaka' is heterozygous for the V vmybBA1a allele (non-functional) and a novel Vv mybA 1(BEN) allele, and that VvMybA2(B EN) restored VvMYbA3 transcripts. Expand
A novel bud sport from the ‘Benitaka’ table grape cultivar (Vitis vinifera L.) improves sugar and anthocyanin accumulation at the berry ripening stage
TLDR
The mutation in ‘early-ripening Benitaka’ affected sugar and anthocyanin metabolism, which might be related with accumulation of sugar and AnthOCyanin and other early-ripens phenotypes. Expand
Flower color mutation caused by spontaneous cell layer displacement in carnation (Dianthus caryophyllus).
TLDR
A cell layer rearrangement which is the cause of spontaneous flower color mutation by using two carnation cultivars that are presumably periclinal chimeras, 'Feminine Minami' (deep pink flower) and its recessive sport 'Tommy Minami" (pinkish red flower). Expand
Parentage of Merlot and related winegrape cultivars of southwestern France: discovery of the missing link
TLDR
The discovery of the key genetic role of a previously unknown cultivar in the origins of some significant cultivars reinforces the importance of deep exploration, before it is too late, to discover original genotypes which have not yet been collected or referenced. Expand
COMPARATIVE ANALYSIS OF THE VvMybA1 LOCUS ALLEAL STATE IN SOME INDIGENOUS AND INTRODUCENT GRAPEVINE VARIETIES
TLDR
Alleles of the VvMybA1 gene were first identified in native Russian grape varieties of Chardonnay, Sibirkovskii, Cabernet Cortis and Sypun cherny varieties and found that the alleles of colored varieties have a structure characteristic for varieties with a pronounced color of berries, while uncolored varieties apparently have a specific reason for the loss of color. Expand
A group of grapevine MYBA transcription factors located in chromosome 14 control anthocyanin synthesis in vegetative organs with different specificities compared with the berry color locus
TLDR
The involvement of additional anthocyanin regulators in grapevine is demonstrated and an evolutionary divergence between the two grape color loci for controlling additional targets of the flavonoid pathway is suggested. Expand
Transcriptomic analysis of Citrus clementina mandarin fruits maturation reveals a MADS-box transcription factor that might be involved in the regulation of earliness
TLDR
This work analyzes the evolution of the transcriptome during fruit ripening in 3 sport mutations derived from the Fina clementine (Citrus clementina) mandarin: Clemenules (CLE), Arrufatina (ARR) and Hernandina (HER) that differ in their harvesting periods to identify a transcription factor that could be involved in the early phenotype.

Association of VvmybA1 gene expression with anthocyanin production in grape (Vitis vinifera) skin-color mutants
By using white-skinned cultivars (‘Italia’ and ‘Muscat of Alexandria’) and putative red-skinned sports (‘Ruby Okuyama’ and ‘Flame Muscat’) from the white cultivars, we analyzed the expression andExpand
Anthocyanin composition and anthocyanin pathway gene expression in grapevine sports differing in berry skin colour
TLDR
The results suggest that control of 3‐monoglucoside synthesis and modification vary in the sports, and the lack of anthocyanins in white‐skinned varieties or sports correlates with a lack of expression of the UFGT gene, although the expression of some other flavonoid pathway genes was also decreased. Expand
Diversification within grapevine cultivars goes through chimeric states.
TLDR
The accumulation of somatic mutations and cell layer rearrangements allowed us to deduce the relationships between the various genotypes and to open a way for understanding the diversification process and the phylogeny in the 'Pinot' group. Expand
Genetic structure and differentiation in cultivated grape, Vitis vinifera L.
TLDR
The overall organization of genetic diversity suggests that the germplasm of cultivated grape represents a single complex gene pool and that its structure is determined by strong artificial selection and a vegetative mode of reproduction. Expand
Myb-related genes of the Kyoho grape (Vitis labruscana) regulate anthocyanin biosynthesis
TLDR
The results strongly suggest that MybA genes are involved in the regulation of anthocyanin biosynthesis in the grape via expression of the UFGT gene. Expand
Genetic and physical mapping of the grapevine powdery mildew resistance gene, Run1, using a bacterial artificial chromosome library
TLDR
A comparison of physical and genetic mapping data indicates that recombination is severely repressed in the vicinity of Run1, possibly due to divergent sequence contained within the introgressed fragment from M. rotundifolia that carries the Run1 gene. Expand
Chimerism in grapevines: implications for cultivar identity, ancestry and genetic improvement
TLDR
It appears that grapevine chimerism can not only modify phenotype but can also impact on grapevine improvement as both genetic transformation and conventional breeding strategies separate mutations in the L1 and L2 cell layers. Expand
Association of dwarfism and floral induction with a grape ‘green revolution’ mutation
TLDR
The conversion of tendrils to inflorescences in the mutant demonstrates that the grapevine tendril is a modified inflorescence inhibited from completing floral development by GAs, providing genetic evidence that GAs inhibit flowering in grapevine. Expand

TLDR
The study of flower color polymorphisms in the morning glory is reviewed as a model for the analysis of adaptation and it is found that almost all of the mutations that determine phenotypic differences are the result of transposon insertions. Expand
