Evolution of the VvMybA gene family, the major determinant of berry colour in cultivated grapevine (Vitis vinifera L.)

Polymorphisms in the grape transcription factor family VvMybA are responsible for variation in anthocyanin content in the berries of cultivated grapevine (Vitis vinifera L. subsp. sativa). Previous study has shown that white grapes arose through the mutation of two adjacent genes: a retroelement insertion in VvMybA1 and a single-nucleotide polymorphism mutation in VvMybA2. The purpose of this study was to understand how these mutations emerged and affected genetic diversity at neighbouring sites and how they structured the genetic diversity of cultivated grapevines. We sequenced a total of 3225 bp of these genes in a core collection of genetic resources, and carried out empirical selection tests, phylogenetic-and coalescence-based demographic analyses. The insertion in the VvMybA1 promoter was shown to have occurred recently, after the mutation of VvMybA2, both mutations followed by a selective sweep. The mutational pattern for these colour genes is consistent with progressively relaxed selection from constrained ancestral coloured haplotypes to light coloured and finally white haplotypes. Dynamics of population size in the VvMybA genes showed an initial exponential growth, followed by population size stabilization. Most ancestral haplotypes are found in cultivars from western region, whereas recent haplotypes are essentially present in table cultivars from eastern regions where intense breeding practices may have replaced the original diversity. Finally, the emergence of the white allele was followed by a recent strong exponential growth, showing a very fast diffusion of the initial white allele.

“…The primary domestication syndromes in grape are hermaphroditism and the size of berries and bunches (Levadoux, 1956). Colour variation is neither considered as a primary target for selection nor correlated with a particular geographic origin (Sefc et al, 2000;Lijavetzky et al, 2006).…”

“…Because null alleles can sometimes lead to a misunderstanding of parent-offspring relationships, we conducted parentage analyses considering null alleles (Moriguchi et al 2004); the result, however, was the same as when null alleles were not considered (data not shown); therefore, we suggest that these clones are full-sibs of N14. In horticulture, pedigree relationships between cultivars are frequent (Bowers et al 1999, Sefc et al 2000, while pedigree relationships between cultivars have rarely been confirmed in forestry.…”

“…In clonal forestry, a specific genotype or a few superior genotypes tend to be used for plantations over large areas for long periods of time (Zobel and Talbert 1984), and thus the genetic diversity of commercial populations tends to be smaller than that of natural populations. Commercial genotypes (cultivars), which are often selected from relatively restricted areas, are produced by artificial or spontaneous crossings (Sefc et al 1998), and the genetic relationships between cultivars can sometimes be defined genetically, e.g., half-sib, full-sib, or parent-offspring relationships (Bowers et al 1999, Sefc et al 2000. For most forest trees, crossings between closely related genotypes result in severe inbreeding depression (Williams andSavolainen 1996, Kurinobu et al 1991), and thus information on the genetic diversity and genetic relationships among cultivars is essential for producing new cultivars via inter-cultivar crossings.…”

Genetic relationships and origin of commercial clones of Nangouhi, a vegetatively propagated cultivar of hinoki cypress (Chamaecyparis obtusa)

et al. 2008

Nangouhi, a vegetatively propagated cultivar of hinoki cypress (Chamaecyparis obtusa), includes several vegetatively propagated clones with commercial uses. The genetic diversity, relationships, and origin of Nangouhi were evaluated using ten highly polymorphic microsatellite markers and compared with those of natural hinoki populations. In terms of their genetics, Nangouhi clones appeared to be more closely related to each other than to natural populations. Parentage analysis indicated that clone N14, which is commonly found in the grounds of old shrines and temples, is a parent of 11 of the other clones, of which N6 and N13 had genotypes identical to N14 at eight and seven loci, respectively. These clones could have been produced by crossing N14 and genetically related individuals. Assignment tests were used to determine the genetic origin of Nangouhi clones using 25 natural hinoki populations as a reference. The possible sources of most of the clones were the Hikosan population in Kyushu and the Besshiyama population in Shikoku; however, several clones could not be assigned to any natural population. Crosses between Nangouhi and genetically unrelated plus tree clones and recurrent selection from the possible source populations are recommended for future breeding of Nangouhi.

Compendium of Transgenic Crop Plants

View full text Add to dashboard Cite

Grapevine ( Vitis vinifera ) is one of the major fruit crops in the world based on hectares cultivated and economic value, essentially due to the production of wine. The premium quality wines are produced from cultivars that enjoy a high level of consumer acceptance and are firmly entrenched in the market place. Transgenic breeding is attractive when compared to conventional breeding, because it offers a means of inserting new characters, such as disease resistance, into the genome of traditional cultivars without changing any of their other characteristics particularly wine typicity and quality. The aim of this review is to provide an outlook on the usefulness of genetic transformation in grapevine, not only to develop genetically modified cultivars for commercial release, but also as a valuable tool to understand the genetics and mechanisms of plant growth, development, and metabolism. Thus, the availability of improved and efficient techniques of transformation is needed to sustain the current development of grapevine genomics. Even if the future development of transgenic cultivars will depend essentially on a general acceptance of GM plant products by the consumers, it will require a complete and reliable assessment of their environmental and health safety, comparing the potential risks to the expected benefits of their use.
