In spite of the abundance archaeological, bio-archaeological, historical and genetic data, origins, biogeography, identity ancient grapevine cultivars mechanisms domestication are still largely unknown. Here, analysis variation in seed morphology aims to provide accurate criteria for discrimination between wild grapes modern understand changes functional traits relation process. This approach is also used quantify phenotypic diversity cultivated compartments a starting point comparing...
Agrobiodiversity—the variation within agricultural plants, animals, and practices—is often suggested as a way to mitigate the negative impacts of climate change on crops [S. A. Wood et al. , Trends Ecol. Evol. 30, 531–539 (2015)]. Recently, increasing research attention has focused exploiting intraspecific genetic crop [Hajjar Agric. Ecosyst. Environ. 123, 261–270 (2008)], despite few relevant tests how this diversity modifies forecasts. Here, we quantify diversity, via cultivars, changes...
We elucidate grapevine evolution and domestication histories with 3525 cultivated wild accessions worldwide. In the Pleistocene, harsh climate drove separation of grape ecotypes caused by continuous habitat fragmentation. Then, occurred concurrently about 11,000 years ago in Western Asia Caucasus to yield table wine grapevines. The domesticates dispersed into Europe early farmers, introgressed ancient western ecotypes, subsequently diversified along human migration trails muscat unique...
Grapevine (Vitis vinifera subsp. vinifera) is one of the most important and ancient horticultural plants in world. Domesticated about 8–10,000 years ago Eurasian region, grapevine evolved from its wild relative (V. sylvestris) into very diverse heterozygous cultivated forms. In this work we study genetic structure a large sample varieties, to interpret wide diversity at morphological molecular levels link it cultivars utilization, putative geographic origin historical events. We analyzed...
Grapevine is a very important crop species that mainly cultivated worldwide for fruits, wine and juice. Identification of the genetic bases performance traits through association mapping studies requires precise knowledge available diversity how this structured varies across whole genome. An 18k SNP genotyping array was evaluated on panel Vitis vinifera cultivars we obtained data set with no missing values total 10207 SNPs 783 different genotypes. The average inter-SNP spacing ~47 kbp, mean...
Grapevine (Vitis vinifera), one of the most important fruit species in Classical Mediterranean world, is thought to have been domesticated first South-Western Asia, during Neolithic. However, domestication process remains largely unknown. Crucial unanswered questions concern duration (rapid or slow?) and related geographical area (single multiple-origins?). Seeds from grapevine its wild ancestor are reported differ according shape. Our work aims, first, confirm this difference secondly...
In Vitis vinifera L., domestication induced a dramatic change in flower morphology: the wild sylvestris subspecies is dioecious while hermaphroditism largely predominant domesticated subsp. V. v. vinifera. The characterisation of polymorphisms genes underlying sex-determining chromosomal region may help clarify history grapevine and evolution sex chromosomes plants. genus Vitis, determination putatively controlled by one major locus with three alleles, male M, hermaphrodite H female F, an...
Seedlessness is greatly prized by consumers of fresh grapes. While stenospermocarpic seed abortion determined the SEED DEVELOPMENT INHIBITOR (SDI) locus usual source seedlessness in commercial grapevine (Vitis vinifera) cultivars, underlying sdi mutation remains unknown. Here, we undertook an integrative approach to identify causal mutation. Quantitative genetics and fine-mapping two 'Crimson Seedless'-derived F1 mapping populations confirmed major effect SDI delimited a 323-kb region on...
As for many crops, new high-quality grapevine varieties requiring less pesticide and adapted to climate change are needed. In perennial species, breeding is a long process which can be speeded up by gaining knowledge about quantitative trait loci linked agronomic traits variation. However, due the juvenile period of these establishing numerous highly recombinant populations high resolution mapping both costly time-consuming. Genome wide association studies in germplasm panels an alternative...
The first high quality draft of the grape genome sequence has just been published. This is a critical step in accessing all genes this species and increases chances exploiting natural genetic diversity through association genetics. However, our basic knowledge extent allelic variation within still not sufficient. Towards goal, we constructed nested core collections (G-cores) to capture simple repeat (SSR) cultivated compartment (Vitis vinifera L. subsp. sativa) from world's largest germplasm...
A parentage and a paternity-based approach were tested for estimation of pollen-mediated gene flow in wild grapevine (Vitis vinifera L. subsp. silvestris), wind-pollinated species occurring Mediterranean Europe southwestern Asia. For this purpose, 305 seedlings collected 2 years at locations France from 4 female individuals 417 prospected Italy analyzed using 20 highly polymorphic microsatellite loci. Their profiles compared with database consisting 3203 accessions the Institut National de...
Aim: Phenology is a key factor in explaining the distribution and diversity of current vineyards France. This work has objective to summarize different studies developed France analyze grapevine phenology.Methods results: Several topics are presented: general description all historical databases observatory networks during last 70 years; an overview models calculate main phenological stages; analysis results obtained using these context climate change impacts on viticulture France; finally...
Aim Vitis subg. provides an example of a plant disjunction occurring in the Northern Hemisphere. It shows broad morphological variation but is assumed to be species complex with limited genetic differentiation. Based on comprehensive sampling taxa and polymorphism both chloroplast nuclear DNA, we assessed within this subgenus. Our aims were clarify relationships among examine their historical biogeography. Location Asia, Europe, North America. Methods We analysed total 30 putative hybrids...
Abstract Background Cultivated grapevines, Vitis vinifera subsp. sativa , evolved from their wild relative, V. sylvestris . They were domesticated in Central Asia the absence of powdery mildew fungus, Erysiphe necator which is thought to have originated North America. However, resistance has previously been discovered two Asian cultivars and Chinese species. Results A set 380 unique genotypes evaluated with data generated 34 simple sequence repeat (SSR) markers. The included 306 cultivars,...
