Targeted Sequencing Suggests Wild-Crop Gene Flow Is Central to Different Genetic Consequences of Two Independent Pumpkin Domestications

چکیده

Studies of domestication genetics enrich our understanding how shapes genetic and morphological diversity. We characterized patterns variation in two independently domesticated pumpkins their wild progenitors to assess compare consequences domestication. To diversity pre- post-domestication identify genes targeted by selection during domestication, we analyzed ∼15,000 SNPs 48 unrelated accessions, including wild, landrace, improved lines for each pumpkin species, Cucurbita argyrosperma maxima . Genetic relative its progenitor was reduced only one subspecies, C. ssp. The species have different structure across status. Only 1.5% the features identified both were shared between species. These findings suggest that ancestral diversity, wild-crop gene flow, practices shaped similar crops ways, adding changes processes trait improvement impacts breeding potential modern crops.

Crop‐to‐wild gene flow and spatial genetic structure in the closest wild relatives of the cultivated apple

Crop-to-wild gene flow have important evolutionary and ecological consequences and require careful consideration in conservation programs for wild genetic resources of potential use in breeding programs and in assessments of the risk of transgene escape into natural ecosystems. Using 26 microsatellites and a set of 1181 trees, we investigated the extent of introgression from the cultivated appl...

Crop‐to‐wild gene flow and its fitness consequences for a wild fruit tree: Towards a comprehensive conservation strategy of the wild apple in Europe

Crop-to-wild gene flow can reduce the fitness and genetic integrity of wild species. Malus sylvestris, the European crab-apple fruit tree in particular, is threatened by the disappearance of its habitat and by gene flow from its domesticated relative, Malus domestica. With the aims of evaluating threats for M. sylvestris and of formulating recommendations for its conservation, we studied here, ...

Crop-to-wild gene flow, introgression and possible fitness effects of transgenes.

Crop-to-wild gene flow has received close attention over the past ten years in connection with the development and cultivation of transgenic crops. In this paper, we review key examples of crop/wild sympatry and overlapping flowering phenology, pollen and seed dispersal, the barriers to hybridisation and introgression, the evolution and fate of interspecific hybrids, their fitness, and the pote...

Genetic and ecological consequences of transgene flow to the wild flora.

Gene flow from crops to wild relatives by sexual reproduction is one of the major issues in risk assessment for the cultivation of genetically engineered (GE) plants. The main factors which influence hybridization and introgression, the two processes of gene flow, as well as the accompanying containment measures of the transgene, are reviewed. The comparison of risks between Switzerland and Eur...
