Domestication is a good model for the study of evolutionary processes because of the recent evolution of crop species (<12,000 years ago), the key role of selection in their origins, and good archaeological and historical data on their spread and diversification. Recent studies, such as quantitative trait locus mapping, genome-wide association studies and whole-genome resequencing studies, have identified genes that are associated with the initial domestication and subsequent diversification of… Expand
Evolutionary Insights into the Nature of Plant Domestication
TLDR
Four new insights into plant domestication are discussed - that in general domestication is a protracted process, that unconscious (natural) selection plays a prominent role, that interspecific hybridization may be an important mechanism for crop species diversification and range expansion, and that similar genes across multiple species underlies parallel/convergent phenotypic evolution between domesticated taxa.

Soybean domestication: the origin, genetic architecture and molecular bases.
TLDR
Novel genomic information enables the search for polymorphisms that underlie variation in agronomic traits and highlights genes that exhibit a signature of selection, leading to the identification of a number of candidate genes that may have played important roles in soybean domestication, diversification and improvement. Expand
Parallel vs. Convergent Evolution in Domestication and Diversification of Crops in the Americas
TLDR
Crops domesticated in the Americas span a spectrum of genetic relatedness, have been domesticated for diverse purposes, and have responded to human selection by changes in many different traits, so provide examples of both parallel and convergent evolution at various levels. Expand

TLDR
More detailed information has become available on the organization of genetic diversity at the genome level and the effects of gene flow on diversity in different regions of the genome. Expand
The Impact of Genetic Changes during Crop Domestication
TLDR
The outcomes of crop domestication were shaped by selection driven by human preferences, cultivation practices, and agricultural environments, as well as other population genetic processes flowing from the ensuing reduction in effective population size. Expand
Evolutionary insights into plant breeding.
TLDR
This work highlights recent advances related to the role of selective sweeps and demographic history in shaping genetic architecture, how these breakthroughs can inform selection strategies, and the application of precision gene editing to leverage these connections. Expand
A domestication history of dynamic adaptation and genomic deterioration in sorghum
TLDR
A temporal series of archaeogenomes of the crop sorghum from a single locality in Egyptian Nubia shows a steady decline in genetic diversity over time coupled with an accumulating mutation load, revealing a model of domestication in which genomic adaptation and deterioration was not focused on the initial stages of domesticated but occurred throughout the history of cultivation. Expand
Parallelism and convergence in post-domestication adaptation in cereal grasses
TLDR
Current knowledge regarding trait convergence in the cereal grasses is reviewed and whether the complexity and dynamism of cereal genomes helped these species overcome potential limitations owing to domestication and achieve broad subsequent adaptation, in many cases through parallel means is considered. Expand
A domestication history of dynamic adaptation and genomic deterioration in Sorghum
TLDR
A temporal series of archaeogenomes of the crop sorghum from a single locality in Egyptian Nubia indicate no evidence for the effects of a domestication bottleneck, but instead reveal a steady decline in genetic diversity over time coupled with an accumulating mutation load. Expand

Comparative population genomics of maize domestication and improvement
TLDR
A comprehensive assessment of the evolution of modern maize based on the genome-wide resequencing of 75 wild, landrace and improved maize lines finds evidence of recovery of diversity after domestication, likely introgression from wild relatives, and evidence for stronger selection during domestication than improvement.

A bountiful harvest: genomic insights into crop domestication phenotypes.
TLDR
A diversity of underlying causative mutations affecting phenotypes important in plant domestication and crop improvement, including coding sequence substitutions, presence/absence and copy number variation, transposon activation leading to novel gene structures and expression patterns, diversification following gene duplication, and polyploidy leading to altered combinatorial capabilities are revealed.

ARCHAEOLOGICAL DATA REVEAL SLOW RATES OF EVOLUTION DURING PLANT DOMESTICATION
TLDR
This study indicates that the magnitudes of the rates of evolution during the domestication process, including the strength of selection, may be similar to those measured for wild species, and suggests that domestication may be driven by unconscious selection pressures similar to that observed for natural selection. Expand
The Effects of Artificial Selection on the Maize Genome
TLDR
Analysis of single-nucleotide polymorphisms in 774 genes indicates that 2 to 4% of these genes experienced artificial selection, and candidate selected genes with putative function in plant growth are clustered near quantitative trait loci that contribute to phenotypic differences between maize and teosinte.

SEED DISPERSAL AND CROP DOMESTICATION: SHATTERING, GERMINATION AND SEASONALITY IN EVOLUTION UNDER CULTIVATION
TLDR
The evidence indicates that the timescale of this evolution was considerably longer than previously supposed, raising questions about the mode of human mediated selection pressure and increasing the importance of the role of pre-domestication cultivation. Expand
The nature of selection during plant domestication
TLDR
It is demonstrated that a synthesis from the twin vantage points of genetics and archaeology can expand the understanding of the nature of evolutionary selection that accompanies domestication. Expand
Plant domestication, a unique opportunity to identify the genetic basis of adaptation
TLDR
It is concluded that bottom-up approaches to understanding domestication as an adaptive process hold greater promise both for the study of adaptation and as a means to identify genes that contribute to agronomically important traits. Expand
Contrasting Patterns in Crop Domestication and Domestication Rates: Recent Archaeobotanical Insights from the Old World
  • D. Fuller
  • Biology, Geography

  • 2007
TLDR
Data suggest that in domesticated grasses, changes in grain size and shape evolved prior to non-shattering ears or panicles, suggesting a need to reconsider the role of sickle harvesting in domestication. Expand
Conservation of gene function in the solanaceae as revealed by comparative mapping of domestication traits in eggplant.
TLDR
The results suggest that domestication of the Solanaceae has been driven by mutations in a very limited number of target loci with major phenotypic effects, that selection pressures were exerted on the same loci despite the crops' independent domestications on different continents, and that the morphological diversity of these four crops can be explained by divergent mutations at these loci.

Genetic Control of the Domestication Syndrome in Common Bean
TLDR
The results suggest that domestication of common bean could have proceeded rapidly and that evolution can proceed through changes involving a few genes with large effect rather than through a gradual accumulation of changes coded by changes with small effects, and that adaptation to rapidly changing environmental conditions may involve genes withLarge phenotypic effects.
