Artificial Selection in Domestication and Breeding Prevents Speciation ...
Apr 6, 2020 · This counteracting system indicates that combined effects of natural evolution and artificial selection may result in reversible processes of speciation in rice, which may also have implications for genetic improvement of rice.
The rice genome revolution: from an ancient grain to Green Super Rice
Jun 5, 2018 · This study identified ~200 regions that contained signatures of domestication or artificial selection and which spanned 7.8% of the rice genome. These regions harbour around 4,000...
Genomic selection: A breakthrough technology in rice breeding
Jun 1, 2021 · Genomic selection (GS) holds a great potential to accelerate breeding progress and is cost-effective via early selection before phenotypes are measured. Previous simulation and experimental studies have demonstrated the usefulness of GS in rice breeding.
Understanding rice domestication and implications for cultivar ...
May 1, 2013 · Artificial and natural selection coupled with introgression shaped the rice genome. Cultivated rice and wild progenitors possess alleles for cultivar improvement. Domestication analysis is instructive to the discovery of valuable alleles.
Artificial selection in the expansion of rice cultivation
Nov 3, 2021 · Gene distributions and population genomics suggest artificial selection of ghd7 osprr37, for extremely early heading date of rice, in the Tohoku region of Japan. The ranges of cultivated crops expanded into various environmental …
The evolutionary process of ORF4 could be traced based on the ORF4+ allelic groups in the japonica rice and the ORF4 allelic groups in the indica rice (Figure 1). ORF4+(9) existed in 16.7% of the wild species and 79.2% of the japonica rice; this allele was likely the most ancestral type that generated other clades.
The Process of Rice Domestication: A New Model Based on …
Oct 29, 2008 · The DNA changes involved in rice domestication could be generally considered as targets for artificial selection by ancient humans. It is likely that they were selected either as new mutations occurring naturally in the groups of plants subjected to domestication or by introgression of standing variation (pre-existing mutations) from wild ...
Artificial selection for a green revolution gene during japonica rice ...
Jul 5, 2011 · These findings indicate that SD1 has been subjected to artificial selection in rice evolution and that the FNPs participated in japonica domestication, suggesting that ancient humans already used the green revolution gene.
Artificial Selection in Domestication and Breeding Prevents …
Apr 6, 2020 · This counteracting system indicates that combined effects of natural evolution and artificial selection may result in reversible processes of speciation in rice, which may also have implications for genetic improvement of rice.
Two Evolutionary Histories in the Genome of Rice: the Roles of
Jun 9, 2011 · If selection has affected the genomes of cultivated rice, this will have to be determined from the patterns of genetic variation within LDRs. To tease apart the evolutionary forces that influence LDRs, we took advantage of the existence of two subspecies of domesticated rice.
