Escape to Ferality: The Endoferal Origin of Weedy Rice from Crop Rice through De-Domestication
Domestication is the hallmark of evolution and civilization and harnesses biodiversity through selection for specific traits. In regions where domesticated lines are grown near wild relatives, congeneric sources of aggressive weedy genotypes cause major economic losses. Thus, the origins of weedy genotypes where no congeneric species occur raise questions regarding management effectiveness and ...
متن کاملGenomic variation associated with local adaptation of weedy rice during de-domestication
De-domestication is a unique evolutionary process by which domesticated crops are converted into 'wild predecessor like' forms. Weedy rice (Oryza sativa f. spontanea) is an excellent model to dissect the molecular processes underlying de-domestication. Here, we analyse the genomes of 155 weedy and 76 locally cultivated rice accessions from four representative regions in China that were sequence...
متن کاملMapping of seed shattering loci provides insights into origin of weedy rice and rice domestication.
Seed shattering is an important trait that distinguishes crop cultivars from the wild and weedy species. The genetics of seed shattering was investigated in this study to provide insights into rice domestication and the evolution of weedy rice. Quantitative trait locus (QTL) analysis, conducted in 2 recombinant inbred populations involving 2 rice cultivars and a weedy rice accession of the sout...
متن کاملRice domestication by reducing shattering.
Crop domestication frequently began with the selection of plants that did not naturally shed ripe fruits or seeds. The reduction in grain shattering that led to cereal domestication involved genetic loci of large effect. The molecular basis of this key domestication transition, however, remains unknown. Here we show that human selection of an amino acid substitution in the predicted DNA binding...
متن کاملEvolution during Domestication
Domestication is a genetic selection process exerted – consciously or unconsciously – by humans to adapt wild plants andanimals to cultivation andherding, respectively. Because of this process, major crops and domesticated breeds arose,whichwere not only easier to cultivate or herd but also more appealing to consume or process for further uses. During domestication, plants and animals are subje...
