Selection on grain shattering genes and rates of rice domestication.
Molecular cloning of major quantitative trait loci (QTLs) responsible for the reduction of rice grain shattering, a hallmark of cereal domestication, provided opportunities for in-depth investigation of domestication processes. Here, we studied nucleotide variation at the shattering loci, sh4 and qSH1, for cultivated rice, Oryza sativa ssp. indica and Oryza sativa ssp. japonica, and the wild pr...
متن کاملQuantitative Trait Locus Analyses of the Domestication Syndrome and Domestication Process
Domestication of many of today’s main food crops occurred approximately 10,000 years ago with the beginning of agriculture. It has lead to the selection by farmers of a wide range of morphological and physiological traits that distinguish domesticated crops from their wild ancestors. These characteristics are collectively referred to as the domestication syndrome and include changes in plant ar...
متن کاملThe domestication process and domestication rate in rice: spikelet bases from the Lower Yangtze.
The process of rice domestication occurred in the Lower Yangtze region of Zhejiang, China, between 6900 and 6600 years ago. Archaeobotanical evidence from the site of Tianluoshan shows that the proportion of nonshattering domesticated rice (Oryza sativa) spikelet bases increased over this period from 27% to 39%. Over the same period, rice remains increased from 8% to 24% of all plant remains, w...
متن کاملUnderstanding rice domestication and implications for cultivar improvement.
Considerable insights were recently gained into the history and process of rice domestication. It becomes increasingly clear that artificial and natural selections coupled with extensive introgression have shaped the genomes of cultivated rice. The interplay of these evolutionary forces gave rise to the cultivated species, Oryza sativa, with divergent genomic backgrounds from two wild species, ...
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...
