- The application of genomic approaches to the phenomenon of plant domestication promises a better understanding of the origins of agriculture, but also of the way plant genomes in general are organized and expressed. Building on earlier genetic research, 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. In addition, putative domestication genes have been identified through population genomics approaches (selective sweeps or divergence scanning). Further information has been obtained on the origin of domestication syndrome mutations and the dispersal and adaptation of crops after domestication. For the future, increasingly multidisciplinary approaches using combinations of genomics and other approaches will prevail.
