Plant domestication is the process whereby wild plants have been evolved into crop plants through artificial selection. This usually involves an early hybridization event followed by selective breeding.
Apple is one of the most important fruit crops. Here, the authors perform deep genome resequencing of 117 diverse accessions and reveal comprehensive models of apple origin, speciation, domestication, and fruit size evolution as well as candidate genes associated with important agronomic traits.
Emerging research suggests ancient Amazonians employed a range of cultivation practices to develop diversified diets, rich in both wild and domesticated plant and animal resources. Southwestern Amazonia is now understood as a major centre of plant domestication.
For millennia, Chinese knowledge of agriculture and crop breeding influenced the whole world. After an extended period of introspection, Chinese plant biology is once again establishing global eminence.
Whether by accident or design, plants have accompanied people on many historical migrations. It is of little wonder then, that the history of humanity is recorded in the plants whose polysaccharides, proteins and oils keep us alive.
