Agriculture is an outcome of the interaction between the human and the nature with the ultimate goal to achieve the best gain in yield. Wheat as an allohexaploid evolves in a unique manner for yield increase in nature and, although, as a member of the monocotyledon family, it also follows general mechanisms during human selection. With the advance of sequencing technologies, the available of the wheat genomes, and various genomic tools, our understanding of wheat yield component is rapidly increasing although the current resolution is still quite low. In this talk, I will cover several developments in the genomics point of views that may contribute to wheat yield improvement, especially during the wheat genome polyploidization, domestication, and human selection.
