Abstract:

Wheat is now the first food crop all over the world, and its wide spread adaptation and improved quality are mainly due to the integration of D genome into tetraploid wheat. Aegilops tauschii is the donor of D genome in common wheat. Here, we introduced briefly the structure of D genome, then primarily focused on the application of wheat genome sequencing on wheat studies, such as gene discovery, germplasm diversity and haplotyping, variety improvement, comparative genomics, genome evolution and polyploidization. We also gave some suggestions for future researches on wheat genome in China.

Key words: wheat, D genome, draft sequence, application
