Welcome to the PGSB Wheat Genome (IWGSC) Database

The analysis of the complex, high-repetitive hexaploid wheat genome is an international effort coordinated by the IWGSC.
The International Wheat Genome Sequencing Consortium (IWGSC) focused on sequencing individual wheat chromosome arms to provide high quality reference sequences, which can be used to explore and understand the structure, function and evolution of the bread wheat genome.

 

We published a series of research manuscripts on the chromosome-based draft provides new insight into the structure, organization, and evolution of the large, complex genome of the world's most widely grown cereal crop, bread wheat. The manuscripts have been published in the July, 18th 2018 special issue of science.

The draft sequence is a major landmark towards obtaining a complete reference sequence of the hexaploid bread wheat genome and gives unparalleled insights into the genomic basis of a polyploid cereal crop. E.g. it is providing new insights into the history and evolution of the wheat genome and genes involved in grain development, as exemplified in two additional publications appearing in the same issue of Science.

With a chromosome-based full sequence in hand, plant breeders will have high quality tools at their disposal to accelerate breeding programs and to identify how genes control complex traits such as yield, grain quality, disease, pest resistance, or abiotic stress tolerance. They will be able to produce a new generation of wheat varieties with higher yields and improved sustainability to meet the demands of a growing world population in a changing environment.
