10+ Genomes

Modern wheat cultivars carry a wide range of different genes associated with important traits, such as increased yield and disease resistance. It is impossible to capture all of these genes with a single genome sequence; therefore, additional genome sequences are required. Sequencing multiple wheat genomes will allow for the full complement of wheat genes to be identified, also called the ‘pan genome’. The ‘pan genome’ can be subdivided into two components, the ‘core genome’ and the ‘dispensable genome’. The ‘core genome’ encompasses genes that are common across most or all wheat, while the ‘dispensable genome’ includes genes that are present in only a subset of individuals or are unique to an individual. By capturing the ‘pan’, ‘core’, and ‘dispensable’ genome, wheat researchers and breeders will be better equipped to identify genes that can be used for improving wheat production and quality. It will also aid our understanding of gene-models and regulatory motifs.
