Table 1 Natural variation in ASN proteins in 14 wheat varieties. Each gene is annotated by name [14, 15] and genome (hence TaASN-A1, for example, is the A genome TaASN1 gene), and the gene ID from the Chinese Spring RefSeq v1.1 gene models [18] (note that TaASN-B2 is absent in Chinese Spring). Green shading indicates no predicted impact of variety-specific mutations; yellow shading indicates one or more mutations that are predicted to disrupt protein function; red shading indicates that the gene is not present in that genome.
