Genomic arrangement of omega gliadin genes on chromosomes 1A (a), 1B (b) and 1D (c) of Chinese Spring summarized from [11]. The positions of ancestral genes found on all three chromosomes are indicated with black dots. Genes with repetitive motifs characteristic of omega-5 and omega-1,2 gliadins are shown in red and blue ovals, respectively. Predicted N-terminal sequences of the encoded proteins are shown above each group of genes. Genes that encode full length omega gliadins are denoted by solid ovals, pseudogenes by open ovals and truncated genes by hatched ovals. If expressed, truncated genes are predicted to encode proteins missing a portion of the COOH terminus. The truncated gene on chromosome 1A is located outside the 5.3 Mb region that was annotated
