Biased patterns of expression for homoeoloci on wheat group 1 and 5 chromosomes. (A) The number of genes expressed from all three homoeoloci in euploid wheat showing either equal expression (‘A = B = D’), a consistent and significant pattern of differential expression bias (e.g., ‘B > A = D’) or classified as unknown (i.e., lack of consistent pattern of significant expression bias) for genes on chromosome groups 1 and 5, in shoot and root tissues. (B) The number of genes in roots (light blue) and shoots (dark blue) showing each pattern of differential homoeolocus expression. (C) The mean percentage of total transcripts arising from A, B and D homoeoloci for 12 distinct patterns of differential homoeolocus expression in roots (for shoots see Additional file 8: Figure S6). Error bars (-) are given at one standard deviation above and below the mean.
