Supplementary figure 2. Distribution of expression pattern on wheat chromosomes. A consensus expression map of 1030 ESTs with three structural copies physically localized to chromosome regions bracketed by wheat deletion breakpoints. The maps were drawn using the information from Qi et al. 2004. Fraction length for each chromosomal regions is given on the left side of the chromosomes and the genes are given on the right. Statistical significance was tested at p
