^a Number of markers assigned to the deletion bins; ^bnumber of contigs assigned to the deletion bins; ^ccumulated size of the assigned contigs in Mb; ^dtotal number of markers in the assigned contigs; ^enumber of genes in the assigned contigs; ^fthe gene density in genes per Mb was estimated in each bin using the number of genes anchored divided by the cumulated contigs size; ^ggenes not conserved in syntenic regions of rice, Brachypodium or sorghum are indicated for each bin; ^hthe number of gene islands was calculated for each bin using the number of genes in the same BAC or overlapping BACs in each bin.
