Deletion bin-mapped wheat ESTs on wheat chromosome arm 1AS and estimates of gene density within the bins.

aNumber of wheat ESTs mapped specifically to respective deletion Bin (Sorrels et al., 2003). bNumber of genes in the Brachypodium 1S reference zipper which have homology at the nucleotide level to bin-mapped ESTs. cApproximate range of zipper genes corresponding to wheat deletion bin. dApproximate gene density, assuming the same number of genes for wheat as in the 1AS syntenic region in Brachypodium.
