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.

a. 特异性定位至对应缺失bin（deletion Bin）的小麦表达序列标签（Expressed Sequence Tag, EST）数目（Sorrels等，2003）。
b. 与经bin定位的表达序列标签在核苷酸水平存在同源性的二穗短柄草（Brachypodium）1S参考拉链（reference zipper）中的基因数目。
c. 与小麦缺失bin对应的参考拉链基因的大致区间范围。
d. 假设小麦的基因数目与二穗短柄草中对应小麦1AS染色体臂的共线性区域（syntenic region）的基因数目一致时的近似基因密度。
