High-resolution comparative analysis between wheat chromosome 3AS and rice chromosome 1, Brachypodium Bd2 and Sorghum chromosome 3. High-density comparative analysis chromosome 3AS BAC end sequences versus the sequenced model grass genomes of rice, Brachypodium and Sorghum. The figure includes two concentric circles. The inner circle represents wheat chromosome 3AS (green) and orthologous chromosomes from rice (blue), Brachypodium (yellow) and Sorghum (red). The outer circle illustrates the heat map and colored bars indicate the density of BLAST hits per mega base of sequence (bin size = 1 Mb). Colored lines in the center represent the putative orthologous relationship between the wheat chromosome 3AS and rice chromosome 1, Brachypodium Bd2 and Sorghum chromosome 3.
