Orthologous chromosomal locations of selected 20 sugarcane BACs on each chromosome arm of the 10 sorghum chromosomes. The solid line represents the sorghum chromosome. The red rectangle represents the sugarcane BACs. The locations of the BACs were based on the overgo probe hits on the sorghum scafold sequence. The BAC 79A20 was corresponding to an arm of the sorghum chromosome 9 in an earlier version of the assembly when we started the work and it, and it was on chromosome 1 in the final version of the sorghum genome assembly.
