Overview of the microcollinearity between C. canephora 46C02 BAC and genomic regions in Arabidospsis ( Arabidopsis thaliana ), tomato ( S. lycopersicon ), Medigago ( Medicago truncatula ), grapevine ( V. vinifera ) and black cottonwood ( Populus trichocarpa ) genomes. Colored arrows with names indicate orientation of predicted coding regions. Stars indicate transcribed genes as suggested by strong EST similarities (see Additional file 1). Colored lines link putative orthologous genes between collinear regions and distances between the most distant collinear genes with C. canephora BAC are indicated in each conserved fragment. Black arrows indicate non-conserved predicted genes. S. lycopersicon is a fragment (51–75 kb) of the Le_HBa0008H22 BAC clone located on chromosome 4. V. vinifera is a part of the scaffold127 of 1,150 kb long.Medicago truncatula indicates a fragment covered by two BAC clones (AC146861, AC173834). Populus trichocarpa corresponds to two fragments located in the linkage group XIII (3,073–3,289 kb) and in the unlinked scaffold 201 and Arabidopsis thaliana to two conserved fragments on chromosome III (A: 1,221–1,241 kb and B: 8,255–8,310 kb). Brackets link identify intra-genomic duplicated regions. The fragment sizes are not to scale.
