Organization of two homeologous regions between sorghum and sugarcane. Genes are indicated by blue boxes; LTR retroelements by black boxes; SINE retroelements by stripped boxes; LINE retroelements by squared boxes; DNA transposons by arrows; simple repeats by stars; centromeric repeats by oval. a. Comparison between partial sequence of sorghum chromosome 8 and sugarcane BAC 150 M18 contig 6 (showing expanded sorghum sequence). Proteins giving highest BLAST hit of gene1 to 4 are SEU3A protein; thioredoxin M-type, chloroplast precursor; expressed protein; exonuclease family protein, respectively. b. Comparison between partial sequence of sorghum chromosome 6 and sugarcane BAC 204D12 contig 5 (showing expanded sugarcane sequence). Proteins giving highest BLAST hit of the gene1 to 3 are sugar transport protein; hypothetical protein OJ1065_B06.22; and expressed protein, respectively.
