Structure and conservation of the KCS17-FAE1 intergenic region in Camelina sativa. The three putative homoeologous regions in C. sativa are aligned to the orthologous region of Arabidopsis to display blocks of homology identified on a dot matrix by perfect conservation of a sliding window of 9 bases. The KCS17 and FAE1 gene, respectively blue and red, flank a variable region in which potentially related sequences are marked by different shades of brown, corresponding to varying levels of similarity, which were estimated visually from dot matrix plots since proper alignment was not possible. Lined regions display reduced or no conservation. The large variation in the intergenic region of the triplicated KCS17-FAE1 DNA of C. sativa is consistent with independent evolution before reunion of diverged genomes by polyploidization.
