An example of duplicated gene fusion. Region 698,000-710,000 of chromosome 5. In this TA, four TUs match coding genes. The two remaining TUs appear each in a single fusion gene that has apparently been built by merging successive duplication units. The A. thaliana EST clusters (extracted from Gramene web site, Ensembl Plants Arabidopsis thaliana version 62.10), mapped to the region on the Gramene web site, effectively confirm the existence of an intron in this gene connecting the two duplicated regions.
