Evolution of and horizontal gene transfer in the Endornavirus genus.

The transfer of genetic information between unrelated species is referred to as horizontal gene transfer. Previous studies have demonstrated that both retroviral and non-retroviral sequences have been integrated into eukaryotic genomes. Recently, we identified many non-retroviral sequences in plant...

Previous studies have demonstrated that both retroviral and non-retroviral sequences have been integrated into eukaryotic genomes.
