Abstract
- Endogenous viral elements (EVEs) have been for the most part described in animals and to a less extent in plants. The endogenization was proposed to contribute toward evolution of living organisms via horizontal gene transfer of novel genetic material and resultant genetic diversity. During the last two decades, several full-length and fragmented EVEs of pararetroviral and non-retroviral nature have been identified in different plant genomes, both monocots and eudicots. Prior to this work, no EVEs have been reported in alfalfa (Medicago sativa L.), the most cultivated forage legume in the world. In this study, taking advantage of the most recent developments in the field of alfalfa research, we have assessed alfalfa genome on the presence of viral-related sequences. Our analysis revealed segmented EVEs resembling two dsDNA reverse-transcribing virus species: Soybean chlorotic mottle virus (family Caulimoviridae, genus Soymovirus) and Figwort mosaic virus (family Caulimoviridae, genus Caulimovirus). The EVEs appear to be stable constituents of the host genome and in that capacity could potentially acquire functional roles in alfalfa’s development and response to environmental stresses.
