|description=''Bagy-2'' is a LTR retroelement originally described along with other retrotransposons in the genome of ''Hordeum vulgare''. This element belongs to ''Athila'' clade, a lineage of possible retroviruses in plants ([[Literature:83585|Wright and Voytas 2002]]), which is sibling of ''Tat'' clade, a lineage of plant LTR retrotransposons. Both lineages provide evidence of a shared ancestral lineage originally described as Class A by Wright and Voytas ([[Literature:83586|1998]]). From a study focused on the mechanisms of retroelement-driven genome expansion counteractions, ''Bagy-2'' was established as a continuum of 10 Kb interrupted and arranged as multiple nested insertions within a heterochromatic region. The figure below depicts the consensus structure of ''Bagy-2'' in which both LTRs flank a reconstructed internal region that presents a Primer Binding Site (PBS) complementary to a tRNA<sup>Asp</sup>, a single Open Reading Frame (ORF) ''gag-pol'', two Polypurine Tracts, PPT1 and PPT2 ([[Literature:69464|Shirasu et al. 2000]]; [[Literature:83585|Wright and Voytas 2002]]), and also, an additional ''env'' gene which undergoes splicing to generate a subgenomic env product ([[Literature:80118|Vicient, Kalendar and Schulman 2001]]).
