|description=''Galadriel'' is a LTR retrotransposon described in ''Lycopersicon esculentum'' ([[Literature:85452|Parniske et al. 1999]]). ''Galadriel ''belongs to the ''Chromoviridae'' branch, term suggested ([[Literature:47259|Marín and Lloréns 2000]]) to describe the ''Ty3/Gypsy'' elements bearing chromodomain-integrases ([[Literature:46552|Malik and Eickbush 1999]]). The chromovirus branch is probably the most ancient phylogenetic pattern of ''Ty3/Gypsy'' retroelements ([[Literature:26737|Gorinsek, Gubensek and Kordis 2004]]; [[Literature:26736| 2005]]; [[Literature:39523|Kordis 2005]]).

The genomic structure of ''Galadriel'' is 6.2 Kb in size, including LTRs of 0.8 Kb. The internal region of this element displays a Primer Binding site (PBS), a single Open Reading Frame (ORF) gag-pol, and a Polypurine Tract (PPT) adjacent to the 3´LTR ([[Literature:85452|Parniske et al. 1999]]; [[Literature:47259|Marín and Lloréns 2000]]). This element presents a detectable chromodomain at the C-terminal end of the integrase domain. The PBS of fungi and vertebrate chromoviruses, differs significantly from that used by plant chromoviruses. While plant chromoviruses use a methionine starting tRNA (iMet), fungi and vertebrate chromoviruses use their own self-priming mechanism to start the reverse transcription ([[Literature:43217|Levin 1995 ]]; [[Literature:10125|Butler et al. 2001]]).
