|description=''MarY1'' is a LTR retrotransposon characterized in ''Tricholoma matsutake'' ([[Literature:52911|Murata and Yamada 2000]]). It 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]]). This 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 ''marY1'' is 6.8 Kb in size, including LTRs of 425 nt. Its internal region displays Primer Binding Site (PBS), three Open Reading Frames (ORFs) containing gag, protease (Pro) and pol domains, and a Polypurine Tract (PPT) adjacent to the 3´LTR ([[Literature:52911|Murata and Yamada 2000]]). This element presents a detectable chromodomain (CHR) at the C-terminal end of the integrase (INT) 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]]).
