|description=CRM is a LTR retrotransposon characterized in ''Zea Mays'' ([[Literature:74596|Zhong et al 2002]]).CRM 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]]). In chromoviruses, CRM gives the name and belongs to CRM clade; a centromere-associated sub-lineage characterized for encoding integrases which are clearly divergent from that encoded by other lineages of chromoviruses ([[Literature:26737|Gorinsek, Gubensek and Kordis 2004]]).

The genomic structure of CRM is 7.6 Kb in size, including LTRs of 931 nt. The internal region 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:74596|Zhong et al 2002]]). 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]]).
