''Lycopersicon esculentum'') ([[Literature:59075|Peterson-Burch and Voytas, 2002]]; [[Literature:29886|Havecker ''et al.'' 2005]]). ToRTL1 belongs to the SIRE clade of ''Ty1/Copia'' plant LTR retrotransposons and potential retroviruses ([[Literature:59075|Peterson-Burch and Voytas, 2002]]; [[Literature:29886|Havecker ''et al.'' 2005]];[[Literature:100589|Fauquet ''et al.'' 2005]]) evolutionarily related to another clade of plant ''Ty1/Copia'' LTR retrotransposons called ''Oryco'' ([[Literature:100596|Llorens ''et al''. 2009]]). SIRE clade gives the name to a genus within the current ICTV classification of the ''Ty1/Copia'' into three genera – Pseudovirus, Hemivirus and Sirevirus ([[Literature:100591|Boeke ''et al''. 2005]]). <br /> <br /> The full-lenght genome of ToRTL1 is 9688 bp in size, including LTRs of 808 (5’LTR) and 809 (3’LTR) bps long. The internal region contains a Primer Binding Site (PBS) complementary to a tRNA&lt;sup&gt;iMet&lt;/sup&gt;, a coding region and a Polypurine Tract (PPT) upstream its 3’LTR. The coding region presents three Open reading frames (ORFs) that, although are disrupted by several stop codons and frameshiftings, show the distinct ''gag'', ''pol'' and ''env''-like genes characteristic of ''Sire'' elements ([[Literature:59075|Peterson-Burch and Voytas, 2002]]; [[Literature:29886|Havecker ''et al.'' 2005]]). In comparison to other ''Ty1/Copia'' elements, a taxonomically relevant feature specific of ''Sire''-like elements is their extremely large gag c-terminus consistent with the NC domain, which may display two or three CCHC arrays ([[Literature:100596|Llorens ''et al''. 2009]]). <br /> |structure=ToRTL1.png<br /> |host=Lycopersicon esculentum<br /> |hostpic=Solanum_lycop.jpg<br /> |literature=*[[Literature:15303|Mobile DNA II.
