SIRE1 belongs to SIRE a clade of ''Ty1/Copia'' plant LTR retrotransposons and potential retroviruses ([[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 genome structure of SIRE1-4 (taken as a SIRE1 representative) is 9.8 Kb in size (9805 bp in length) including two long LTRs of 1148 bp ([[Literature:41867|Laten ''et al''. 2003]]). The internal region of this element contains a Primer Binding Site (PBS), complementary to a tRNA&lt;sup&gt;iMet&lt;/sup&gt;, two Open Reading Frames (ORFs) and a Polypurine Tract (PPT). The largest first ORF contains a ''gag-pol'' gene encoding for the tyìcal gag and pol protein domains (gag, protease, integrase, reverse transcriptase and RNase H). This ORF is followed by a second ORF separated by a single stop codon that encodes for a putative env protein ([[Literature:41867|Laten et al. 2003]]). 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=sire1-4.png<br /> |host=Glycine max<br /> |hostpic=Glycine_max.gif<br /> |literature=*[[Literature:15303|Mobile DNA II.
