|description=''Grande'' is a LTR retroelement originally characterized in the genome of ''Zea diploperennis'', and known to also be widely distributed in all ''Mais'' chromosomes ([[Literature:85484|Aledo et al. 1995]]). This element belongs to a lineage of plant LTR retrotransposons (''Tat''), sibling of other lineage of putative plant endogenous retroviruses (''Athila''), providing evidence of a shared ancestral lineage originally described as class A by Wright and Voytas ([[Literature:83586|1998]]). The genomic structure of ''Grande'' has several subtypes, subtype 1-4 is taken as representative. The genome structure of this element is 13.8 Kb in size including LTRs of 0.6 Kb. The internal region displays a Primer Binding Site (PBS) complementary to a tRNA <sup>Arg</sup>, three Open Reading Frames (ORFs) for ''gag'', ''pro'', and ''pol'' genes, and downstream to the integrase domain, a non-coding region of approximately 7 Kb in size, which contains two tandem repeats and an ORF that might be transcriptionally active in reverse frame, and also, a Polypurine Tract (PPT) adjacent to the 3´LTR ([[Literature:47700|Martínez-Izquierdo, García-Martínez and Vicient, 1997]]; [[Literature:24455|García-Martínez and Martínez-Izquierdo 2003]]).
