Retrotransposons with long terminal repeats (LTRs) more than 3 kb are not frequent in most eukaryotic genomes. Rice LTR retrotransposon, Retrosat2, has LTRs greater than 3.2 kb and two open reading frames (ORF): ORF1 encodes enzymes for retrotransposition whereas no function can be assigned to ORF0 as it is not found in any other organism. A variety of experimental and in silico approaches were used to determine the origin of Retrosat2 and putative function of ORF0. Our data show that not only is Retrosat2 highly abundant in the Oryza genus, it may yet be active in rice. Homologs of Retrosat2 …
