Tyl6, a novel Ty3/gypsy‐like retrotransposon in the genome of the dimorphic fungus Yarrowia lipolytica

Abstract: The novel LTR retrotransposon Tyl6 was detected in the genome of the dimorphic fungus Yarrowia lipolytica. Sequence analysis revealed that this element is related to the well-known Ty3 element of Saccharomyces cerevisiae and, especially, to the recently described Tse3 retrotransposon of Saccharomyces exiguus and to the del1-like plant retrotransposons. Tyl6 is 5108 bp long, is flanked by two identical long terminal repeats (LTR), each of 276 bp, and its ORFs are separated by a −1 frameshift. Both ORFs are inta… Show more

“…As noted above, CLIB122 was derived from a cross between French strain CLIB89 and American strain CBS6124-2. Amazingly, CLIB89 YALI1 and CLIB89-derived PO1f completely lack both full-length and solo LTR copies of Ylt1 and Tyl6 based on hybridization, draft assembly and complete sequence analysis [19, 44, 45] (this study). However, it has four copies of Tyl3 LTRs three of which are allelic with copies in CLIB122 and 54 copies of LTRyl1 thirty of which are allelic with copies in CLIB122 YALI0.…”

“…Little data are currently available on the differences between geographically distinct populations. A clear difference between American and European isolates has been observed for the distribution of the Tyl6 gypsy retrotransposon, which seems to be of American origin (Kovalchuk et al, 2005). Insertion sites of the line retrotransposon Ylli are conserved in sympatric populations (S. Casaregola, unpublished data), also supporting the existence of a geographic organization of wild populations.…”

“…In addition, the presence of an internal translation site provides a normal translation of the pol gene in the case of individual elements, which have stop codons within the gag gene. Another possible variant is when the mRNA region, located between gag and pol genes, can contain a small repeated motif (for example, AAAAA), causing the slippage of a ribosome and the translation of the second ORF (Jin and Bennetzen, 1989;Gao et al, 2003;Kovalchuk et al, 2005). This mechanism is very common in plant viruses (Giedroc et al, 2000).…”
