On the Trail of Tetu1: Genome-Wide Discovery of CACTA Transposable Elements in Sunflower Genome.

ABSTRACT: Much has been said about sunflower (Helianthus annuus L.) retrotransposons, representing the majority of the sunflower's repetitive component. By contrast, class II transposons remained poorly described within this species, as they present low sequence conservation and are mostly lacking coding domains, making the identification and characterization of these transposable elements difficult. The transposable element Tetu1, is a non-autonomous CACTA-like element that has been detected in the coding region of a CYCLOIDEA (CYC) gene of a sunflower mutant, tubular ray flower (turf). Based on our knowledge of Tetu1, the publicly available genome of sunflower was fully scanned. A combination of bioinformatics analyses led to the discovery of 707 putative
