Asteraceae Genomic Research Platform
Transposable elements (TEs): also known as jumping genes, are DNA sequences that can change their position in a cell. There are two types of transposons: type I transposons (Retrotransposon) and type II transposons (DNA transposons).
Class I (Retrotransposons): A class of transposons that insert into the genome via reverse transcription of an RNA intermediate, including LTR (Long Terminal Repeat) and non-LTR (Long Terminal Repeat-less) subclasses such as Copia, Gypsy (LTR), LINE, and SINE (non-LTR). Class II (DNA transposons): Transposons that undergo “cut-and-paste” transposition directly in DNA form, encompassing multiple superfamilies (e.g., CACTA, Harbinger, hAT) and short subtypes like MITEs (miniature inverted-repeat transposable elements).
We detected a total of 187,648,748 TEs across 53 Asteraceae species and 6 outgroups.
