Background: Transposable elements (TEs) in eukaryote genomes arequantitatively the main components affecting genome size, structure andexpression. The dynamics of their insertion and deletion depend on diversefactors varying in strength and nature along the genome. We address here how TEsequence evolution is affected by neighboring genes and the chromatin status(euchromatin or heterochromatin) at their insertion site. Results: We estimatedages of TE sequences in Arabidopsis thaliana, and found that they depend on thedistance to the nearest genes: TEs located close to genes are older than thosethat are more distant. Consequently, TE sequences in heterochromatic regions,which are gene-poor regions, are surprisingly younger and longer than thatelsewhere. Conclusions: We provide evidence for biased TE age distributionclose or near to genes. Interestingly, TE sequences in euchromatin and those inheterochromatin evolve at different rates, and as a result, could explain thatTE sequences in heterochromatin tend to be younger and longer. Then, we revisitmodels of TE sequence dynamics and point out differences for TE-rich genomes,such as maize and wheat, compared to TE-poor genomes such as fly and A.thaliana.
