| Abstract/Contents: | "Transposable elements (TEs) are the main reason for the high plasticity of plant genomes,where they occur as communities of diverse evolutionary lineages. Because research has typi-cally focused on single abundant families or summarized TEs at a coarse taxonomic level, ourknowledge about how these lineages differ in their effects on genome evolution is still rudi-mentary. Here we investigate the community composition and dynamics of 32 long terminal repeatretrotransposon (LTR-RT) families in the 272-Mb genome of the Mediterranean grass Brachypodium distachyon. We ?nd that much of the recent transpositional activity in the B. distachyon genome is dueto centromeric Gypsy families and Copia elements belonging to the Angela lineage. With ahalf-life as low as 66 kyr, the latter are the most dynamic part of the genome and an impor-tant source of within-species polymorphisms. Second, GC-rich Gypsy elements of the Retandlineage are the most abundant TEs in the genome. Their presence explains > 20% of thegenome-wide variation in GC content and is associated with higher methylation levels. Our study shows how individual TE lineages change the genetic and epigenetic constitutionof the host beyond simple changes in genome size." |
