- Abstract
A lineage of CACTA family transposons has been identified in temperate grasses and cereals, and a full-length representative of the subfamily from Lolium perenne has been sequenced. Both the size and internal organization of the L. perenne element are typical of other CACTA family elements but its high copy number and strong conservation are unexpected. Comparison with homologs in other species suggests that this lineage has adopted a distinct and novel evolutionary strategy, which has allowed it to maintain its presence in genomes over long periods of time.
