From: Karyotype and LTR-RTs analysis provide insights into oak genomic evolution
Evolution and diversity of LTR-RTs lineages in each oak species. a The estimated insertion time of all full-length LTR-RTs (MYA, millions of years ago); b The estimated insertion time of Copia; c The estimated insertion time of Gypsy; d Phylogenetic trees constructed based on reverse transcriptase domain sequences. The different colors on the outer circle represent different species, and the different colors on the Branch represent different lineages
