Length distribution and phylogenetic trees of LTRs. a Length distribution of complete LTRs (green whiskers and black boxes represent average length distribution, and white circles represent median). b Copia-like superfamily RT domain phylogenetic tree. c Gypsy-like superfamily RT domain phylogenetic tree. Citrus also keeps six Gypsy lineages (reference LTR retrotransposons are shown as italic with circles on branches, others are LTR families in Citrus)
