A highly compartmentalized genome colonized by Chromoviridae-related Gypsy transposons. (A) From outer to inner circles: distribution of transposons, genes, TE hotspots, and TE coldspots across the 17 main contigs of the T. panzhihuanense nuclear genome. (B) Correlation between TE density against gene density across 50 kb nonoverlapping genomic windows; rho = Spearman's rank correlation coefficient. (C) Phylogenetic tree of representative Gypsy RT protein segments longer than 100 amino acids. Green circles highlight crown nodes of identified families with bootstrap support values of 75 or more. (D) Genomic occurrence of the four identified Gypsy clades in the T. panzhihuanense genome.
