Figure 6.
The expansion and contraction of TEs in the 14 arthropod species. (a) The ratio of TE load change (the offspring relative to the ancestral node) for each branch. (b) The dynamic evolutionary rates of TE loads in the phylogeny. Branch colors are scaled by evolutionary rates of TE loads, and rate increases from the cold color (blue) to warm color (red). TIR, terminal inverted repeat; LTR, long terminal repeat; LINE, long interspersed nuclear element; SINE, short interspersed nuclear element.
