Fig. 3: Expansion of transposable elements and genome size variation in notothenioid genomes.
From: Genomics of cold adaptations in the Antarctic notothenioid fish radiation
a Species analysed, including 16 species sequenced in this study, and two previously published genomes (E. maclovinus32, and D. mawsoni57). b Repeat landscape plots showing the distribution of transposable element copies as percentage of divergence from consensus repeat models (x-axis, Kimura divergence) versus genome coverage (y-axis). Colours represent different TE classes. The red arrow indicates the timing of the earliest TE expansion identified in our analysis. c Correlation of repeat content with genome size (Pearson Correlation Coefficient, n = 16, R = 0.95, two-sided p = 1.647e-08, slope = 0.99), an increase of repeat fraction with genome size, and increase of DNA, LINE, and LTR TE classes with genome size. The shaded zone indicates 95% confidence interval. The plot was generated using package ggplot2 and function ggpubr99. Double forward slashes in the time axis indicate a cropped line in the tree branches. Source data are provided as a Source Data file.
