Extended Data Fig. 2: Comparative genomic analysis of barnacles and other arthropods.
From: New genes helped acorn barnacles adapt to a sessile lifestyle
a, The distribution of divergence of transposable elements (TEs) of eight crustaceans. SINE/LINE: short/long interspersed nuclear element; LTR: long terminal repeat; DNA: DNA transposon. b, The expanded (red) and contracted (blue) gene families, and the frequency distribution of synonymous substitution rates (Ks) between pairwise paralogues for nine crustaceans and the outlier species. c, The 604 expanded families in the common ancestor of barnacles were filtered, where families with a total gene count across these species of less than five were excluded, resulting in 26 gene families. The top nine gene families are listed in Fig. 1d. Abbreviations: Grik2, glutamate receptor ionotropic, kainate 2; mGluR, metabotropic glutamate receptor; nAChRs, nicotinic acetylcholine receptors; Tuba, tubulin alpha chain; Tubb, tubulin beta chain; FT, cadherin-related tumor suppressor; STS, steryl-sulfatase; SPR, sex peptide receptor; Tmem2, transmembrane protein 2; Setd1, histone-lysine N-methyltransferase; Tret1, facilitated trehalose transporter; FucTC, alpha-(1,3)-fucosyltransferase C; WFDC3, WAP four-disulfide core domain protein 3.
