—An example of TRs contributing to bumblebee coding sequence variation. (A) Pairwise alignments of TR arrays between Bombus terrestris and B. impatiens. Colored letters indicate TR array sequences, while black letters show their flanking sequences. The TR array has a repeat unit of CAG, and there are five more repeat units in B. terrestris than in B. impatiens. The coordinate for the variable TR is NC_015770.1: 2190704–2190753 in B. terrestris. (B) Pairwise alignments of protein sequences encoded by genes containing the variable TR. Colored letters indicate TR array sequences, while black letters show their flanking sequences. There are five more glutamine residues (Q) in B. terrestris than in B. impatiens. Genes containing this variable TR encode nuclear receptor corepressor (protein IDs are XP_012166765.1 and XP_012249688.1 in B. terrestris and B. impatiens, respectively).
