Fig. 9From: Features of a novel protein, rusticalin, from the ascidian Styela rustica reveal ancestral horizontal gene transfer eventAlignment of seven Ciona intestinalis tRNA genes neighboring rusticalin-like gene coding sequence. Asterisks indicate conservative positions. Three of the tRNA genes differ from the other tRNA genes at four nucleotide positions (shaded grey). The sequence identity is 95–100%Back to article page
