Fig. 2From: Genomic adaptations to chemosymbiosis in the deep-sea seep-dwelling tubeworm Lamellibrachia luymesiLamellibrachia luymesi lacks amino acid biosynthesis genes. a The presence (green) or absence (white boxes) of key genes associated with amino acid biosynthesis in the genomes of Capitella teleta, L. luymesi, and L. luymesi symbionts. The asterisks represent genes present in C. teleta and L. luymesi gammaproteobacterial symbionts but absent in L. luymesi. b Aspartate and glutamate biosynthesis pathways as an example of a modified pathway in L. luymesi. Blue lines represent key enzymes present in C. teleta and L. luymesi symbionts but absent in L. luymesi. Enzymes only present in L. luymesi symbionts are in red boxes.
