Fig. 1From: Evolution of group I introns in Porifera: new evidence for intron mobility and implications for DNA barcodingSimplified sponge phylogeny highlighting currently known group I and II intron insertion sites. Horizontal black lines with colored vertical bars and numbers (blue: intron 723, green: intron 870, red: intron 714, brown: intron 387, purple: intron 966, pink: intron 1141) behind the taxa names represent different intron locations within cox1 Back to article page
