From: Group I introns and associated homing endonuclease genes reveals a clinal structure for Porphyra spiralis var. amplifolia (Bangiales, Rhodophyta) along the Eastern coast of South America

Figure 3

Median-joining networks: A – Introns + homing endonuclease gene (HEG); B – and introns without HEG; C – Cox 2-3 region. Circles indicate sequence types and circle sizes are proportional to haplotype frequency. Lines indicate substitutions (not on scale). MV- median vector, H- haplotype. Haplotypes were not plotted on intron without HEG network.
