Genomics

Plastid genomes of Proteorhodophytina are large, highly diversified, and intron-rich^[1] which contrasts with the generally compact and slow-evolving plastid genomes of other rhodophytes.^[2] Mitochondrial genomes of Proteorhodophytina are also larger than in other groups of red algae.^[3]
