Proteorhodophytina is a subdivision of red algae containing unicellular, pseudofilamentous, and filamentous photosynthetic eukaryotes. ^[1]

Taxonomy

• Class Compsopogonophyceae G. W. Saunders & Hommersand
• Class Porphyridiophyceae M. Shameel
• Class Rhodellophyceae Cavalier-Smith
• Class Stylonematophyceae H. S. Yoon, K. M. Müller, R. G. Sheath, F. D. Ott & D. Bhattacharya

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]
