Proteorhodophytina

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

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 which contrasts with the generally compact and slow-evolving plastid genomes of other rhodophytes. Mitochondrial genomes of Proteorhodophytina are also larger than in other groups of red algae.
