Phylum of algae / From Wikipedia, the free encyclopedia

Dear Wikiwand AI, let's keep it short by simply answering these key questions:

Can you list the top facts and stats about Ochrophyte?

Summarize this article for a 10 years old


The ochrophytes are is a group of mostly photosynthetic stramenopiles (heterokonts), placed either in phylum Ochrophyta or subphylum Ochrophytina.[5][6][7] Their plastid is of red algal origin.[8][7]

  • Heterokontophyta van den Hoek et al., 1978
  • Ochrista Cavalier-Smith, 1986[2][3]
  • Stramenochromes Leipe et al., 1994[4]

The classification of the group is still being worked out. Originally, the ochrophytes were regarded as a phylum denominated Ochrophyta. Some authors (e.g., Cavalier-Smith) divided it into two subphyla, Phaeista Cavalier-Smith 1995 (comprising Hypogyristea and Chrysista in some classifications, or Limnista and Marista in others) and Khakista Cavalier-Smith, 2000 (comprising Bolidophyceae and diatoms).[9][citation needed] Others prefer not to use the subphyla, listing only lower taxa (e.g., Reviers, 2002, Guiry & Guiry, 2014).[citation needed]

However, it is currently regarded as a subphylum inside of the phylum Gyrista, along with Pseudofungi and Bigyromonada. It contains two infraphyla: Diatomista (containing diatoms and related groups) and Chrysista (containing brown and golden algae and related groups).[7]
