Glaucophyte
Glaucocystis sp.
The Glaucocystaceae are an existing of only five unicellular algal species, strain belonging to the Archaeplastida.
Features
There are unicellular ( monadale ) algae. Your cyanelles called plastids form one of the three known main evolutionary lineages of primary plastids. The cyanelles contain chlorophyll a as accessory pigments occur phycocyanins arranged in phycobilisomes as photosynthetic antennae. The cyanelles are also surrounded by a thin Peptidoglykanwand. This is interpreted in terms of the endosymbiont theory as a rudimentary bacterial cell wall. So there are endosymbiontisch living cyanobacteria. The genome of the cyanelles has one tenth the size of wild cyanobacteria, that is on the order of chloroplasts.
System
The position of the Glaucophyten is not finally resolved. After Thomas Cavalier- Smith, they form a sister group of red algae and with them the Underdark Biliphyta (named after the phycobilins ). Inter alia According to the current classification of Adl 2005 include the Glaucophyten along with the red algae and plants to the Archaeplastida. They contain only four genera with six species:
- Cyanophora Korshikov C. paradoxa
- Cyanophora biloba
- Cyanoptyche gloecystis
- Glaucocystis nostochinearum
- Gloeochaete wittrockiana
- Gloeochaete protogenita
