Picophagea, also known as Synchromophyceae, is a class of photosynthetic stramenopiles.[1][3][4] The chloroplast of the Synchromophyceae are surrounded by two membranes and arranged in a way where they share the outer pair of membranes. The entire chloroplast complex is surrounded by an additional two outer membranes.[2]
Evolution
[edit]Synchromophyceae or Picophagea is a clade within the Ochrophyta that contains a few genera of amoeboid organisms such as the mixotrophic Synchromonas and the heterotrophic Chlamydomyxa, Leukarachnion and Picophagus.[5] It is phylogenetically close to the classes Chrysophyceae and Eustigmatophyceae, within the SII clade.[6]
Taxonomy
[edit]According to AlgaeBase, the class contains only two genera:[7]
- Class Picophagea Cavalier-Smith 2006 emend. 2017 [=Synchromophyceae S.Horn & C.Wilhelm 2007]
- Order Synchromales Horn & Ehlers 2007
- Family Synchromaceae Schnetter & Ehlers 2007
- Genus Synchroma Schnetter 2007
- Family Synchromaceae Schnetter & Ehlers 2007
- Order Chlamydomyxales
- Family Chlamydomyxaceae
- Genus Chlamydomyxa Archer 1875
- Family Chlamydomyxaceae
- Order Synchromales Horn & Ehlers 2007
However, the latest revision recognizes an additional four genera: Chrysopodocystis, Guanochroma, Leukarachnion and Picophagus.[1]
