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

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]

Ochrophyta

Taxonomy

According to AlgaeBase, the class contains only two genera:[7]

However, the latest revision recognizes an additional four genera: Chrysopodocystis, Guanochroma, Leukarachnion and Picophagus.[1]
