Description of Pycnococcaceae

provided by BioPedia
Marine picoplanktonic, unicellular (rarely colonial), surrounded by a wall, and lack flagella; a channel in the pyrenoid contains a protrusion from the mitochondrion, a very unusual character shared with the flagellated prasinophyte Pseudoscourfieldia; studies on the Rubisco-gene have confirmed phylogenetic relationship between these coccoid species and Pseudoscourfieldia.

Pycnococcaceae

provided by wikipedia EN

Pycnococcaceae is a family of green algae in the order Pseudoscourfieldiales.[1] The defining features of this family include the single invagination of the pyrenoid where the mitochondrial membrane fits into it [2] and the "decapore" - a ring of 10 pores through the thick cell wall.[3]
