Biology:Tetrabaenaceae

From HandWiki

Tetrabaenaceae is a family of green algae in the order Chlamydomonadales.[1] It is widespread but occasional, and found in freshwater habitats.[2]

Members of the family Tetrabaenaceae consists of four-celled colonial organisms.[3] Each cell is ovoid and biflagellate (with two equal flagella) and is embedded in a gelatinous matrix. Cells contain a large cup-shaped chloroplast with a basal pyrenoid, a stigma, and two contractile vacuoles at the base of the flagella. Sexual reproduction is isogamous.[2]

The family contains two genera, Tetrabaena and Basichlamys. The two form a clade within the larger phylogroup Reinhardtinia,[4] and were traditionally thought to be sister to the clade containing Volvocaceae and Goniaceae.[5] However, recent phylogenomic evidence suggest that Chlamydomonas reinhardtii and its allies, and Vitreochlamys ordinata are nested within the Tetrabaenaceae+Goniaceae+Volvocaceae clade, rendering it paraphyletic. Therefore, the phylogenetic relationships would be as follows:[6]

Tetrabaenaceae

Vitreochlamys ordinata

Chlamydomonadaceae sensu stricto (Chlamydomonas s.s., Edaphochlamys)

Goniaceae

Volvocaceae
