Phylogenetic position of the Oedogoniales within the green algae (Chlorophyta) and the evolution of the absolute orientation of the flagellar apparatus

The order Oedogoniales is made up of green algae with an unusual form of cytokinesis, a ring of flagella on the zoids, and a complex sexual reproduction. The genera included in this order, Oedogonium, Oedocladium and Bulbochaete, differ in their type of habit. In this contribution we report a phylog...
