Observation of Photobehavior in Chlamydomonas reinhardtii.

For the survival of the motile phototrophic microorganisms, being under proper light conditions is crucial. Consequently, they show photo-induced behaviors (or photobehavior) and alter their direction of movement in response to light. Typical photobehaviors include photoshock (or photophobic) response and phototaxis.

Cilia Loss and Dynein Assembly Defects in Planaria Lacking an Outer Dynein Arm-Docking Complex Subunit.

The outer dynein arm-docking complex (ODA-DC), which was first identified in the green alga , is a protein complex that mediates the binding of axonemal dynein and doublet microtubules. To gain a better understanding of the evolutionary conservation and functional diversity of the ODA-DC, we knocked down a homolog of DC2, a major subunit of the ODA-DC, in the planarian . Planaria are carnivorous flatworms that move by beating cilia on their ventral surface against a secreted mucus layer.
