The involvement of a protein kinase in phototaxis and gravitaxis of Euglena gracilis

The unicellular flagellate Euglena gracilis shows positive phototaxis at low-light intensities (10 W/m2). Phototaxis is based on blue light-activated adenylyl cyclases, which produce cAMP upon irradiation. In the absence of light the cells swim upward in the water column (negative gravitaxis). The r...
