Two light-activated conductances in the eye of the green alga Volvox carteri.

Biophysical journal - 1 Mar 1999

Braun F J, Hegemann P

Abstract excerpt

Photoreceptor currents of the multicellular green alga Volvox carteri were analyzed using a dissolver mutant. The photocurrents are restricted to the eyespot region of somatic cells. Photocurrents are detectable from intact cells and excised eyes. The rhodopsin action spectrum suggests that the currents are induced by Volvox rhodopsin. Flash-induced photocurrents are a composition of a fast Ca2+-carried current...
