(A) Faminzin, pioneer of algal behavior (4). (B) Faminzin’s landmark observation (5): At low light intensities (bottom), Chlamydomonas exhibits phototaxis toward light, whereas at higher light intensities (top) the algal cells accumulate at optimal irradiance. (C) Adapted cartoons showing subcellular Chlamydomonas structure: flagellar beating pattern (20) and eye structure reconstructed from high-resolution tomography (17). Eyespot overlaying part of plasma membrane (arrow) corresponds to ChR location. Layers of carotenoid-containing vesicles (colored spheres) held by chloroplast membranes (green) serve as an optical device (interference reflector) (4, 19).
