Another interesting study suggesting that giant viruses can control phototaxis in their hosts during infection

"... we show here that light irradiation reversibly modified tail movements of OLPVR1-expressing frog tadpoles."
Hijacking of internal calcium dynamics by intracellularly residing viral rhodopsins - Nature Communications
Rhodopsins are ubiquitous light-driven membrane proteins that have diverse functions in nature, and value as optogenetics tools. Here the authors characterise type 1 viral channelrhodopsins, showing that they regulate intracellular calcium and can be used for the photocontrol of muscle contraction in vivo.
