緑藻クラミドモナスは眼点によって光源方向を認識して走光性を示す。細胞膜上の光受容体を、光反射板の役割をする色素層が裏打ちすることで、眼点は高指向性光受容を行う。我々は野生株と逆方向に泳ぐ変異株を単離し、その原因が色素層の欠損であることを見出した。逆方向に泳ぐのは、色素層を失った眼点が、細胞を通ってレンズ効果によって集光された光のほうが、正面から来る光よりも強いと感じ、光源方向を誤認するからだと考えた。しかし査読者はクラミドモナスが凸レンズになるわけがないと言う。我々は顕微鏡光路にPの字（photoの頭文字）を置き、細胞上にPの字が見えれば反論できると考えた。結果はご覧の通り (Ueki, Ide et al., 2016 PNAS)。 撮影装置名（メーカーとモデル）： 顕微鏡 オリンパス BX-53、カメラ オムロンセンテック STC-MCA5MUSB3
