In this study, we have researched the mechanism of complementary chromatic adaptation in marine red algae Porphyra yezoensis. Some visually dramatic changes in pigmentation of P. yezoensis gametophytes that occur during changing light conditions were reversibly. Therefore it was suggested that P. yezoensis gametophytes have complementary chromatic adaptation ability. Moreover, it was thought that the system was regulated by the light responsiveness of genes that encode several light-harvesting proteins in P. yezoensis.

本研究对条斑紫菜的互补色适应机制进行了研究。条斑紫菜配子体在光照条件变化过程中发生的一些视觉上显著的色素变化是可逆的。因此，条斑紫菜配子体具有互补的色适应能力。此外，人们认为该系统是由编码条斑紫菜中几种捕光蛋白的基因的光响应性调节的。
