光敏素，是植物体内的一种蛋白。（光敏素+发色团=>光敏色素）有钝化型和活化型两种形式，分别吸收红光和远红光而相互转化。植物主要通过这种色素接收外界的光信号来调节本身的生长和发育。
In higher plants, there are at least three kinds of light receptors to capture light signal: phytochrome, cryptochromes and phototropin, which receptor absorb different spectrum of light.
在高等植物体内,至少存在三种光受体捕捉光信号:光敏素,蓝光/UV-A受体和UV-B受体,每一种光受体吸收不同光谱的光。
