PhyA is the photoreceptor of far-red light perception in Arabidopsis and mediates the inhibition of the hypocotyl elongation under FR light. phyA has two domains : the N-terminal photosensory domain with a chromophore-binding site and the C-terminal domain which contains signaling motifs such as a kinase domain.

phyA为阿拉伯芥中远红光的接受体，在远红光中可抑制下胚轴延长，phyA的N端带有一个可感受光讯息的色基，C端含有可传递讯息给下游基因的kinase区域。
