Arabidopsis thaliana possesses five different photoreceptors for red and far-red light, at least two different classes of proteins that serve as receptors for blue light and a poorly understood ...

When exposed to blue wavelengths of light, the melanopsin and G protein–coupled receptor kinase 2 (GRK2) mediate the relaxation of the vessels. The combination of light and a GRK2 inhibitor resulted ...
