The function of NPL1 and what role, if any, it plays in Arabidopsis blue light responses, remains to be determined. The role of mutants in the search for the photoreceptor for phototropism in higher plants. Plant Cell Environ. Dependence of the phototropic response of Arabidopsis thaliana on fluence rate and wavelength. Mutations in the NPH1 locus of Arabidopsis disrupt the perception of phototropic stimuli.
Blue light activates a specific protein kinase in higher plants.
Exposure of oat seedlings to blue light results in amplified phosphorylation of the putative photoreceptor for phototropism and higher sensitivity of the plants to phototropic stimulation. PAS domains S-boxes in archae, bacteria and sensors for oxygen and redox.
