[[http://www.uniprot.org/uniprot/PHY1_SYNY3 PHY1_SYNY3]] Regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light: the R form that absorbs maximally in the red region of the spectrum and the FR form that absorbs maximally in the far-red region. Has also a slight blue shift for the far-red maximum. Forms a two-component system with the rcp1 response regulator.
