Abstract

Light signals have profound morphogenic effects on plant development. Signals perceived by the red/far-red absorbing phytochrome family of photoreceptors and the blue/green/ UV-A absorbing cryptochrome photoreceptor converge on a group of pleiotropic gene products defined by the COP/DET loci to control the pattern of development. The signaling pathway, although still undefined, includes several classic signaling molecules, such as G-proteins, calcium, calmodulin, and cGMP. A separate signaling pathway is involved in the modulation of the phototropic response. Additional mutants have been identified that affect subsets of light signaling responses. This review provides an overview of our current understanding of the light signaling process, in particular recent genetic and biochemical advances.
