Photosensory perception and signal transduction in plants

Curr Opin Genet Dev. 1994 Oct;4(5):652-61. doi: 10.1016/0959-437x(94)90131-l.


Genetic and molecular studies are beginning to unravel the complexities of the signaling circuitry that plants use to sense and transduce information concerning the prevailing light environment. The past year has witnessed definition of discrete photosensory roles for phytochromes A and B, the cloning of a gene encoding the first apparent blue-light photoreceptor from any organism, the cloning of genes encoding additional members of the COP/DET/FUS class of light-responsive master regulators, and evidence that G proteins, Ca2+/calmodulin, and cGMP may be signaling intermediates in phototransduction.
