Light Signal Transduction Networks in Maize
2009Light signal transduction networks integrate environmental signals with endogenous developmental programs. Several photoreceptors, including phytochromes, cryptochromes, and phototropins as well as some of their signaling partners have been characterized in higher plants.

SPA1, a component of phytochrome A signal transduction, regulates the light signaling current
Planta, 2002Mutations in a component of phytochrome A (phyA)-specific light signal transduction, SPA1, result in enhanced responsiveness of Arabidopsis seedlings to red and far-red light. Here, we have examined the effects of spa1 mutations on the two known modes of phyA function, the high-irradiance responses (HIRs) to continuous irradiation with far-red light ...

Fresh view of light signal transduction in plants
Cell, 1994Through photosynthesis, light provides the energy source for plants and, ultimately, for all living organisms. In response to a fluctuating environment, the nonmotile plant must be able to sense varying light signals and to optimize growth and development.

Light Signal Transduction and Gene Expression
1999Light is one of the most important regulators of plant growth and development. Genetic, biochemical and physiological studies in plants have shown the existence of multiple photoreceptors for red, far-red, blue and UV light. The fact that a large number of photoresponses are regulated by various photoreceptors indicates the presence of different ...

Light Signal Transduction Mediated by Phytochromes
1996Light signal transduction in plants is mediated by the concerted interaction of UV-B, blue/UV-A, and red-light photoreceptors. The physiological effects of the activation of these photoreceptors are dramatically illustrated by comparing the morphologies of dark grown seedlings to those exposed to ambient light (Fig. 1). Dark-grown (etiolated) seedlings

Signal transduction in response to excess light: getting out of the chloroplast
Current Opinion in Plant Biology, 2002Plants are continually in danger of absorbing more light energy than they can use productively for their metabolism. Acclimation to environmental conditions therefore includes the development of mechanisms for dissipating or avoiding the accumulation of such excess excitation energy.

Transduction of light into a neural signal in photoreceptors
Physica Scripta, 1989The electrical response of a retinal photoreceptor to illumination involves the closure of ion-selective channels in the cell's plasma membrane. Analysis of the response kinetics suggests the involvement of a chain of linked reactions and recent biochemical experiments have indicated the probable molecular nature of these reactions.

The Transduction of Light Signals in Plants: Responses to Blue Light
1991Although the majority of articles in this volume are devoted to studies of phytochrome, there has been considerable progress recently in understanding plant responses to blue light — mediated not by the blue light-absorbing bands of phytochrome, but rather by specific blue light photoreceptors. These inroads are being made at the cellular, biochemical,

The transduction of light signals by phytochrome
1997Extraordinary progress has recently been made towards the understanding of how the plant photoreceptor phytochrome is able to transduce light signals into biological responses. This has been achieved by a combination of complementary genetic, biochemical, and cell biological approaches. We can now assign individual phytochromes to particular responses,
