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 ...

ERK signaling dynamics: Lights, camera, transduction
Developmental Cell, 2022Three-dimensional mammary epithelial acini are a model for understanding how microenvironment-driven signaling coordinates cell behavior and tissue morphogenesis. In this issue of Developmental Cell, Ender et al. use live-cell imaging to capture dynamic spatiotemporal patterns of ERK activity that instruct cell migration and survival fates in ...

Light signal transduction in plants
Trends in Cell Biology, 1997Light signal-transduction pathways are a central component of the mechanisms that regulate plant development. These pathways provide the means by which information from specific wavelengths of light may be amplified and coordinated, resulting in complex physiological and developmental responses.

Light Signal Transduction in Plants
Photochemistry and Photobiology, 1996Plants, as sessile organisms, have developed intricate signal transduction networks used to adapt to the changing environment surrounding them. One of the most important dynamic environmental factors is light, and the light control of dicotyledonous seedling development is one of the best studied examples.

Ion channels and the transduction of light signals
Plant, Cell & Environment, 2000ABSTRACTStudies of biological light‐sensing mechanisms are revealing important roles for ion channels. Photosensory transduction in plants is no exception. In this article, the evidence that ion channels perform such signal‐transducing functions in the complex array of mechanisms that bring about plant photomorphogenesis will be reviewed and discussed.

Transduction of Light Signals in Plants
1996The phytochromes are the best studied plant photoreceptors, controlling a wide variety of responses at both whole plant and single cell levels. Three signal transduction pathways, dependent on cGMP and/or calcium, are used by phytochrome to control the expression of genes required for chloroplast development and anthocyanin biosynthesis. Control of the

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

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.

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 ...
