Light signal transduction in plants

Abstract

Light 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. This review focuses upon recent approaches towards establishing the intermediates that transmit signals from photoreceptors, phytochromes in particular, to target elements in the promoters of light-regulated genes.
