Abstract
To grow and develop optimally, all organisms need to perceive and proc ess information from both their biotic and abiotic surroundings. A par ticularly important environmental cue is light, to which organisms res pond in many different ways. Because they are photosynthetic and non-m otile, plants need to be especially plastic in response to their light environment. The diverse responses of plants to light require sophist icated sensing of its intensity, direction, duration, and wavelength. The action spectra of light responses provided assays to identify thre e photoreceptor systems absorbing in the red/far-red, blue/near-ultrav iolet, and ultraviolet spectral ranges. Following absorption of light, photoreceptors interact with other signal transduction elements, whic h eventually leads to many molecular and morphological responses. Whil e a complete signal transduction cascade is not known yet, molecular g enetic studies using the model plant Arabidopsis have led to substanti al progress in dissecting the signal transduction network. Important g ains have been made in determining the function of the photoreceptors, the terminal response pathways, and the intervening signal transducti on components.
