Abstract
Phytochrome exerts many of its effects on plant morphogenesis by changing patterns of gene expression (Nagy et al., 1988). Although the transcription of many genes has been shown to be under phytochrome control, little is known about the chain of events that transmits the light signal to the genome. One valid approach towards unravelling the signal transduction pathway is to identify the cis-acting DNA sequences that mediate the phytochrome response and the protein factors that specifically interact with them. An understanding of the regulation of these factors provides an entry point from which one can eventually work ‘backwards’ towards the photoreceptor, bearing in mind that multiple and redundant light switches may exist for any one gene (Gilmartin et al., 1990).
