摘要：

The 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, have been found to be utilized by phytochrome to control the expression of genes required for chloroplast development (e.g., CAB and FNR) and anthocyanin biosynthesis (e.g., CHS). In particular, cGMP is a second messenger positively regulating CHS gene expression whilst calcium and calmodulin act as negative regulators. In addition to phytochrome regulation of CHS we have begun to examine the signal transduction pathways utilized by UV photoreceptors. In contrast to phytochrome-mediated responses, results indicate a role for calcium and calmodulin as positive regulators of CHS gene expression in UV light.
