Abstract

The signal transduction processes involved in the regulation of SAMDC gene expression by blue and red light were examined using pharmacological inhibitors of signalling pathways. Calcium and calmodulin positively regulated SAMDC gene expression in red light, whereas in blue light they regulated negatively. These results indicate that calcium homeostasis is involved in both red and blue light induction of SAMDC expression. Both signal transduction pathways also require new protein synthesis.

Key words: Blue-light receptor, Pharbitis nil, phytochrome, S-adenosylmethionine decarboxylase, signal transduction.
