Regulation of cAMP-mediated Photosignaling by a Phytochrome in the Cyanobacterium Anabaena cylindrica
ABSTRACT Changes in cellular adenosine 3′,5′‐cyclic monophosphate (cAMP) content induced by monochromatic light of various wavelengths were determined in the cyanobacterium Anabaena cylindrica. Irradiation with monochromatic red light caused a rapid decrease in cAMP content. In contrast, far‐red lig...

Summary: | ABSTRACT
Changes in cellular adenosine 3′,5′‐cyclic monophosphate (cAMP) content induced by monochromatic light of various wavelengths were determined in the cyanobacterium Anabaena cylindrica. Irradiation with monochromatic red light caused a rapid decrease in cAMP content. In contrast, far‐red light caused a rapid increase in its content. The effects of red and far‐red light were reversible, suggesting the involvement of a prototype phytochrome as the photoreceptor for cAMP‐mediated light‐responsive signal transduction. |
