Abstract
Over 100 years ago, dramatic changes in the color phenotypes of certain filamentous cyanobacteria in response to changing ambient light conditions were first described. This acclimation process, known as complementary chromatic adaptation (CCA), leads to cell coloration that can range from brick red to blue-green. CCA is a photoreversible process with features that are similar to processes controlled by plant phytochrome photoreceptors. This review provides an overview of the physiology of CCA as well as a summary of recent findings concerning the nature and function of the signal transduction pathways used to regulate CCA in the filamentous cyanobacterium Fremyella diplosiphon, which has been used as a model system to study this process for over four decades. For historical perspeclives on CCA, the reader is referred to other reviews (Bogorad 1975, Tandeau de Marsac (2003).
