Abstract: | Phytochromes were long thought to have evolved in non-motile photosynthetic eukaryotes for adaptation to unfavorable light environments, but recent studies suggest that phytochromes evolved billions of years earlier from a tetrapyrrole sensor protein progenitor. These investigations have identified phytochromes and phytochrome-related proteins in photosynthetic bacteria (cyanobacteria and purple bacteria), nonphotosynthetic eubacteria and fungi - an observation that has opened new avenues for investigating the origins, molecular evolution and biochemical functions of this ecologically important family of plant photoreceptors. |
