| Abstract |
The Cryptochrome/Photolyase Family (CPF) represents an ancient group of widely distributed UV-A/blue-light sensitive proteins sharing common structures and chromophores. During the course of evolution, different CPFs acquired distinct functions in DNA repair, light perception and circadian clock regulation. Previous phylogenetic analyses of the CPF have allowed reconstruction of the evolution and distribution of the different CPF super-classes in the tree of life. However, so far only limited information is available from the CPF orthologs in aquatic organisms that evolved in environments harboring great diversity of life forms and showing peculiar light distribution and rhythms. To gain new insights into the evolutionary and functional relationships within the CPF family, we performed a detailed study of CPF members from marine (diatoms, sea urchin and annelid) and freshwater organisms (teleost) that populate diverse habitats and exhibit different life strategies. In particular, we first extended the CPF family phylogeny by including genes from aquatic organisms representative of several branches of the tree of life. Our analysis identifies four major super-classes of CPF proteins and importantly singles out the presence of a plant-like CRY in diatoms and in metazoans. Moreover, we show a dynamic evolution of Cpf genes in eukaryotes with various events of gene duplication coupled to functional diversification and gene loss, which have shaped the complex array of Cpf genes in extant aquatic organisms. Second, we uncover clear rhythmic diurnal expression patterns and light-dependent regulation for the majority of the analyzed Cpf genes in our reference species.Our analyses reconstruct the molecular evolution of the CPF family in eukaryotes and provide a solid foundation for a systematic characterization of novel light activated proteins in aquatic environments. |
