title: Genomewide analysis of phytochrome proteins in the phylum Basidiomycota.
abstract: Phytochromes are photoreceptor proteins involved in the detection of the red and far-red regions of the visible light spectrum. Fungal phytochromes are hybrid histidine kinases with a conserved domain architecture composed of an N-terminal photosensory module and a C-terminal regulatory output module that includes the histidine kinase and response regulator receiver domains. In this study, we have analyzed the distribution, domain architecture, and phylogenetic analysis of phytochrome proteins in 47 published genome sequences among the phylum Basidiomycota. Genome analysis revealed that almost every genome of basidiomycetes contained at least one gene encoding a phytochrome protein. Domain architecture of fungal phytochromes was completely conserved in the identified phytochromes of basidiomycetes, and phylogenetic analysis clustered these proteins into clades related with the phylogenetic classification of this fungal phylum.
