Phycomyces wc genes and proteins. (A) Genomic structure of Phycomyces wc genes including flanking genes with their putative identities. Exons, introns, and direction of transcription are indicated. (B) WC proteins in the Phycomyces genome and their domains. (C) Phylogenies of the WC proteins. Phylogenetic trees of the LOV domains from fungal WC-1 proteins and photoreceptor proteins from plants and bacteria, and from WC-2 proteins (for accession numbers see SI Text). Bars represent the number of substitutions per site. The wctA gene and the WCTA protein are indicated as madB and MADB, respectively.
