Identification of two photoreceptor genes, Fawc1 and Fawc2, in F. asiaticum. (A). Schematic demonstration of the domains of WC1 and WC2 orthologs from N. crassa, F. graminearum, and F. asiaticum. Accessions of the amino acid sequences are as follows: WC1 (NCU02356); WC2 (NCU00902); FgWC1 (FGSG_07941); FgWC2 (FGSG_00710); FaWC1 (KX905081.1); FaWC2 (MT019868). Domains of these photoreceptor proteins were analyzed via the SMART online tool (http://smart.embl-heidelberg.de/). PAS: Per-period circadian protein; Arnt: Ah receptor nuclear translocator protein; Sim: Single-minded protein, NLS: Nuclear Location Singal, Zn: Zinc finger binding to DNA consensus sequence. (B). Transcript levels of Fawc1 and Fawc2 are regulated by light. The horizontal axis indicates light treatment time. The bars present mean values ± SD of three replicate samples.
