Bipolaris oryzae is a filamentous ascomycetous fungus that causes brown leaf spot disease in rice. We isolated and characterized BLR2, a gene that encodes a putative blue-light regulator similar to Neurospora crassa white collar-2 (WC-2). The deduced amino acid sequence of the BLR2 showed significant homology to other fungal blue-light regulator proteins in the Per-Arnt-Sim (PAS) protein-protein interaction domain, nuclear localization signal, and GATA zinc finger DNA-binding domains. The BLR2-silenced transformants hardly produced conidia in the subsequent dark condition after near-ultraviolet (NUV) irradiation. Furthermore, the BLR2-silenced transformants suppressed the photolyase (PHR1) gene expression enhanced by NUV irradiation. These results indicate that BLR2 is necessary not only for conidial formation, but also for NUV radiation-enhanced photolyase gene expression in B. oryzae.
