Bipolaris oryzae is a filamentous ascomycetous fungus that causes brown leaf spot disease in rice. We isolated and characterized BLR1 , a gene that encodes a putative blue‐light regulator similar to Neurospora crassa white‐collar 1 (WC‐1). The deduced amino acid sequence of BLR1 showed high degrees of similarity to other fungal blue‐light regulator protein. Disruption of the BLR1 gene demonstrated that this gene is essential for conidial development after conidiophore formation and for near‐UV radiation‐enhanced photolyase gene expression.
