Abstract

Hyphal morphology resembling that of branching runner hyphae (= macrohyphae) produced by Gaeumannomyces graminis on its wheat host were observed when the pathogen was grown on a cellulose membrane placed on potato-dextrose agar. The frequently branching hyphae exhibited multiple calcoflour white stain foci and higher chitin content, indicative of elevated chitin synthesis. A chitin synthase gene fragment (designated chsA) was amplified from G. graminis genomic DNA. chsA is a single copy gene and the predicted amino acid sequence of the isolated fragment is very similar to class I chitin synthases isolated from other filamentous fungi.
