About 250 by ura5 gene (Orotate phosphoribosyl transferase) fragment was cloned from genomic DNA of entomopathogenic fungus Metarhizium anisopliae by using PCR method. Entire nucleotide sequences of cloned DNA fragment were determined and analyzed as compared with other fungus ura5 genes. The amino acid sequence deduced from the nucleotide sequence showed 85.5% homology to ura5 protein of Trichoderma reesei. Using this 250 bp PCR fragment we have isolated full ura5 gene of M. anisopliae by genomic Southern hybridization and the isolated 4.4 kb DNA fragments were mapped by restrictional enzyme.
