Bialaphos resistance as a dominant selectable marker in Neurospora crassa.

Author information

Department of Genetics, University of Georgia, Athens 30602.


Conidia of Neurospora crassa are sensitive to the herbicide bialaphos at concentrations of 160 mg/l in Westergaard's or Fries' minimal media. Plasmid pJA4 was constructed by inserting a truncated bar gene from Streptomyces hygroscopicus fused to the his-3 promoter from N. crassa into pUC19. The bar gene in plasmid pJA4 confers resistance to bialaphos when transformants are selected on a medium containing bialaphos. The bar gene can be used as an additional dominant selectable marker for transformation of fungi.
