Disruption of the cyanide hydratase gene in Gloeocercospora sorghi increases its sensitivity to the phytoanticipin cyanide but does not affect its pathogenicity on the cyanogenic plant sorghum



Disruption of the cyanide hydratase gene in Gloeocercospora sorghi increases its sensitivity to the phytoanticipin cyanide but does not affect its pathogenicity on the cyanogenic plant sorghum



Fungal Genetics and Biology 28(2): 126-134



The cyanide hydratase gene was used to make a mutant of G. sorghi and the virulence of this mutant on a cyanogenic variety of sorghum was determined. The mutant was highly sensitive to hydrogen cyanide and it is concluded that cyanide hydratase is responsible for detoxifying hydrogen cyanide. However, the mutant was virulent to sorghum and caused lesions which were identical to those of the wild-type strain.
