Abstract
An assay of tyrosinase activity has been carried out inFusarium vasinfectum Atk. mutants differing in their pathogenicity. The results obtained reveal that the tyrosinase activity is more in the nicotinic acid requirer which is highly pathogenic than the other two strains. The non-pathogenic paraaminobenzoic acid requirer also possesses tyrosinase activity but comparatively less. In vitro studies were carried out by growing the pathogen in presence of host extracts. The susceptible host extract forms better source for the production of tyrosinase by the pathogen. Studies on tyrosinase activity of resistant and susceptible varieties of host inoculated with the parent strain ofF. vasinfectum in comparison with the respective uninoculated types suggest that a decline of tyrosinase activity occurs in all the hosts on inoculation.
