tyrosinase-1

locus: ty-1

locus_name: tyrosinase-1

organism_type: B

chromosome_number: III

chromosome_side: R

link_group: IIIR

cultural_requirements: IIIR. Linked to tyr-1 (0 to 6%) and dow (21%) (1115, PB). Tyrosinase repressed. Recessive (475, 477). Uninducible by protein synthesis inhibitors in the sexual phase but inducible in vegetative culture (472, 477). Prototrophic. Velvet-like vegetative morphology. Female infertile (no or few perithecia) but fertile as male. Infertility is recessive in heterokaryons (475). Low ascospore viability (459). Scored by color reaction with DL-3,4-dihydroxyphenylalanine as the substrate (475, 477) or by morphology and female sterility.
