Genes

Locus	Cultural Requirements	Link Group
inv	VR. Right of pab-2 (3%) and ro-4 (5 to 8%), Left of asn (4 to 9%) (918, PB).Unable to use sucrose as a carbon source. Grows well on glucose or fructose and fairly well on Casamino Acids or yeast extract. Invertase structural gene; invertase deficient and uninducible by normal inducers. Makes cross-reacting material (919). Invertase is also affected by cot-2, q.v.	VR
pab-1	VR. Between inl (1 to 10%) and met-3 (1 to 2%) (3629 1036). (47) Requires p-aminobenzoic acid (1057) (Fig. 11). Apparently cannot use folate (mono- or triglutamate) (1179).	VR
mcm	IIL. Linked to ro-7 (1%). When macroconidia from agar-grown mycelial cultures are germinated in liquid shake culture at 22°C, the germlings produce uninucleate microconidia within 24 hr, reaching concentrations of 10^7/ml at 72 hr. At 30°C, multinucleate arthroconidia and few or no micrconidia are produced. The morphology of surface-grown cultures is normal wild type.	IIL
