Genes

Locus	Cultural Requirements	Link Group	Type
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	B
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	B
nic-1	IR. Right of ace-3 (<1%), lys-1 (1%), and In(OY323). Left of os-1(10 to 29%) (2, 57, 131, 578, 789, 816, 907). (482) Uses nicotinic acid or nicotinamide, but not precursors (97, 100) (Fig. 18). Accumulates quinolinic acid (100). Used to study intralocus recombination (907). Called the q locus.	IR	B
