Genes

Locus	Cultural Requirements	Link Group	Type
fs-4	I? Linked mating type (22%) (732). May be inseparable from a chromosome rearrangement (O.M. Mylyk, personal communication).No perithecia when used as the female. Fertile as the male. Complements fs-1, -2, -3, -5, -6, and -n. Vegetative growth is slightly slower and paler than that of the wild type. Recessive in heterokaryons. (732; O.M. Mylyk, personal communication)	I?	B
nic-3	VIIL. Right of spco-4 (1%) and do (3%). Left of thi-3 (9 to 27%) and csp-2 (16 to 22%) (539, 812, 816, PB). (M.K. Allen, cited in references 718 and 789) Uses nicotinic acid, nicotinamide, 3-hydroxyanthranilic acid, 3-hydroxykynurenine, or high concentrations of quinolinic acid (96, 1168). Accumulates alpha-N-acetylkynurenine; blocked in conversion of kynurenine to 3-hydroxykynurenine (1168) (Fig. 18). Pyridine nucleotide levels (111). Pathway from tryptophan to nicotinic mononucleotide, showing sites of gene action (96, 100, 368, 1168). The enzymatic reactions between 3-hydroxyanthranilate and nicotinic mononucleotide have not been demonstrated directly in Neurospora.	VIIL	B
