Locus	Cultural Requirements	Link Group	Type
cys-10	IVL. Left of acon-3 (1 to 6%), ace-4 (19 to 33%), and cut (28 to 37%) (578, PB). (721) Uses cysteine, cystathionine, homocysteine, or methionine, with a slight response to thiosulfate (469, 596, 721); however, E. Kafer (personal communication) found good growth on thiosulfate. Growth is better on casein hydrolysate than on methionine (D.D. Perkins, unpublished data). cys-10 chol-1double mutants grow better on methionine alone than on methionine plus choline (721). Lacks sulfite reductase, as do cys-2 and cys-4mutants (596). Formerly called met-4; see reference 721.	IVL	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
