Genes

Locus	Cultural Requirements	Link Group	Type
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
ro-3	IIL. Right of pyr-4 (1 to 2%). Left of T(NM149) and thr-2 (6 to 25%) (808, 812). Resembles ro-1 (812). Growth limited on glycerol medium (212). Called cflon map in reference 812.	IIL	B
