Genes

Locus	Cultural Requirements	Link Group	Type
fs-1	I or II. Linked to T(I;II)4637. Unlinked to mt(732).Perithecia are absent or infrequent when used as the female (protoperithecial) parent. Fertile as the male. Some strains produce occasional perithecia and ascospores. Vegetative growth is somewhat stringy, slightly slower, and paler than that of the wild type. Recessive in heterokaryons. Complements fs-2, -3, 4, -5, -6, and -n. (732; O.M. Mylyk, personal communication). Shown nonallelic with fs-2, -3, -5, and -n in crosses (732).	I or II	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
