Genes

Locus	Cultural Requirements	Link Group	Type
his-2	IR. Right of T(AR190) and un-2 (<1%). Left of the T(AR173) right breakpoint and of nuc-1 (<1%) (172, 670, 808). (434)Requires histidine (434). Affects adenosine 5'-triphosphate phosphoribosylpyrophosphate pyrophosphorylase (16) (Fig. 14). Intralocus complementation (162). Recombination between his-2 alleles is controlled by rec-3(173); it is not affected by rec-1 (172). Initial his-2 allele called C94.	IR	B
pdx-1	IVR. Right of pyr-1 (<1 to 10%). Left of T(S1229) and pt (2%) (40, 55, 692, 808). (482) Uses pyridoxine, pyridoxal, or pyridoxamine (843, 845, 846). Shows intralocus complementation (845, 846) and recombination (848), Provided the first proven example of gene conversion (686). Scoring is sharpened by addition of 100 mg of desoxypyridoxine per liter (845). Several alleles (called pdxp: e.g., 44602) are pH sensitive and can grow without pyridoxine on medium containing ammonium ions at a pH above 6 (1029). Conidia are subject to death by unbalanced growth on minimal medium (1033). A yellow pigment is excreted under certain conditions by the pdx-1;En(pdx) double mutant; see En(pdx). Allele 44204 originally called pdx-2 (see reference 848).	IVR	B
mtr(t-8)	Resistant to 4-methyltryptophan and p-fluorophenylalanine.	IVR	B
