Genes

Locus	Cultural Requirements	Link Group	Type
cyh-1	IR. Right of nit-1 (6%). Left of T(STL76) and al-2 (8 to 13%) (496, 797, 808).Resistant to cycloheximide (496, 748). Resistance is recessive in duplications (1090). Dominance reported in forced heterokaryons (496, 748) may have been due to skewed nuclear ratios (1090). Protein synthesis on ribosomes of the mutant cyh-1 proceeds in the presence of cycloheximide in a cell-free system (834). Readily scored on slants with 10 µg of cycloheximide per ml autoclaved in the medium. Excellent as a marker and valuable for selecting somatic recombinants or deletions in heterozygous duplications (748, 1091). Used to show that the cycloheximide-induced phase shift of the circadian clock involves protein synthesis (738). Called act-1: actidione resistant-1.	IR	B
pan-2	VIR. Right of rib-1 (<1 to 3%). Left of del (6%) and trp-2(11%) (140, 141, 143, 818, PB). Unable to convert ketovaline to ketopantoic acid (138, 140, 141). Used in major studies of intralocus recombination and complementation (140-143). pan-2ascospores remain white or pale if the crossing medium is not supplemented, even when the protoperithecial parent is pan-2+. Asci in which gene conversion has occurred at pan-2 can thus be recognized and isolated (1072, 1073); photographs (1072). For good recovery of pan-2progeny, crossing media should be supplemented with pantothenic acid (10 µg/ml) even when the protoperithecial parent is pan+. Called group B.	VIR	B
