Genes

Locus	Cultural Requirements	Link Group	Type
ad-9	IR. Right of met-6 (9 to 16%). Left of Tp(T54M94) and nit-1 (3 to 15%) (466, 816). (815) Uses adenine or hypoxanthine (526). Controls conversion of phosphoribosylglycineamide to phosphoribosylformylglycineamide (120) (Fig. 8). Called complementation group D.	IR	B
T(I->VI)NM103	Translocation		B
al-2	IR. Right of os-5 (<1%) and T(STL76). Left of arg-6(1%) and al-1 (797, 802, 808, 816, 818). Included in duplications from Tp(T54M94), confirming location left of arg-6(808). (482) Carotenoids absent or abnormal, but steroids produced (398). Blocked in microsomal fraction and defective in phytoene synthetase (445), a particulate enzyme (445 and references cited therein) (Fig. 9). Tracer experiments indicate a lesion between prephytoene pyrophosphate and phytoene (572). Alleles include those resulting in white and pale rose-white, e.g., 15300 and Y254MI65 (1042), and purple, e.g., MN58a (154). For complementation, see references 500 and 1041. Fine-structure mapping (500, 1042) needs reevaluation because of new information on the location of the arg-6 marker (797).	IR	B
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
