Genes

Locus	Cultural Requirements	Link Group	Type
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
arg-13	Responds well to arginine or citrulline and poorly to ornithine.	IR	B
nic-1	IR. Right of ace-3 (<1%), lys-1 (1%), and In(OY323). Left of os-1(10 to 29%) (2, 57, 131, 578, 789, 816, 907). (482) Uses nicotinic acid or nicotinamide, but not precursors (97, 100) (Fig. 18). Accumulates quinolinic acid (100). Used to study intralocus recombination (907). Called the q locus.	IR	B
un-18	IR. Right of T(NM169d) and R (11%) (808). Unknown function. Heat sensitive (507). No growth at 34°C. Growth at 25 C is substantial but not wild type, and better on complete medium than on minimal medium. Allele T54M94 is called 41 in reference 507.	IR	B
