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
pho-3	IVR. Linked to pan-1 (<1%). Right of leu-2 (8%). Left of mat(18%) and the T(NM152) right breakpoint (745). Structural gene for repressible acid phosphatase with phosphodiesterase activity (745). Codominant in heterozygous pho-3/pho-3+ duplications. Apparently a member of both phosphorus and nitrogen regulatory circuits. Not under control of the nit-2 locus (278b). Scored on low-phosphate medium by staining reaction with bis-nitrophenylphosphate (745).	IVR	B
