Locus	Cultural Requirements	Link Group	Type
ad-8	VIL. Right of ser-6 (15%) and het-8 (12%). Left of aro-6 (8%) and cpl-1(6 to 11%) (437, 510, 730, PB). Requires adenine; cannot use hypoxanthine (526). Lacks adenylosuccinate synthase (511) (Fig. 8). Fine-structure mapping and intralocus complementation (510-512). Has little hypoxanthine uptake and little hypoxanthine phosphoribosyltransferase; both these effects are partly counteracted in ad-1 ad-8 double mutants (903). Little hypoxanthine phosphoribosyltransferase is also found in mep(3) and mep(10)mutants, q.v. Used to study purine transport (787, 903, and references therein). Called complementation group E.	VIL	B
ylo-1	VIL. Between cys-1 (8%) and ad-1 (6%). Probably right of Bml (2%) (1012, PB). (381). Yellow carotenoids (381). Affects synthesis of neurosporaxanthin (4'-apo-beta'-caroten-4'-oic acid); citations in reference 398. Lesion probably involves the conversion of lycopene to 3,4-dehydrolycopene or the conversion of either torulene or gamma-carotene to neurosporaxanthin (398 and references therein) (Fig. 9). Resembles the orange wild type in young cultures, but color differences become clear with age. Expressed in both conidia and mycelia. Undefined modifiers affect intensity. Fails to complement with many of the al-1 and al-2 albino strains (R.E. Subden, personal communication).	VIL	B
