Locus	Cultural Requirements	Link Group	Type
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
cys-2	VIL. Between un-4 (4%) and cys-1 (1 to 3%). Very close to or contiguous with cys-1, but is probably a separate locus (721, 1012). (M. Fling, cited by T. H. Pittenger, Genetics 39:326-342, 1954) Uses cysteine or methionine. Strains carrying these alleles are heterogeneous in response to thiosulfate, but do not use sulfite (721). Lacks sulfite reductase, as do the cys-4 and cys-10 mutants (596). No interallelic complementation. Used in studies of intra- and interlocus recombination (see cys-1).	VIL	B
