Genes

Locus	Cultural Requirements	Link Group	Type
cys-1	VIL. Between cys-2 (1 to 3%) and ylo-1 (8%) (721,1012). (980) Uses sulfite, thiosulfate, cysteine, or methionine. Original isolate (allele 84605) also had a partial requirement for tyrosine and showed high tyrosinase activity at 25°C but not 35°C (479, 721, 980). These properties reverted, however, whereas the cysteine requirement is stable (479). Used in studies of intra- and interlocus recombination (721, 1015, 1016, 1024-1026).	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
