Locus	Cultural Requirements	Link Group	Type
lys-5	VIL. Right of cyt-2 (6%), aro-6 (3%), and cpl-1 (5 to 7%). Left of un-4 (2%) (1012, PB).Requires lysine. Partial response to glutaric acid (762). Lacks homocitrate synthase activity (464, 762) (Fig. 16). Some alleles such as 37402, called asco, are autonomous ascospore lethals or semilethals, resulting in mostly immature white spores (see reference 1012 for a photograph). Viability of the lys- spores is improved by long incubation (7). With other alleles such as DS6-85, ascospores blacken and germinate normally. Accumulates malate plus citrate on media with limiting lysine concentrations (464). Four complementation groups (12). Allele 37402 called asco.	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
