Genes

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
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
