Genes

Locus	Cultural Requirements	Link Group	Type
ad-1	VIL. Right of ylo-1 (6%). Left of the centromere (< 1 to 2%), T(AR209), and rib-1(3 to 5%) (1102, 1012). (482) Uses adenine or hypoxanthine (682, 824). Accumulates AICAR (81, 904) and SAICAR (81). May affect inosine 5'-monophosphate cyclohydrolase (902, 904) (Fig. 8). Used to study purine transport (903 and references therein). Ascospores are white in homozygous ad-1 x ad-1 crosses, and ad-1 ascospores may be white in heterozygous crosses (D.D. Perkins, unpublished data). Called complementation group M.	VIL	B
pan-2	VIR. Right of rib-1 (<1 to 3%). Left of del (6%) and trp-2(11%) (140, 141, 143, 818, PB). Unable to convert ketovaline to ketopantoic acid (138, 140, 141). Used in major studies of intralocus recombination and complementation (140-143). pan-2ascospores remain white or pale if the crossing medium is not supplemented, even when the protoperithecial parent is pan-2+. Asci in which gene conversion has occurred at pan-2 can thus be recognized and isolated (1072, 1073); photographs (1072). For good recovery of pan-2progeny, crossing media should be supplemented with pantothenic acid (10 µg/ml) even when the protoperithecial parent is pan+. Called group B.	VIR	B
