Genes

Locus	Cultural Requirements	Link Group	Type
csp-1	IL. Between arg-3 (1%) and the T(39311) right breakpoint (972, PB). Conidia fail to separate and become airborne. Photograph (972). Recessive. Cultures on agar readily scored by the "tap test." In water, conidia are freed at 1/10 the wild-type concentration (972). Used in connection with bd for study of circadian rhythms (e.g., reference 114). Useful in student laboratories to avoid contamination (966). Carotenoids tend to be yellowish in young cultures (PB).	IL	B
nic-2	IR. Between ad-3B (4%) and ace-7 (4 to 7%) (271, 578). (482) Grows on nicotinic acid, nicotinamide, or high concentrations of quinolinic acid (97, 1168). Cannot use kynurenine, hydroxykynurenine, or hydroxyanthranilic acid (96, 1168). Accumulates 3-hydroxyanthranilic acid (96) (Fig. 18). Aging cultures accumulate red-brown pigment in the medium. Used to study intralocus recombination (908). Translocations T(4540) and T(S1325)are inseparable from nic-2 (808, 908, 911).	IR	B
