Locus	Cultural Requirements	Link Group	Type
csp-2	VIIL. Linked to thi-3 (<1%), probably to the right. Left of T(T54M40) (972, PB). Conidia fail to separate and become airborne. Cultures on agar readily scored by the tap test. Resembles csp-1. Conidia are freed in water suspension long after induction of aerial growth and at only 1/100 the concentration of the wild type. A csp-1;csp-2double mutant releases no detectable free conidia under the same conditions (972). Most csp-2alleles complement csp-1 in forced heterokaryons to form the wild-type number of free conidia (972), but csp-2(UCLA102) does not (969). Conidiating colonies of the csp-2;sn cr-1 strain on replica plates can be overlayered without the conidia being spread (744); photograph (747).	VIIL	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
