nuc-2	IIR. Between the T(NM177) breakpoints; hence, right of aro-3. Left of preg(1 to 2%) and pe (4%). Probably allelic with pcon (0/854) (593, 671). (514) Unable to use RNA or DNA as a phosphorus source (514). Defective in production of repressible alkaline and acid phosphatases (671, 1077). Several nucleases absent or reduced (449). Interaction with other phosphate regulatory genes (665). Recessive to nuc+ in partial diploids and heterokaryons (671). Not defective in nuh function (538). Scored on low-phosphate medium by a staining reaction with alpha-naphthyl phosphate plus diazo blue B (397, 1077), by failure to grow on minimal medium altered so that 0.1 g of RNA or DNA per liter is substituted for the inorganic phosphate source (514, 538), or by failure to grow on low-phosphate medium at a pH above 7 (R.L. Metzenberg, personal communication). Used to study phosphate transport (624). For a regulation model, see references 665 and 670. See pcon.	IIR	B
