Genes

Locus	Cultural Requirements	Link Group	Type
leu-3	IL. Right of the In(OY323) left breakpoint and nit-2 (12 to 18%). Left of cyt-1 (5 to 8%) and T(OY321) (57, 816, PB; D.D. Perkins, N.B. Raju, and E.G. Barry, in preparation). (868)Requires leucine (867, 868). Regulatory mutation; prevents synthesis of alpha-isopropylmalate isomerase and beta-isopropylmalate dehydrogenase and prevents full derepression of alpha-isopropylmalate synthetase; also involved in regulation of isoleucine and valine synthesis, q.v. (427, 771, 833) (Fig. 15). The original allele, 47313, is leaky, but some other alleles, e.g., R156, are not.	IL	B
mus-9	IR. Between cyh-1 (18%) and al-2 (6%) (537). Sensitive to UV, X rays, methyl methane sulfonate, histidine, nitrosoguanidine, and mitomycin C. High spontaneous mutation; little or no mutability by UV or X rays. Homozygous sterile. Reduced conidial viability. (537, 539) Defective in extracellular nuclease, giving reduced halos around colony on DNA agar (537). Initially called uvs(FK104) in reference 538.	IR	B
