Locus	Cultural Requirements	Link Group	Type
fr	IL. Between ro-10 (18%) and un-5 (6%) (798, PB). (789)Delicate branching on agar surface and delicate aerial growth with no conidia (789). Multiple hyphal branching (382). Deficient in glucose- 6-phosphate dehydrogenase (as are col-2 and balmutants) (949, 952). Partially deficient in linolenic acid (115); morphology partially corrected by exogenous linolenic acid (892, 943). Low adenylate cyclase activity and low adenosine 3',5'-phosphate (943, 950). Used to determine what functions are controlled by adenosine 3',5'-phosphate (779). Unlike cr-1, fr is not corrected morphologically by exogenous cyclic nucleotides (892, 951). Scott (943) reported that morphology is corrected by theophylline; Rosenberg and Pall (892) reported no correction by phosphodiesterase inhibitors. Cell wall analysis; photograph (112, 278, 946). Reduced amount of cell wall peptides (1165). Recessive in duplications (808). Female sterile. Both known alleles (B110 and R2499) revert to fr+.	IL	B
scr	IIR. Linked to arg-12 (2%); probably to the left (PB). (828) Semicolonial growth, few aerial hyphae, dichotomization of hyphal tips, reduced conidiation. Heat sensitive, growing poorly with no conidia at 39 C and more like the wild type at 25°C. Asci abnormal in homozygous scrx scrcrosses, with altered arrangement of ascospores. Occasional asci have fewer than eight ascospores, and these include large spores. Not all asci are nonlinear. Recessive. (827, 828)	IIR	B
