Genes

Locus	Cultural Requirements	Link Group	Type
cys-10	IVL. Left of acon-3 (1 to 6%), ace-4 (19 to 33%), and cut (28 to 37%) (578, PB). (721) Uses cysteine, cystathionine, homocysteine, or methionine, with a slight response to thiosulfate (469, 596, 721); however, E. Kafer (personal communication) found good growth on thiosulfate. Growth is better on casein hydrolysate than on methionine (D.D. Perkins, unpublished data). cys-10 chol-1double mutants grow better on methionine alone than on methionine plus choline (721). Lacks sulfite reductase, as do cys-2 and cys-4mutants (596). Formerly called met-4; see reference 721.	IVL	B
col-4	IVR. Between met-1 (4%) and arg-2 (<1 to 2%) (692, 876, 991). (695) Spreading colonial morphology, forming dense balls of conidia high in slants (47). Probably dominant in heterozygous duplications from T(S1229) (E.G. Barry, personal communication). Cell wall-autolyzing enzyme (631). Reduced amount of cell wall peptides (1165). Used in combination with pe fl to produce microconidiating colonial growth suitable for reversion experiments (386). Called spco-1 (382); called c (386).	IVR	B
