Genes

Locus	Cultural Requirements	Link Group	Type
cys-14	IV. Linked to cot-1 (21%) (640). Deficient sulfate transport in the mycelial stage, but sensitive to chromate. Lacks sulfur permease II (mycelial type) (639, 640). Double mutant cys-14;cys-13 cannot transport inorganic sulfate, grows on methionine; both single mutants are prototrophic (640).	IV	B
cys-13	IR. Right of his-3 (2%) (640). Resistant to chromate; no demonstrable requirement. Deficient in sulfur permease I (conidial type) (639, 640). Score on minimal agar with 25 mM chromate and 0.25 mM methionine after 3 days or longer, 34°C. (Strains carrying regulatory gene cys-3 are also chromate resistant.)	IR	B
