Genes

Locus	Cultural Requirements	Link Group	Type
cum	IIIL. Left of r(Sk-2) (4%), acr-7 (5 to 18%), and acr-2(18%). No recombination with Sk-2K. (PB; B.C. Turner, personal communication) Initially colonial; then spreads and sends up blooms of aerial hyphae which conidiate profusely at the shallow ends of agar slants. Good female fertility. Similar in morphology to the mutants sn and sp and to the mutant cot-4 at 25 C (PB).	IIIL	B
r(Sk-2)-1	IIIL. Left of acr-7 (7%) and sc (17%) (1092; B.C. Turner, personal communication). Allelism of r(Sk-2)-1 with Sk-2 is not excluded because Sk-2K blocks recombination in this region. r(Sk-2)-1 itself does not block recombination. Prevents killing of ascospores by Sk-2K - Not resistant to killing by Sk-3K. Allele P527 found in N. crassa from Louisiana. Only one other known N. crassa wild type is resistant. (B.C. Turner, personal communication)	IIIL	B
acr-7	IIIL. Left of sc (12 to 14%). Linked to thi-4 (7%) (PB). Right of r(Sk-2)-1 (7%) (B.C. Turner, personal communication). Report of VI linkage in reference 818, is incorrect.Resistant to acriflavine (50 µg /ml). Not cross-resistant to 3-aminotriazole or malachite green. Several acr-7 strains have become female infertile after vegetative transfer. (PB)	IIIL	B
