cultural_requirements: Nonsense suppressors (either proved or putative). In a few cases, putative missense mutations were also suppressed (749). Allele specific but not locus specific. Often infertile or only slightly fertile (ssu-3) when used as the female parent, forming no perithecia or empty perithecia (954). Strains of genotype ssu-1;am or ssu-2;am or ssu-3;am or ssu-4;am or ssu-5, but not ssu-6, are cold sensitive, showing less than half the wild-type growth rate at 10°C on minimal medium (894). Nucleus-restricted action has been studied in heterokaryons (409). Interaction of certain supersuppressors with certain ad-3B alleles produces erratic stop-start growth (408). For tabular summaries of action on differential test alleles, see references 145, 955, and 957.
