Strains carrying this gene

Strain Genotype Description
BA824 spe-26(hc139) dpy-20(e1282) IV. Temperature sensitive. Partially fertile at 16C (very few progeny). Sterile at 20C and 25C. Weak Dpy at 15C. Spermatogenesis arrests at the spermatocyte stage.
BA825 spe-26(hc140) dpy-20(e1282)/+ IV. Heterozygotes are WT and segregate wild-type, wild-type heterozygotes, and Sterile Dpy (spe-4 dpy-20 homozygotes). Homozygous mutants are weak Dpy and partially fertile at 15C. Sterile at 20-25C. Spermatogenesis arrests at the spermatocyte stage.
BA901 spe-27(it110) dpy-20(e1282) IV. Temperature sensitive Dpy. Male/hermaphrodite mating strain. Hermaphrodites self-sterile at all temps; males fertile. Spermatids arrest with spikes in pronase; form normal pseudopods in TEA.
BA925 spe-26(hc138) dpy-20(e1282) IV. Temperature-sensitive. Fertile and weak Dpy at 15C. Partially fertile at 20C. Sterile at 25C. Twitcher. Spermatogenesis arrests at the spermatocyte stage.
BA959 spe-29(it127) dpy-20(e1282) IV. Homozygous male/hermaphrodite line. Males are fertile. Hermaphrodites are sterile, but slightly leaky producing a few progeny (at 25C - ts not tested). In pronase, spermatids from males activate to form many long spikes, terminating at this stage. A very few (1-3 per worm) activate to form normal-looking, motile spermatozoons.
BA969 spe-6(hc163) III; spe-27(it132) dpy-20(e1282) IV. Dpy. spe-6(hc163) is a recessive suppressor of spe-27(it132). spe-6(hc163) also suppresses spe-8, spe-12, spe-29 and other spe-27 alleles. Causes precocious spermatid activation. Fertile between 15-25C.
BA971 spe-27(it132) dpy-20(e1282) IV. Temperature sensitive spe-27 allele. Leaky sterile at 20C. Males at 20C produce spermatids that form spikes in pronase. Males are fertile. Temperature sensitive dpy-20 allele. Maintain at 15C.
BA975 spe-6(hc163) III; spe-29(it127) dpy-20(e1282) IV. spe-6(hc163) suppresses the self-sterility of spe-29 in this strain. Self-sterile at 25C.
