Hermaphrodites are sterile; Males are fertile. Hermaphrodites lay oocytes (produce a few fertile eggs and many oocytes). Produce viable progeny when mated to males. Hermaphrodites produce 10X more self progeny at 20C (2.5/herm) than at either 16C or 25C.

Unc. Leaky sterile at 20C; tighter at 16C and 25C. Easier to propagate as if male-female strain.

sEx14133[rCesB0350.2f::GFP + pCeh361]. Maintain by picking WT. WT animals are GFP+. Strain construction supported by Genome British Columbia and Genome Canada. Please acknowledge McKay et al, Cold Spring Harbor Symposia on Quantitative Biology 68: 159-169 2004 (WBPaper00006525).

Heterozygotes are WT and segregate WT, Unc-36 and dead eggs. Maintain by picking WT. Original isolation: BO strain BC1261 unc-22(s727) hermaphrodite heat shocked for 1 hour at 34C. Crossed to N2 strain BC1270 unc-22(s7) unc-31(e169)/nT1 IV; +/nT1 V. Picked individual WT hermaphrodites. Screened for the absence of gravid Unc-22. Retained strain as BC1379. Balanced over eT1: BC1379 unc-22(s727)[BO]/nT1[N2] IV; sDf31[BO]/nT1[N2] hermaphrodite crossed to BC 1265 dpy-18(e364)/eT1 III; unc-46(e177)/eT1 V. Pick WT hermaphrodites that twitch in 1% nicotine. Retained one strain that segregated Unc-36 as BC1428. Pseudolinked sDf31 to dpy-18: BC1428 +/eT1 III; sDf31[BO]/eT1 V crossed to BC 1265 dpy-18/eT1 III; unc-46/eT1 V male. Picked WT hermaphrodite F1. From strains segregating Unc-36 but no Dpy or Unc-46 or DpyUnc-46, cross WT hermaphrodites to BC1265 males. From strains producing Dpy, crossed individual WT males to BC70 eT1;eT1. From each cross, crossed WT X WT. Kept one strain producing on Dpy or DpyUncs as S-H716 male. Picked one hermaphrodite to start BC1519. Comments: 1) The LGV region balanced by eT1 should be all BO. 2) Probably the rest of the genome still has a considerable amount from BO since it was crossed to N2 only 4 times. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to David Baillie.

Heterozygotes are WT and segregate WT, Unc-36, DpyUncLet and dead eggs. Lethal as sterile adult. Maintain by picking WT. [7/94: No longer throwing eT1 Unc-36's. May have picked up a lethal mutation on one of the eT1 chromosomes. Also, appears to be lethal in mid-late larval stage rather than as adult.]

srl-2 is a recessive suppressor of the s1040 temperature sensitive lethal phenotype. srl-2 has no effect on the Roller phenotype of s1040. (At 20C, s1040 homozygotes arrest development at mid-larval stage. At 15C, s1040 homozygotes are viable weak left-handed rollers.) Maintain at 20C to select for retention of suppressor. Animals at 20C will be DpyUncRol.
