Maintain by picking Unc.

Cytologically they exhibit a reduced level of HIM-3 loading and fewer stretches of SYP-1 than WT. In diakinesis-stage oocytes, they contain a mixture of bivalents and univalents. Maintain by picking Unc.

AV307 C. elegans syp-1(me17) V/nT1 [unc-?(n754) let-? qIs50] (IV;V). Show Description
Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc syp-1(me17) homozygotes, and dead eggs (nT1 homozygotes). syp-1(me17) homozygotes produce 95% dead embryos and 38% males. Cytologically they lack chiasmata in diakinesis-stage oocytes, exhibit persistent polarized nuclear organization during earlier meiotic prophase, lack synaptonemal complexes, and exhibit unstable pairing of homologous chromosomes. qIs50 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and a gut promoter (F22B7.9) driving GFP in the intestine.

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.

Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to David Baillie.
