hyEx167 [4.5kb aff-1p::GFP transcriptional fusion + rol-6(su1006)]. Shows cytoplasmic GFP expression in embryonic hyp5. In L1 hermaphrodite larva, aff-1::GFP is expressed in pharyngeal muscle 3 and 5, in sheath cells of chemosensory neurons, and in tail neurons. In L3 hermaphrodites, the transgene is expressed in the anchor cell; this expression proceeds in L4 along with expression in the utse cells, the seam cells and cells of vulval rings A and D. In adults, aff-1::GFP is expressed in the sheath cells of chemosensory neurons and in head interneurons, uterus toroids 2 and 4, in the vulva VulD, utse, and seam cells. Worms of hyEx167 are slightly Egl. Maintain by picking Rollers.

A 1.2 kb deletion in aff-1 (C44B7.3) which introduce stop codon after alanine 47. AFF-1 is a type I membrane protein necessary and sufficient for specific cell fusion events during embryonic and larval development. Temperature sensitivity was not detected. At 20° the fusion of hyp5 in the embryo does not occur as well as anchor cell (AC) fusion, vulval cells fusion of the A and D rings and the terminal fusion between the seam cells late in L4. 6% L1 rod-like lethal and 0% embryonic lethal. Adults are completely Egl, and partially Unc, Pvl. In addition, only 2% of AC in the mutant worms undergo fusion. These animals give very low brood size (16 progeny per worm) and 3.4% of the worms are sterile. This strain gives very small brood size and hence grows slowly. Originally from Shohei Mitani, Tokyo Women's Medical College, Tokyo, Japan.

Slow postembryonic development. Reduced brood size. Previously known as pep-2. [NOTE: the genotype of this strain was previously incorrectly annotated as lg1601. The correct allele name is lg601.] Reference: Meissner B, et al. J Biol Chem. 2004 Aug 27;279(35):36739-45.

antIs30 [attP-f + Cbr-unc-119(+) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. antIs30 was inserted into ttTi5605 on LG II using MosSCI. GFP expression in pharynx is very weak (as it is single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. Reference: Yang FJ, et al.

antIs31 [attP-f + Cbr-unc-119(ant40) + glh-2p::phiC31 + rol-6(partial) + myo-2p::GFP + attP-r] II. Unc. antIS31 has been found to self-excise; check for GFP expression periodically to retain the insertion. GFP expression in pharynx is very weak (as it is in single copy) and is easiest to see during the L1-L3 stages. This strain contains a phiC31 docking site and can be used for precise single-copy integration of transgenes via recombination mediated cassette exchange. The docking site contains inverted phiC31-attP sites flanking phiC31 integrase expressed from the glh-2 germline promoter. Integration constructs need to have inverted phiC31-attB sites that flank the intended sequence to be inserted. antIs31 was derived by CRISPR/Cas9 knockout of Cbr-unc-119 in antIs30 creating ant40, a 691 bp deletion in Cbr-unc-119. Because antIs31 does not rescue unc-119(ed3), BRC566 facilitates the use of Unc-119 rescue as a selection marker for transgene insertions. Reference: Yang FJ, et al.

kqEx73 [pat-3(sp) + rab-3::RFP + cki-1::GFP]. Pick RFP+ to maintain. kqEx73 carries a form of pat-3 gene with splicing defects; rescues pat-3 null allele. pat-3(sp) is a frameshift mutation in the splice acceptor region (ag to aa) that abolishes conserved interaction domains such as the NPxY motifs and creates a splice variant with an extra 19 amino acids. The pat-3(sp) animals not only produce mutant pat-3, but also express the regular splice form due to utilization of an unusual splice acceptor. Abnormal Distal Tip Cell migration and pat-3 gene splicing (intron 7) defects. Reference: Kihira S, et al. PLoS One. 2012;7(8):e42425.

Maintain by picking Lon non-Unc. Throws Lon non-Unc, Lon Unc Vab (bent head, tails very thin), and Lon Unc Mel (kinker, temperature-sterile).

Animals with the duplication are WT. Animals without the duplication are Nob (NO Back end; 100% lethal). Pick wild-type to maintain; typically segregates about 50% wild type progeny and 50% Nob larvae.

Animals with the duplication are WT. Animals without the duplication are Nob (NO Back end; 100% lethal). Pick wild-type to maintain. The Dpy and Unc phenotypes are not visible in the Nob background. ct223 is recessive.

Heterozygotes are WT and segregate WT, DpySteriles and dead eggs. Pick wild-type heterozygotes to maintain. ct281 homozygotes show Nob phenotype: approximately 80% of homozygous embryos arrest at about the time of hatching with fairly normal anterior development but a severely deformed posterior with a variable knob-like shape; approximately 20% fail to enclose and do not hatch. ct281 is a 4.7kb deletion removing intron 5, exon 6, and the 3'UTR of the pal-1 gene.

Heterozygotes are WT and segregate WT, DpySteriles and dead eggs. Pick wild-type heterozygotes to maintain. ct224 homozygotes show Nob phenotype: approximately 80% of homozygous embryos arrest at about the time of hatching with fairly normal anterior development but a severely deformed posterior with a variable knob-like shape; approximately 20% fail to enclose and do not hatch. ct224 is a 4.2kb deletion removing exon 1 through exon 6 of the pal-1 gene.

WT hermaphrodites that segregate WT, Dpy Steriles and Nob larvae. The Nob phenotype results in 100% lethality. Maintain by picking WT.
