Heterozygotes are WT and segregate WT, dead eggs and Uncs. At 25C the Unc Spds are Sterile; at 16C the Unc Spds are fertile but produce mostly dead eggs. Unc Spd animals will exhibit a fully penetrant maternal-effect embryonic lethal phenotype if shifted to 25C at the L4 stage. unc-13 spd-2 homozygotes may be propagated at 16C but may become sick causing immense frustration!

Homozygous males have tail and mating defects. ES=3. Cloned: ORF C26D10.5 encodes a type-I membrane glycoprotein with a single TM domain. ajm-1 was formerly known as jam-1 (Junction Associated Protein) and "the gene encoding the antigen recognized by the monoclonal antibody MH27." jcIs1 consists of pJS191, C45D3 and pRF4.

Up to 30% of the homozygotes are Sterile at 16C. hT2[qIs48] homozygotes are dead. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

Temperature sensitive: maintain at 15-20C. Reduced number of progeny and mortal germline phenotype at elevated temperatures. Mitochondria Targeting Sequence (mts) added to the 3xFLAG::GFP-tagged endogenous wago-4 locus localizes tagged WAGO-4 to mitochondria. This allele was introduced into 3xFlag::GFP tagged endogenous wago-4 locus in parental strain YY1325.

Temperature sensitive: maintain at 15-20C. Reduced number of progeny and mortal germline phenotype at elevated temperatures. Engineered mutations of FG repeats in three Vasa like GLH proteins (GLH-1, GLH-2 and GLH-4). glh-1(jog50) is F to A substitution. glh-4(jog16) is F to A substitution. glh-2(jog49) is a deletion of the FG repeats. This strain exhibits a subtle change in germ granule composition while maintaining their architecture. WAGO-4 is mislocalized to the cytoplasm leading to compromised function.

Rollers. n1270 is phenotypically wild type. neEx1[LIT-1::GFP + rol-6(su1006)]. LIT-1::GFP has full length LIT-1 fused to GFP in a YAC. Pick Rollers to maintain.

n1790 causes a partially penetrant "rod-like" larval lethal phenotype (17% at 20C) and a partially penetrant vulvaless defect (50% at 20C). A Smg mutation enhances these phenotypes. The n1790 mutation is a nonsense change at codon 352.

n2515 suppresses the let-60(gf) Muv phenotype. Isolation of lin-1 causes no significant vulval defect; it is a missense mutation that changes Proline 384 to Leucine. dpy-13 is a linked marker.

Homozygous maternal effect lethal mutation balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP am315 homozygotes (maternal effect lethal). Homozygous nT1[qIs51] inviable. Pick wild-type GFP and check for correct segregation of progeny to maintain. 3xFLAG epitope allows antibody detection of full-length PCN-1. Reference: Kocsisova Z, et al.

qaIs8400 [let-858p::Ov-GST-3 + rol-6(su1006)]. Called AK1 in the reference article. The Ov-GST-3 gene was amplified from genomic DNA of O. volvulus with 1µM of the sequence specific primer 5'Klon and 3'Klon (5'Klon: 5'-GGCGTACGATGTCAAGATTTCCTCAACAAG-3'; 3'Klon: 5'-GGTCTAGATTTATTTAGGAATGATTGAATCGGTCG-3'; representing bases 4 - 25 and the complementary sequence of bases 821 - 841 of the published Ov-GST-3 cDNA (AF203814); bold underlines indicate restriction sites for Pfl23II (SplI) and XbaI, respectively; dotted underline indicates the start codon for translation; italics indicates the conserved sequence for the polyadenylation signal for transgenic transcript processing; the 8 5'-nucleotides of primer 3'Klon and the fourteen 5'-nucleotides of primer 5'Klon do not correspond to the template and introduce the sequences to the amplicon), 200 µM of each deoxynucleotide (Gibco BRL) and 2.5 units of Taq polymerase (Gibco BRL). After an initial denaturation of 3 minutes at 93°C, 35 cycles of annealing at 55°C for 1 minute, synthesis at 72°C for 2 minutes and a 1 minute denaturation at 93°C were performed, followed by a final extension at 72°C for 5 minutes. The genomic Ov-GST-3 fragment obtained by PCR (see above) was ligated into the pGEM-T Easy vector (Promega) by TA-cloning, cleaved with the restriction enzymes Pfl23II (SplI) and XbaI (restriction sites introduced by the primer) and inserted between the unique Pfl23II (SplI) and XbaI sites of the vector pPD103.05 (kindly provided by A. Fire). The sequence of the genomic Ov-GST-3 fragment in the resulting plasmid pAK1 was confirmed by automated dye terminator, dideoxy sequencing (ABI Prism 377TM Sequencer, PE Applied Biosystems) using the PCR primers (see above). The pAK1 DNA was injected in combination with the marker plasmid pRF4 [rol-6(su1006)] into the gonads of N2 C. elegans at a concentration of approximately 100 ng/µl for each plasmid. Transgenic worms were identified by the selectable Roller marker phenotype and the stable transmitting line AK1ex (AK1 extrachromosomal) was established. Integration of the extrachromosomal arrays was achieved by irradiation of AK1ex worms with 3600 rad (1 rad = 0.01 Gy) of x-rays (x-ray chamber: RUM 9421-070-77002, Philips, Netherlands; dosimeter: PTW-SN4, PTW, Germany). The progeny of these worms was then screened for 100% transmittance of the Roller phenotype to obtain the C. elegans line AK1int (AK1 integrated) with the chromosomally integrated transgenes.
