ojIs1 [pie-1p::GFP::tbb-2 + unc-119(+)]. Maintain under normal conditions. Reference: Strome et al. (2001) Mol Biol Cell (6):1751-64.

Heterozygotes have myo-2::GFP [qIs48] strongly expressed in the pharynx and are viable at 25C. 100% of sep-1 homozygotes are strongly Sterile Unc at 25C (at 20C, 100% are Sterile but no so Unc). 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.

C. briggsae strain. Reduced fecundity at 20°C and 25°C. Generated by CRISPR/Cas9 in AF16 background, prg-1(how21) is a 5 bp deletion located 47 bp downstream of the start codon that causes frameshift. prg-1(how21) is presumed null; consistent with previous findings that the stability of piRNAs and Piwi protein are co-dependent in C. elegans, the overall abundance of 21 U-RNAs in Cbr-prg-1(how21) was reduced to ~1% of wild-type. Reference: Pastore B, et al. RNA Biol. 2022 Jan;19(1):1276-1292. doi: 10.1080/15476286.2022.2149170.

Temperature sensitive: maintenance at 15-20C. Reduced number of progeny at elevated temperatures. PH domain added to the 3xFLAG::GFP-tagged endogenous wago-4 locus in parental strain YY1325. This allele localizes WAGO-4 to the plasma membrane, but de-localization is not complete (some residual germ granule signal is detected).

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.

Temperature sensitive: maintain at 15-20C. Reduced number of progeny at elevated temperatures. wago-4(jog272) is an engineered Y611E point mutation predicted to disrupt small RNA binding and exhibits a diffuse cytoplasmic localization. This allele was introduced into 3xFlag::GFP tagged endogenous wago-4 locus in parental strain YY1325.
