jcIs1 [ajm-1::GFP + unc-29(+) + rol-6(su1006)] IV. Loss of cell fusion in hypodermis (epithelial fusion failures). Viable and fertile as homozygotes. Tail-spike defect in all young larvae, less visible in older larvae and adults. oj55 appears to cause incomplete loss of function, as many cells fuse in postembryonic development. 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.

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.

Pick GFP+ to maintain. sprDf1 is a ~0.25 Mb microdeletion allele on the left arm of chromosome V that removes 32 adjacent protein-coding genes, including mex-5. Heterozygous animals (GFP+) are fertile, but sometimes die by bursting, will have polynucleated embryos, and form uterine tumors ~6 days after hatching. sprDf1 homozygotes (GFP-) have maternal effect lethality, are small, sterile, form large uterine tumors that consist of poly nucleated embryos, have squashed vulvas, are uncoordinated, and die by bursting within eight days of hatching. nT1 homozygotes are inviable (dead eggs).
