ruIs38 [myo-2p(partial)::GFP + unc-119(+)] III. Derived by out-crossing AZ218 eleven times to N2.

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.

Temperature sensitive. Sterile at 25C. Maintain at 20C or below.

Heterozygotes are WT and segregate WT, DpyUncs, and Unc-4 animals which arrest at the L4 stage. Rarely, a recombination will occur and unc-4 and pir-1 will become unlinked. Propagate the strain by picking single WT animals and checking for correct segregation of progeny. 6/2007: Daniel Chavez notes that tm1496 may also delete part of sec-5, which could be responsible for the developmental arrest of tm1496.

Temperature sensitive sterile. Will throw dead eggs at 25C. 292 bp deletion.
