Strain :

WormBase ID  WBStrain00054546 CGC Received  2023-06-02
Genotype  csr-1(fj54)/tmC5 [F36H1.3(tmIs1220)] IV. Laboratory  ZT
Made By  WBPerson1503 Mutagen  UV+TMP
Name  ZT60 Outcrossed  x3
Remark  Sterile csr-1 allele balanced over tmC5 labelled with Venus. Heterozygotes are wild-type with somewhat dimmer Venus signal and segregate WT Venus(+) heterozygotes, Mec Unc Venus(+) tmC5 homozygotes, and non-Venus csr-1(fj54) homozygotes (sterile, but some animals lay a small number of dead eggs). Pick wild-type Venus(+) and check for proper segregation of progeny to maintain. Homologous pairing and unpaired silencing of meiotic chromosomes are inaccurate in this csr-1 null-mutant homozygotes. The fj54 deletion causes a frame-shift to stop the translation of both PAZ and Piwi domains. The deletion can be checked by PCR with the following primers: AAGAAATACCAATGCGGAGGCA and TTCACGGCTCTTTGCAGTTTCA. The inversion-based balancer in ZT60 is more amenable to producing csr-1(fj54) homozygous males than a translocation-based balancer (ZT3). Reference: Tabara H, et al. (2023) A small RNA system ensures accurate homologous pairing and unpaired silencing of meiotic chromosomes. EMBO J, e105002. Species  Caenorhabditis elegans
