fjSi3 [HA_2×FLAG::C04F12.1 + Cbr-unc-119(+)] II. Single-copy insertion in the MosSCI locus ttTi5605 (LG II). The HA_2×FLAG::C04F12.1 transgene was designed to express a protein with an HA tag and a double FLAG tag inserted after S21 of C04F12.1. The linker sequence between the HA tag and the double FLAG tag has a NotI site. The insertion can be checked by PCR with the following primers: GGAGCCGATTTGTTCCAGTC (at the 3'-side of C04F12.1) and ATCGGGAGGCGAACCTAACTG (near ttTi5605 on LG II). vsra-1 is also known as csr-2/C04F12.1.

fjSi19 [rpl-21p::2×HA::C04F12.1 + Cbr-unc-119(+)] II. Single-copy insertion in the MosSCI locus ttTi5605 (LG II). The 2×HA::C04F12.1 transgene was designed to express a protein with a double HA tag at its N-terminus, using a strong ubiquitous promoter (rpl-21p). The linker sequence between the two HA tags has a NotI site. The insertion can be checked by PCR with the following primers: GGAGCCGATTTGTTCCAGTC (at the 3'-side of C04F12.1) and ATCGGGAGGCGAACCTAACTG (near ttTi5605 on LG II). vsra-1 is also known as csr-2/C04F12.1.

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 homozygous tm1637; fj54 double mutants. The vsra-1 mutation enhances the defects caused by the csr-1 mutation. The fj54 deletion causes a frame-shift to stop the translation of both PAZ and Piwi domains. tm1637 can be detected by PCR with the following primers: AAGCAGTTCTTCAAGACTGGTC and TTGTCCACTCGCACTTTGTG. The fj54 deletion can be checked by PCR with the following primers: AAGAAATACCAATGCGGAGGCA and TTCACGGCTCTTTGCAGTTTCA. vsra-1 is also known as csr-2/C04F12.1. Reference: Tabara H, et al.
