Temperature sensitive: sterile at 25C. Maintain at 15C. Him. Eri. Due to a direct repeat the exact site and sequence of the 23 bp eri-1(mg366) insertion is unclear, however, the insertion lies in exon 6 of T07A9 between nucleotide positions 35215 and 35204 of cosmid T07A9 and includes 23 or these 32 nucleotides tttatcgaaaaaaaaacaggcactttatcgaa.

sid-1(qt160) V. Null allele. Systemic RNAi deficient. This sid-1(qt160) allele is designed as a efficient Cas9 target for reversion to wild-type sid-1 function in co-conversion experiments. Successful reversion re-enables RNAi targeting any gene of choice. 44 nt sid-1 loss of function cassette inserted into exon 2 (Chr V: 5120123..5120124) contains exogenous crRNA site UcrRNA_AW1, stop codons in all three frames, and KpnI site, which also induces a frame shift. sid-1 LOF cassette sequence: ccgccgcactggacaaacttccctaactgactaaggtaccgata.

frSi17 [mtl- 2p::rde-1 3'UTR] II. frIs7 [nlp-29p::GFP + col-12p::DsRed] IV. frSi17 inserted into ttTi5605 site using CRISPR/Cas9 engineering. RDE-1 activity is rescued in the intestine, making animals RNAi-deficient except for intestinal tissues. The frSi17 insertion can be detected using a primer within the mtl-2 promoter (jep1061: aacaaacgtgggatgtaacc) in combination with downstream primer in rde-1 (jep2817 tcatactcgtagtattcccg), producing a 786 bp product if insertion is present. rde-1(ne300) can be genotyped by sequencing the PCR product from jep2299: gaacaacgacaatcgagcacca and jep3108: ATcttgtgaccgaactgtcc.
