dvIs27 [myo-3p::A-Beta (1-42)::let-851 3'UTR) + rol-6(su1006)] X. Rollers. Temperature sensitive: needs to be propagated at 15C. Upshift larval animals to check that the worms get paralyzed and give offspring that arrest as eggs/early larvae. This strain produces low levels of beta amyloid peptide even when grown at low temperature, and therefore there is always some selection for loss of transgene copies. It is recommended to maintain growing stock plates at 15-16 degrees C by transferring small numbers of animals each generation rather than by "chunking", which increases the effective population size and therefore the chance of a relatively rare transgene loss, and then this revertant taking over the population. The strain should also be frozen shortly after being received. This strain can only be sent to academic users and not to commercial organizations.

Temperature sensitive. At 22.5C, maternal effect embryonic lethal. Temperature shift-up to 22.5C during embryogenesis results in animals with Egl, Pvul and Psa (phasmid socket absent) phenotypes. Shift-up to 25C results in growth arrest at larval stage. The T cell division can be symmetric as in lin-17 mutants. At 15C, nearly WT. Males grown at 15C can mate very well. psa-1 encodes a homolog of yeast SW13, a component of the SWI/SNF complex. Sequence data of this strain revealed the mutation is actually GTC/CCC/TCA to GTC/CTC/TCA causing a P86L substitution (G. Hayes).

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. (jep3108 is not present in the frSi17 transgene) Reference: Watts JS, et al. G3 (Bethesda) 2020 Nov 5;10(11):4167-4176. PMID: 32943454

frSi21 [col-62p::rde-1 3'UTR] II. frIs7 [nlp-29p::GFP + col-12p::DsRed] IV. frSi21 inserted into ttTi5605 site using CRISPR/Cas9 engineering. RDE-1 activity is rescued in adult epidermal tissues, making animals RNAi-deficient except for hypodermal (skin) tissues from the young adult stage. The frSi21 insertion can be detected using a primer within the col-62 promoter (jep2245: caaaaaggcgggatgagcag) in combination with downstream primer in rde-1 (jep2817 tcatactcgtagtattcccg), producing a 965 bp product if insertion is present. rde-1(ne300) can be genotyped by sequencing the PCR product from jep2299: gaacaacgacaatcgagcacca and jep3108: ATcttgtgaccgaactgtcc (jep3108 is not present in the frSi21 transgene).
