ML2936 C. elegans nmy-1(mc90[nmy-1::gfp]) X. Show Description
Maintain at 15C. nmy-1(mc90) allele induces almost complete sterility at 25C. mc90 is a CRISPR-engineered mutation in nmy-1 at the position corresponding to the allele nmy-2(ne3409) changing NMY-2 Leucine-981 to Proline, which is conserved among nonmuscle myosins. mc90 was introduced in parental strain ML2540, which carries a GFP-tag in the endogenous nmy-1 locus.

MP130 C. elegans sup-40(lb130)/+ I; unc-8(e15) IV; egl-1(n487) V. Show Description
lb130/+ dominantly suppresses the e15 backing defect and causes recessive sterility. Three phenotypes are present in this strain: backing steriles (lb130 homozygotes), backing fertiles which are bloated (heterozygotes), and non-backing coiled Unc animals which are fertile and bloated (sup-40(+)). Maintain strain by picking fertile animals which can back. egl-1(n487) is included in the strain to facilitate identification of lb130 homozygotes, which grow slowly; their sterility contrasts with the bloating of lb130/+ heterozygotes.

MQD1779 C. elegans daf-2(hq63[daf-2::ICR::NLS::gfp::mNeonGreen::NLS]) III. Show Description
Nuclear Ultrabright GFP::mNeonGreen Fluorescent protein (NuGFP) tag inserted downstream of the endogenous daf-2 gene locus by CRISPR/Cas9 engineering. NuGFP cassette is composed of an intercistronic region (ICR) from the C. elegans SL2-type operon, a SV40 nuclear localization sequence (NLS), the coding sequence of GFP, the coding sequence of mNeonGreen, and egl-13 NLS. The expression of NuGFP is tied to that of the endogenous daf-2, but after trans-splicing, the NuGFP protein is synthesized independently of DAF-2. This high-sensitivity daf-2 expression reporter was readily detectable in most C. elegans cells throughout development and adulthood. Reference: Zhang Y, et al.

MT1373 C. elegans lin-13(n387)/unc-32(e189) III; him-5(e1467) V. Show Description
Maintain by picking wild-type animals raised at 25C. Heterozygotes will be wild-type and segregate wild-type, Unc, Sterile Muv, and males. The phenotype of homozygous lin-13 hermaphrodites segregating from a heterozygous mother depends on the temperature at which the strain was grown. At 25C, homozygous hermaphrodites segregating from a heterozygote are both Muv and sterile. At 20C, ~1/2 of hermaphrodites segregating from a heterozygote are sterile, but only a few are Muv. At 15C, hermaphrodites segregating from a heterozygote are almost wild type in appearance and fertility. However, if the progeny of these 15C animals are grown at 15C, all are sterile and some are Muv. If the progeny of these 15C animals are grown at 25C, then some animals arrest during larval growth and the rest are both sterile and Muv. The male phenotype similarly is heat sensitive; only males that are the progeny of lin-13 hermaphrodites and are grown at 20C or 25C have ventral protrusions. Reference: Ferguson EL & Horvitz HR.

MT14728 C. elegans mfap-1(n4564 n5214) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). Show Description
Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP mfap-1 homozygotes. Pick WT GFP and check for correct segregation of progeny to maintain. mfap-1(n4564 n5214) mutants exhibit temperature-sensitive lethality: at 15°C, (n4564 n5214) homozygous animals grow and behave similarly to wild-type; at 20°C mutant animals grow more slowly, have few progeny and are hyperactive; at 25°C the mutant strain is embryonically lethal. qIs48 is an insertion of ccEx9747 (carries myo-2::GFP, pes-10::GFP, and a gut enhancer fused to GFP) onto the hT2 chromosome and is homozygous lethal.
