mirSi16 [flp-18p::lox2272::BFP::tbb-2 3'UTR::lox2272::ChR2-HRDC::SL2::jRGECO1a::unc-54 3'UTR + Cbr-unc-119(+)] II. mirEx131 [sra-6p::TeNL + npr-9p::ChR2-HRDC::YFP::jRGECO1a + unc-119(+) + gpa:14p::CRE]. Maintain by picking worms with YFP expression in AIB neurons. Blue fluorescence in flp-18 expressing neurons. loxP sites inserrted before first (eat-4(mir12[loxP 5'UTR])) and after second (eat-4(mir17[loxP intron2])) exon of eat-4 gene. Lite. mirEx131 contains calcium sensitive (Kd 250 nM) teal nanolantern (TeNL) in ASH and PVQ, ChR2-HRDC::YFP and jRGECO1a expression in AIB and gpa-14p:CRE. CRE under gpa-14 promoter generates a conditional eat-4 KO in ASH (NOT defective) after recombination of loxP sites in that locus and switches BFP expression in AVA to ChR2-HRDC and jRGECO1a after recombination of lox2272 sites.

Retarded heterochronic phenotype. Worms reiterate L2-stage programs, have extra seams cells, gapped alae, and >30% burst at the vulva at the L4 molt. Phenotype suppressed post-dauer. nDf51 is a 5930 bp deletion starting 1762 bp upstream of mir-241, removing mir-241, mir-48, and F56A12.6 (snoRNA).

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.
