lin-3(-) heterozygous balanced strain containing single copy MOS-mediated insertion of csSi1 transgene encoding lin-3L (long) splice isoform, expressed under control of the lin-3 promoter. The transgene partially rescues lethal and Vulvaless phenotypes (but not sterility) of lin-3 mutants, which can be recognized by absence of myo-2::GFP from the nT1 balancer. Pick GFP+ to maintain.

lin-3(-) heterozygous balanced strain containing single copy MOS-mediated insertion of csSi1 transgene encoding lin-3XL (extra long) splice isoform, expressed under control of the lin-3 promoter.

csEx436 [lpr-3 (fosmid WRM619dE09) + myo-2p::mCherry]. Pick mCherry+ animals to maintain. cs231 is a Crispr/Cas9-induced null allele of lpr-3: a 13 nucleotide deletion in exon 1 results in frameshift. Homozygous mutants are embryonic lethal, but are rescued by csEx436 containing lpr-3(+) fosmid WRM619dE09. NOTE: lpr-3(cs231) should be considered the canonical allele as ok2351 also perturbs expression of adjacent gene lpr-6. Reference: Forman-Rubinsky R, Cohen JD and Sundaram MV.

Heterozygotes are WT GFP+ and segregate non-glowing hus-1 homozygotes and very rare homozygous hT2 glowing animals, and dead eggs. qIs48 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and gut promoter driving GFP in the intestine. hus-1(op244) mutants from homozygous parents show an incompletely penetrant maternal effect embryonic lethality. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

Healthy and fertile in standard lab conditions, but unable to adapt to 1% oxygen. When hif-1(+) animals are incubated in1% oxygen, >94% will complete embryogenesis and larval development. In contrast, hif-1(ia4) mutants exhibit 66% embryonic lethality and 9% larval lethality in 1% oxygen. The requirement of hif-1 is alleviated if the oxygen level is increased to 2%. The ia4 mutation is a 1231 bp deletion of the second, third, and fourth exons, which encode much of the helix-loop-helix and PAS domains. Analysis of ESTs suggests that there are at least 4 alternatively spliced hif-1 transcripts. The ia4 deletion introduces a frameshift and a premature stop in the three longest forms.
