Cre inserted into the endogenous egl-3 locus by CRISPR. Pan-neuronal expression of Cre. Allele generated by SUNY Biotech. Please contact Oliver Hobert prior to publishing work using this strain.

Pale, scrawny appearance, probably due to starvation. Hyperactive, backs frequently, egg laying constitutive, slow pharyngeal pumping. Probably null (based on sequence, S. Nurrish). Suppresses activated GOA-1 and partially suppresses egl-3(rf). Lethal in combination with eat-16(rf). Previously called sag-1. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

s1775 homozygotes die as embryos or L1 larvae. Heterozygous animals are WT and segregate WT, Twitcher lethals and dead eggs. nT1 appears to have a lethal mutation.

Dominant, gain-of-function mutation in egl-30; missense M244I. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Hyperactive. Small. Spicule protruder. Coiler. Throws males.

ad810 is homozygous lethal. ad810/+ is Egl and it suppresses gpb-2 (a.k.a. eat-11). In DA1077, heterozygotes are Egl. Strain throws Lon Males.

Egl. Semi-dominant suppressor of eat-11.

ad810 is homozygous lethal. ad810/+ is Egl and it suppresses gpb-2 (a.k.a. eat-11). In DA1096, heterozygotes are Egl. Throws Lon males.

ad810 is homozygous lethal. ad810/+ is Egl and it suppresses gpb-2. gpb-2 phenotype is rather subtle: they are slightly starved, slightly longer than normal, and tend to be loopy in their movements (they make abnormally deep bends). Hets should be Egl and non-Eat. On most E. coli strains gpb-2 grows rather poorly, especially if the plates are older so that there is a thick and tough lawn. On such plates there will be a lot of gpb-2 larval arrest, and those that don't arrest will grow slowly. The hets should easily outgrow the gpb-2 homozygotes. [gpb-2 is also hypersensitive to the drug arecoline: they won't grow on 5 mM. The hets will grow even better than WT on 5 mM arecoline.] gpb-2(ad541) previously called eat-11(ad541).

Suppressor of gpb-2 (a.k.a. eat-11) arecoline hypersensitivity. Unc. Egl.

Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ad810 homozygotes. Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain.

Heterozygotes are WT and segregate WT, Egls which give only dead eggs, dead eggs, and mid-larval lethals (hT1 homozygotes)

Presumptive gain-of-function mutant shows defects in salt-food associative learning and olfactory learning. Reference: Tomioka M, et al. 2006 Sep 7;51(5):613-25. PMID: 16950159

Defective response to short wavelength light; response strongly reduced but not eliminated. All other characteristics seem wild type, including reponse to mechanosensory stimuli. Strong, probably null, allele. This mutation also blocks the coordinated light response of unc-31(e928) and egl-30(ad805). To identify lite-1 homozygous mutants when crossing into different backgrounds, use a fluorescence stereomicroscope with a GFP filter and zoom to the hightest magnification (60-100X) to distinguish Lite from non-Lite animals. This works best when the animals are mired in thicker parts of the food to slow their spontaneous locomotion but not their response to light. Scan animals around the edge of the food where it is thickest. Leave the lid of the plate off for a minute or so before starting to let the animals adjust to air currents.

syIs36 [(pLB2) egl-30(+) + pBS + (pMH86) dpy-20(+)]. Integrated version of syEx126 (egl-30 over-expressing line). Easily reverted.

This strain cannot be used for any commercial purpose or for work on human subjects.

syIs105 [egl-30::GFP + dpy-20(+)]. Translational fusion contains all of the presumptive 5'-transcriptional regulatory sequences, introns, and presumptive 3 regulatory sequences for egl-30, in addition to the coding sequences for GFP just 5' of the egl-30 initiating methionine. syIs105 was found to partially rescue egl-30(md186) with respect to egg laying, movement, pharyngeal pumping, and response to neurotransmitters in egg-laying assays.
