HG231 exhibits an approximately 20% increase in mean, median and maxium lifespans compared to N2. HG231 exhibits somewhat reduced fertility and somewhat longer development time than N2. It has a normal appearance, movements and mating behavior. It's swimming rate in liquid is slightly higher than N2. STS mapping indicates the most likely location for age-2 is on LG I.

Heterozygtes are WT. Hets segregate WT, UncBli and DpyLet. ct42 homozygotes are inviable at all temperatures (recessive non-conditional larval lethal). ct42 is dominant temperature sensitive maternal effect lethal. ct42 hets give more inviable progeny at 25C than at 15C. dch-1 was previously called let-354(ct42).

Dominant ts maternal-effect embryonic lethal. Embryos arrest prior to morphogenesis or at two-fold. Non-ts recessive mid-larval lethal. Maintain at 15C. Freezes poorly.

Dominant temperature sensitive maternal-effect embryonic lethal. Maintain at 15C. Heterozygotes are WT. hIn1 homozygotes are Unc. Early cleavage spindles small and misoriented, cytokinesis often incomplete. Recessive non-temperature sensitive maternal-effect embryonic lethal (but sterile in conjuction with unc-59).

Dominant ts maternal-effect embryonic lethal. Embryos show extensive cytoplasmic blebbing, often accompanied by small spindles and incomplete cytokinesis. Two cell embryos divide synchronously. Embryos arrest with eight to several hundred cells. Recessive non-ts maternal-effect embryonic lethal. Null may be WT. Maintain at 15C.

sbEx133 [mel-11::GFP + rol-6(su1006)]. Maintain by picking Rollers.

Heterozygotes are WT. ct46 is a dominant, temperature sensitive maternal effect lethal. ct46 homozygotes are viable and fertile at 15C. b284 is a non-conditional, recessive maternal effect lethal. Heterozygotes give more viable progeny at 15C than 25C.

5-bp deletion. Superficially wild-type. Reference: https://www.micropublication.org/journals/biology/micropub-biology-000169/

This strain can grow at 11.5C but is embryonic lethal at 15C and above. Temperature shifts in late embryogenesis or in larval stages result in defects in many asymmetric cell divisions in postembryonic develoment.

Heterozygotes are green and segregate green WT, dead eggs and nonGreens that lay dead eggs with the defects in spindle organization, chromosome segregation, and cytokinesis.

zdIs5 [mec-4p::GFP + lin-15(+)] I. Homozygous nT1[qIs51] are inviable. mec-4::GFP is expressed in touch neurons. Heterozygotes are strong Egl Psa GFP+ and segregate dead eggs and non-GFP Unc Egl Psa that give only dead eggs at 25C.
