Heterozygotes are WT and segregate WT, dead eggs and Uncs. At 25C the Unc Spds are Sterile; at 16C the Unc Spds are fertile but produce mostly dead eggs. Unc Spd animals will exhibit a fully penetrant maternal-effect embryonic lethal phenotype if shifted to 25C at the L4 stage. unc-13 spd-2 homozygotes may be propagated at 16C but may become sick causing immense frustration!

Heterozygotes are WT and segregate WT, DpyUncs, and Unc-4 animals which arrest at the L4 stage. Rarely, a recombination will occur and unc-4 and pir-1 will become unlinked. Propagate the strain by picking single WT animals and checking for correct segregation of progeny. 6/2007: Daniel Chavez notes that tm1496 may also delete part of sec-5, which could be responsible for the developmental arrest of tm1496.

opIs34 [hus-1p::hus-1::GFP + unc-119(+)]. Low-copy integrated array of 1144 bp hus-1 promoter and genomic coding sequence fused to GFP. Nuclear expression of GFP in germ cells and embryos. Integrated GFP construct completely rescues DNA damage induced cell cycle arrest defect and partially rescues DNA damage induced apoptosis of hus-1(op241).

opIs76 [cyb-1p::cyb-1::YFP + unc-119(+)]. The fusion protein partially rescues a cyb-1 null allele, so it is at least partially functional. non-Unc strain.

Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

natc-1(am138) mutant animals are resistant to excess dietary zinc, cadmium, nickel, and copper. natc-1(am138) animals are also resistant to excess heat and oxidative stress while displaying reduced lifespan.
