tm1086 is homozygous lethal. Maternally rescued. Fails to produce viable progeny due to a defect in repairing meiotic DNA double-strand breaks. Chromosomes are visibly aggregated at diakinesis. Maintain by picking GFP progeny and checking that the non-GFP progeny that are produced fail to give viable progeny. 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 a gut promoter driving GFP in the intestine, and is homozygous lethal.

Superficially wild-type. ups39 is a CRISPR-engineered deletion within daam-1. daam-1(ups39) encodes an in-frame stop codon near the start of its FH2-coding sequence, and a 1-nt frame shift due to the LoxP site, and is thus predicted encode a non-functional formin.

Temperature sensitive. At 15C the animals are essentially WT, but with a reduced brood; males mate well. Embryos raised at 25C will result in 3-fold/L1 arrest (Mup). Larval shift to 25C will result in sterile hermaphrodites but males that are fertile.
