ctIs33 [pal-1::GFP + rol-6(su1006)]. Heterozygotes are WT and segregate WT, DpySteriles and dead eggs. Pick wild-type heterozygotes to maintain. ct224 homozygotes show Nob phenotype: approximately 80% of homozygous embryos arrest at about the time of hatching with fairly normal anterior development but a severely deformed posterior with a variable knob-like shape; approximately 20% fail to enclose and do not hatch. ct224 is a 4.2kb deletion removing exon 1 through exon 6 of the pal-1 gene. ctIs33 carries a non-rescuing pal-1::GFP fusion containing ~7kb 5' of the SL1 splice site through part of exon 5 fused to GFP. GFP expression is primarily embryonic and limited to a few cells; not visible except at high magnification. Reference: Edgar LG, et al. Dev Biol. 2001 Jan 1;229(1):71-88.

ctIs39 [hbl-1p::GFP::NLS::hbl-1 3'UTR + rol-6(su1006)]. Rollers. Reporter encodes the first 133 amino acids of HBL-1 followed by GFP with SV40 NLS and 1.4 kb of hbl-1 3' UTR. Reference: Fay DS, et al. Dev Biol. 1999 Jan 15;205(2):240-53.

svDp1 [sur-5::GFP] (III;f). svDp1 was derived by insertion of a sur-5::GFP marker into sDp3(III;f). Pick GFP+ wild-type to maintain. svDp1 rescues ct224. ct224 homozygotes (lacking GFP expression) show Nob phenotype: approximately 80% of homozygous embryos arrest at about the time of hatching with fairly normal anterior development but a severely deformed posterior with a variable knob-like shape; approximately 20% fail to enclose and do not hatch. The duplication is lost in about 30-40% of embryos. Reference: Edgar LG, et al. Dev Biol. 2001 Jan 1;229(1):71-88.

Heterozygotes are Unc and segregate Uncs, dead eggs, and non-Uncs (dsb-1 homozygotes), which produce 99% inviable embryos due to meiotic nondisjunction. Pick Unc to maintain and check for correct segregation of progeny. we11 is a TCA to TAA nonsense mutation in the dsb-1 coding sequence that introduces a premature stop after leucine 96.
