C28C12.7, C28C12.8. Homozygous sterile deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok1923 homozygotes (sterile adult). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: TCCCTTCCATAAATCGCTTG. External right primer: CGGTGTCGAATGAAGGTTTT. Internal left primer: GAGCCGCAATGAAAAACAAC. Internal right primer: GACTGCGGTCAAACTGACAA. Internal WT amplicon: 2109 bp. Deletion size: 939 bp. Deletion left flank: ACTAAAAAAATTCAAGAAAATGTTAATTTT. Deletion right flank: AGTGCCATGGAGAAATTCTTCGAAAACTCA.

bqSi294 [hsp16.41p::FRT::mCherry::his-58::FRT::GFP::his-58 + unc-119(+)] II. bqSi1201 [hlh-12p::FLP::SL2::mNG + unc-119(+)] IV. Heat shock induces nuclear GFP expression in the distal tip cells and nuclear mCherry expression elsewhere. Constitutive expression of diffusible mNeonGreen in the distal tip cells can mask GFP::HIS-58 signal. Might carry unc-119(ed3) or unc-119(ed9) III.
