Maintain at 20C. Insertion of GFP cDNA (from pCM1.53, no ATG/no STOP) at the C-terminus of mes-2 between II:14388297...14388298. Reference: Paix A, et al. Genetics. 2014 Sep 23.

R06A4.7. Homozygous maternal-effect sterile deletion chromosome balanced by dpy-10-marked translocation. Heterozygotes are WT, and segregate WT, arrested mT1 aneuploids, sterile Dpys (mT1 homozygotes), and ok2480 homozygotes (maternal-effect sterile). Pick WT and check for correct segregation of progeny to maintain. External left primer: AGAAGTTTCGTGCTCCGTGT. External right primer: CGTCTCTTCGCATAGAACCC. Internal left primer: GTATCGAGGTTGGCGACATT. Internal right primer: CGTGCCAAGTTTCCAATTTT. Internal WT amplicon: 3364 bp. Deletion size: 1262 bp. Deletion left flank: CTATGGCCAAACAAAAGTTCACAGAGAGAA. Deletion right flank: GCCAATCACAGCGTGTCGACATGCGGGTGA. Insertion Sequence: GAA.

Heterozygotes are WT and segregate WT, DpyUnc and Uncs which give sterile progeny (maternal effect sterile: the progeny from mutant mothers are sterile). The mutation is a strict mel, fully penetrant, and fully expressed. Sterility is due to a failure in germ-cell proliferation.

axIs1613 [pie-1p::GFP::histone H2B::mes-2 3'utr + unc-119(+)]. Transgene is prone to silencing -- maintain at 25C. Transgene is slightly unstable. Pick non-Unc, GFP+ worms to maintain.

ddIs262 [mes-2::TY1::EGFP::3xFLAG(92C12) + unc-119(+)]. TY1::EGFP::3xFLAG tag inserted in frame at C-terminus of coding sequence by recombineering. Expression of transgene confirmed by GFP.
