WT phenotype. Segregates WT, homozygous Dpy-10 mIn1 and homozygous Unc-4 hermaphrodites. Recombination in this interval is suppressed, and recombinant animals have not been detected in this stock.

Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Don Riddle. mIn1 pka mC6.

Dark-bodied, unmarked variant of mIn19mC6) with small broods. Presumably balances let-552 to rol-1 (hermaphrodite stock obtained from outcrossing these males to dpy-10 unc-4 was shown to balance this interval). Isolated from DR1982 as a stock that no longer segregated Dpy-10 animals. Not clear whether this strain is the result of chromosome rearrangement in DR1982, or if DR1982 stock was a mixture of mIn1(+)/mIn[dpy-10] and mIn1(+) homozygotes.

WT gross phenotype, with GFP semi-dominantly expressed in 4-60 cell embyros, pharyngeal muscle and gut. Segregates WT, brighter Dpy GFP mIn1 homozygotes and non-GFP bli-2 unc-4 homozygotes. Pharyngeal and gut GFP is easily seen in a UV dissecting microscope; early embryonic signal requires higher magnification. mIs14 occasionally crosses off mIn1[dpy-10], apparently by double recombination. Pick WT, check for GFP and check for correct segregation of progeny to maintain. mIs14 is ccEx9747 integrated into mIn1[dpy-10].

T2A::sGFP2(1-10) fused to the C-terminus of endogenous GLH-1. The T2A self-cleaving peptide separates sGFP2(1-10) from GLH-1 post-translationally so that sGFP2(1-10) disperses throughout germ cell nuclei and cytoplasm. sGFP2(1-10) is also maternally loaded into embryos, where it persists through early and mid-embryonic development. Proteins tagged with the 16aa GFP11 or M3 sequence will bind sGFP2(1-10) in the germline and early embryo to emit GFP fluorescence. Broods from DUP223 are similar to wild-type at permissive and restrictive temperatures. Transgene tag was inserted by CRISPR/Cas9 in an N2 background. [NOTE: (04/23/2021) The original stock received by the CGC was found to be carrying a second insertion, clu-1(sam131[GFP(11)::clu-1]. A new stock verified by to be carrying the correct transgene was received from DUP 05/04/2021.] Reference: Goudeau J, et al. Genetics. 2021 Apr; 217(4): iyab014. PMID: 33693628.

Heterozygotes segregate wild-type GFP+ heterozygotes, GFP+ Dpy, and sec-5 homozygotes (scrawny, small broods, abnormal gut appearance) sec-5 is homozygous maternal-effect lethal; M+Z- animals produce a few dead L1-L2 stage larvae with Vab defects. Pick GFP+ wild-type to maintain. Based upon phenotype, pk2357 is a strong loss-of-function, but likely not a null allele; molecular lesion produces a premature stop at position 389.
