CF4639 C. elegans glh-1(sam140[glh-1::T2A::wrmScarlet(1-10)]) I; fib-1(mu498[wrmScarlet11::fib-1]) V. Show Description
fib-1(mu498[wrmScarlet11::fib-1]) generated via CRISPR/Cas9 insertion into parental strain DUP237; transgene contains a linker between wrmScarlet11 and fib-1. Endogenous fib-1 detectable in the germline. T2A::wrmScarlet(1-10) fused to the C-terminus of endogenous GLH-1. The T2A self-cleaving peptide separates wrmScarlet(1-10) from GLH-1 post-translationally so that wrmScarlet(1-10) disperses throughout germ cell nuclei and cytoplasm. wrmScarlet(1-10) is also maternally loaded into embryos, where it persists through early and mid-embryonic development.

JK2505 C. elegans cyd-1(q626) II; him-5(e1490) V. Show Description
Temperature-sensitive allele of cyd-1. Phenotypically wild-type at 15C. At 25C, approximately one-third of q626 hermaphrodites were missing one distal tip cell (DTC) and approximately one-half of q626 males were missing the linker cell (LC). q626 also feminizes the XO gonad. q626 affects the production of SGP daughters in both sexes. There is also a maternal component since the mutant phenotype is almost fully penetrant in offspring of homozygous mothers, but less penetrant in offspring of heterozygous mothers.
