yIs2 [xol-1::laxZ + rol-6(su1006)] IV. Rollers. XO-specific expression of lacZ fusion.

WT hermaphrodites whose progeny include WT hermaphrodites, Dpy hermaphrodites (mnDp66; unc-1 dpy-3), Unc hermaphrodites (yDp14; unc-1 dpy-3), DpyTra hermaphrodites (mnDp66/yDp14; yDf17), WT males, Unc males, and Dpy males. There are 2 types of WT hermaphrodites in this strain which are indistinguishable unless you score their offspring: mnDp66/yDp14; him-8; yDf17/unc-1 dpy-3 animals will have many WT males progeny; but mnDp66/yDp14; him-8; unc-1 dpy-3 animals will have primarily dpy male progeny [mnDp66/yDp14; unc-1 dpy-3 XO animals are mostly dead, but there are some escapers of lethality]. Maintain by picking L4 WT hermaphrodites and checking for correct segregation of progeny.

4xwrmScarlet11 tag inserted inserted at 5' end of rab-3b locus using CRISPR/Cas9. Insertion confirmed by sequencing. wrmScarlet11::RAB-3B shows smaller RAB-3 puncta compared to over-expression reporters. The fusion protein is likely non-functional as the strain shows strong aldicarb resistance; however, the localization pattern of 4×wrmScarlet::RAB-3 is similar to that of transgenically expressed RAB-3. 4×wrmScarlet11::rab-3b strain also labels rab-3a; it is possible that 4×wrmScarlet11 inserted in the middle of rab-3a isoform disrupts the functions of RAB-3 in neurotransmission.

leIs8 [unc-5::lacZ + rol-6(su1006)]. Rollers. B-galactosidase expression was observed in the spermathecaeand the three rectal epithelial cells. Staining in the rectal area first observed in L1 larvae whilst expression in the spermathecae appeared as the structure formed in L4 larvae. Variable staining was also seen throughout the uterus. In the mature gonad staining appeared to be in two sets of two toroidal epithelial cells Ut-1 and Ut-2. Staining was also observed in the large H shpaed Use cell which attaches the uterus to the seam cells and the four epithelial cells Ut-1 and Ut-2. The Uv cells did not appear to stain. Individual worms often just showed one component of this expression. In males the expression was observed to be displayed in all or part of the procodeum. plasmid name: pUL#38E12. plasmid backbone: pPD22.11. Partial Sau3A fragments cloned into BamH1 site of vector.

csEx436 [lpr-3 (fosmid WRM619dE09) + myo-2p::mCherry]. Pick mCherry+ animals to maintain. cs231 is a Crispr/Cas9-induced null allele of lpr-3: a 13 nucleotide deletion in exon 1 results in frameshift. Homozygous mutants are embryonic lethal, but are rescued by csEx436 containing lpr-3(+) fosmid WRM619dE09.
