odr-7 mutants fail to respond to odorants sensed by the AWA neurons.

slt-1 mutants have no dissecting-scope phenotype. They have a 40% penetrant defect in the ventral guidance of the AVM neuron scored with mec-4::GFP, a mild defect in CAN cell migration that is enhanced by a ceh-23::GFP transgene, and a mild defect in midline crossing by PVQ neurons scorable with sra-6::GFP. slt-1(eh15) is a complex rearrangement that duplicates the endogenous slt-1 gene, but disrupts both duplicated copies. The two copies are linked on X but the exact distance between them is not known. The duplication probably extends >13 kb based on Southern blotting. Deletion breakpoints for the first copy of slt-1 are as follows: nucleotides 26219 to 28163 and 28197 to 28294 in cosmid C26G2 are deleted. The second copy of slt-1 contains the following structure: nucleotides 28197 to 28294 in C26G2 are deleted, followed by a duplication of nucleotides 28300 to 28396 in C26G2 that begins 5 nucleotides after the deletion. Both copies of slt-1 are mutant, as confirmed by both DNA sequence and RT-PCR analysis of slt-1 mRNA. Scoring for homozygosity of the slt-1 allele by PCR is difficult because of the two copies of the gene and because the small deletion and the small duplication of the second copy of slt-1 are the same size. The mutant can be followed indirectly by X linkage (very closely linked to unc-3). It may be possible to make a specific primer within the duplicated region that detects a unique band in the slt-1 mutant.

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. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Don Riddle. mIn1 pka mC6.

Heterozygotes are WT and segregate WT, DpyUnc [mIn1(mc6) homozygotes], and two-fold arrest Let Rol progeny. Well balanced. Male stock. Cross WT males to WT hermaphrodites and check for correct segregation of progeny.

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.

Heterozygotes are WT and segregate WT, Lethal Rollers (arrested 2-fold hatchlings), and Unc-4 mIn1(mC6) homozygotes. Pick WT and check for correct segregation of progeny.

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].
