|CB5414||C. elegans||srd-1(eh1) II. Show Description
EMS-induced deletion from -583 to +1017, including first two exons and part of third exon. Probable null. No obvious phenotype.
|CX5000||C. elegans||slt-1(eh15) X. Show Description
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.

|TL24||C. elegans||zdIs5 I; clr-1(cy14) II; slt-1(eh15) X. Show Description
zdIs5 [mec-4::GFP + lin-15(+)]. cy14 was isolated in a screen for suppressors of the AVM axon ventral guidance defect of slt-1 null mutant. cy14 is a G-to-A transition in the splice acceptor of intron 5 of clr-1 that leads to the use of a cryptic splice acceptor and consequently to an 18 bp deletion in exon 6.
