A VISIBLE ALLELE OF THE MUSCLE GENE sup-10 X OF C. ELEGANS

In this paper, we extend our previous analyses of a set of genes in Caenorhabditis elegans that are involved in muscle structure and function: unc-93 III, sup-9 II, sup-10 X and sup-11 I. We describe an unusual, visible allele of sup-10, examine how this allele interacts genetically with mutations in other genes of this set and propose that the wild-type products of the unc-93 and sup-10 loci may be components of a protein complex. We also describe a new gene of this set, sup-18 III, and the interaction of sup-18 alleles with mutations in the other genes.
