The manuscript describes the isolation, identification, and characterization of a mutant (bar18) from a phenotypic screen for abnormal number of muscle nuclei. The authors mapped the mutant to the unc-83 gene, perform rescue experiments, and identify a potential interacting partner unc-84, which is supposed to act in a complex with unc-83. The manuscript is technically sound, all experiments are well designed and executed.
There is only one minor typographical error in the methods section:
The plasmid genotypes described for dBT599 and dBT573 are identical (see the first line of section "Generation of transgenic rescue lines"). This is most likely a copy-paste error, please make suitable corrections. With this change, the manuscript appears suitable for publication.
