Recent studies in invertebrates have provided important mechanistic insights into several general aspects of muscle development. Two new genes have been identified that are involved in muscle fusion in Drosophila and a novel maternal component was shown to be responsible for myogenic determination in an ascidian. In addition, genetic analyses of nematode and Drosophila homologues of factors known to be myogenic regulators in other species yielded surprising findings about both the evolutionary conservation and divergence of these functions. Drosophila myogenesis has become a highly informative model for understanding the interplay between the signaling and transcriptional networks that underlie cell-fate specification during embryonic development.
