Abstract

[Abstract:] We report the characterization of three satellite DNAs in four species of mussel: Mytilus edulis, Mytilus galloprovincialis, Mytilus trossulus, and Mytilus californianus. The monomers of the Apa I satellite DNAs were 173, 161, and 166 bp long. These satellite monomers were used to construct phylogenetic trees to infer relationships among these species. The topologies obtained clearly indicate that M. californianus is the most divergent species with respect to the other three. Furthermore, localization of satellite DNAs on metaphase chromosomes was performed using fluorescent in situ hybridization (FISH). Fluorescent signals revealed a different organization and distribution of these three satellite DNAs.
