Isolation and characterization of microsatellite loci in the icefish Chionodraco rastrospinosus (Perciformes, Notothenioidea, Channichthyidae)
Abstract We characterized eight polymorphic microsatellites in the icefish Chionodraco rastrospinosus (Perciformes, Notothenioidea, Channichthyidae). Microsatellites were isolated from a partial genomic library enriched for an AC motif. Chionodraco rastrospinosus is an endemic species inhabiting sou...
