Microsatellites in Cetaceans: an Overview.
The Open Marine Biology Journal, 2008, 2, 38-42.
This paper presents a comprehensive overview of the published literature on
microsatellites studied in cetaceans from 1989 to 2007. We inventoried 246
loci isolated from 18 and amplified in 51 cetacean species representing 11
families. The majority of loci (68%) were dinucleotide (CA) repeats, which
were also shown to be on average more variable than tetranucleotide
repeats. For each of these loci and the 1610 locus/species combinations, we
present the species in which the markers were isolated and tested, specific
diversity parameters (number of alleles, expected and observed
heterozygosities), together with the primer sequences, the size range of
the PCR products and the GenBank accession number. Simple analyses were
performed on the assembled data and the widespread use of cross-species
amplification, an important source of microsatellites in cetaceans, is
discussed using laboratory data from Stenella coeruleoalba. No significant
ascertainment bias was detected when considering all dinucleotide or
tetranucleotide loci. This comprehensive database should help to inform
those working on population and conservation genetic studies in most
