Isolation and characterization of polymorphic microsatellite loci from Wilsonia backhousei (Convolvulaceae)

摘要

Wilsonia backhousei is a clonal saltmarsh plant restricted to the southern latitudes of Australasia and threatened in New South Wales. We have identified eight informative microsatellite loci in the species from (AG)(n)- and (AC)(n)-enriched libraries. In 48 samples from two populations we detected an average of five alleles per locus (range 2-8, average H-E = 0.45), of which 72% were unique to one population or the other. Six of the eight loci were also amplifiable in Wilsonia rotundifolia under the same reaction conditions. The markers will be excellent tools for use in the management and conservation of both species.
