Microsatellite marker development for the threatened orchid Masdevallia solomonii (Orchidaceae).

Premise Of The Study: Microsatellite markers for Masdevallia solomonii were developed to serve as a tool in future population genetic studies of this threatened species from the Bolivian Yungas.

Methods And Results: Thirteen microsatellite primers were characterized by cloning an intersimple sequence repeat (ISSR) library. From these, 10 loci presented considerable variation in allele number (3-10), expected heterozygosity (0.
