Abstract

We examined cross-species transferability and usefulness of six nuclear microsatellite markers developed in consubgeneric eastern white pine (Pinus strobus) with regard to ecologically and commercially important Mexican white pine species of conservation genetics concern: Pinus chiapensis (Mart.) Andresen, P. flexilis James, P. strobiformis Engelm., P. ayacahuite Ehrenb. Ex Schltdl, and P. ayacahuite var. veitchii (Roezl) G.R. Shaw. Four to six microsatellite loci were found to be polymorphic in different species, with moderate to high informativeness in a relatively small number of samples (PIC/HE = 0.25-0.93). This successful transfer sidesteps the time- and resource-consuming development of species-specific microsatellite markers, and will facilitate population and conservation genetic studies and genetic resource management of the less studied Mexican white pines.
