Premise Of The Study:
Microsatellite primers were developed in the foundational tree species Pinus edulis to investigate population differentiation of P. edulis and hybridization among closely related species. •
Methods And Results:
Using a hybridization protocol, primer sets for 11 microsatellite loci were developed using megagametophyte tissue from P. edulis and scored for polymorphism in three populations of P. edulis and a single P. monophylla population. The primers amplified simple and compound di-, tri-, and pentanucleotide repeats with two to 18 alleles per locus. •
Conclusions:
These results demonstrate the utility of the described primers for studies of population differentiation within and among P. edulis populations as well as across putative hybrid zones where P. edulis may coexist with sister species.
