Premise of the study: Microsatellite primers were developed for the tree species Genipa americana (Rubiaceae) for further population genetic studies.Methods and Results: We identified 144 clones containing 65 repeat motifs from a genomic library enriched for (CT)(8) and (GT)(8) motifs. Primer pairs were developed for 32 microsatellite loci and validated in 40 individuals of two natural G. americana populations. Seventeen loci were polymorphic, revealing from three to seven alleles per locus. The observed and expected heterozygosities ranged from 0.24 to 1.00 and from 0.22 to 0.78, respectively.Conclusions: The 17 primers identified as polymorphic loci are suitable to study the genetic diversity and structure, mating system, and gene flow in G. americana
