Abstract: Seven polymorphic microsatellite markers were developed and validated for Bertholletia excelsa (Brazil nut tree) population genetic studies. This species is a widespread monotypic Amazonian tree with high non-timber economic value. Unfortunately, Brazil nut production is currently less than 25% of historical production levels, because of extensive deforestation. All pairs of primers produced clearly interpretable and polymorphic bands. No linkage disequilibrium was observed in an analysis of 46 individuals from one population, three to seven alleles per locus were observed; the expected heterozygosity ranged from 0.378 to 0.978, with significant heterozygote excess for four loci. An analysis of individuals from two populations showed private alleles at all loci. These primer pairs will be useful for population studies, especially for comparing samples from different parts of the Amazon forest.
