Microsatellite primers for an Amazonian lowland tropical tree, Protium subserratum (Burseraceae)

• Premise of the study: The first microsatellite primers were developed for Protium subserratum , a widespread Amazonian tree, to investigate genetic differentiation between populations found on clay, brown‐sand, and white‐sand soils. • Methods and Results: Seventeen primer pairs were identified from two individuals of P. subserratum found on white‐sand and brown‐sand soil types. Polymorphism was analyzed in 63 individuals from a total of three populations, each found on a different soil type. The primers amplified tetra‐, tri‐, and dinucleotide repeats with three to 24 alleles per locus. Excluding monomorphic loci, observed and expected heterozygosities ranged from 0 to 0.852 and 0.036 to 0.901, respectively. • Conclusions: These new microsatellite markers will be useful in studies of genetic diversity, population differentiation, and gene flow across habitat types in P. subserratum .
