Abstract
Microsatellites markers were developed for Paypayrola blanchetiana (Violaceae), a near-dispersing forest tree forming aggregated populations, to investigate genetic diversity and gene flow among subpopulations in a fragmented environment. Next generation sequencing (Illumina platform) was used to develop ten nuclear microsatellite loci and one plastid microsatellite locus that amplify in P. blanchetiana. Polymorphism was tested in two subpopulations separated by a distance of approximately 11km. The identified loci contained between two and five alleles per locus. Observed heterozygosity ranged between 0.063 and 0.563 in both subpopulations, while expected heterozygosity ranged from 0.063 to 0.567 in the first, and 0.063-0.627 in the second subpopulation. The microsatellites are among the first in the family Violaceae and will be useful for population genetic studies in this species. Amplification was successful in one further Paypayrola species from Amazonia, which suggest a wider usefulness of the present markers.
