W., Genetic diversity analysis of Croton antisyphiliticus Mart. using AFLP molecular markers, vol. 15, p. -, 2016.

Croton antisyphiliticus Mart. is a medicinal plant native to Cerrado vegetation in Brazil, and it is popularly used to treat urogenital tract infections. The objective of the present study was to assess the genetic variability of natural C. antisyphiliticus populations using AFLP molecular markers. Accessions were collected in the states of Minas Gerais, São Paulo, and Goiás. The genotyping of individuals was performed using a LI-COR® DNA Analyzer 4300. The variability within populations was found to be greater than the variability between them.

Exhaustive search for conservation networks of populations representing genetic diversity

C., Exhaustive search for conservation networks of populations representing genetic diversity, vol. 15, p. -, 2016.

Conservation strategies routinely use optimization methods to identify the smallest number of units required to represent a set of features that need to be conserved, including biomes, species, and populations. In this study, we provide R scripts to facilitate exhaustive search for solutions that represent all of the alleles in networks with the smallest possible number of populations.

Intraspecific differentiation of Hancornia speciosa revealed by simple sequence repeat and random amplified polymorphic DNA markers

C. A. Nogueira, Stafuzza, N. B., Ribeiro, T. P., Prado, A. D. L., Menezes, I. P. P., Peixoto, N., Gonçalves, P. J., and Almeida, L. M., Intraspecific differentiation of Hancornia speciosa revealed by simple sequence repeat and random amplified polymorphic DNA markers, vol. 14, pp. 15996-16005, 2015.

Hancornia speciosa, popularly known as mangabeira, is a fruit tree native to the Brazilian Cerrado that shows great economic potential, due to its multiple uses. Intraspecific classification of this species is difficult because it shows high morphological diversity. An early study of the species reported that there are six botanic varieties that differ morphologically mainly in the shapes of their leaves and flowers.

Development of microsatellite markers for Hancornia speciosa Gomes (Apocynaceae)

A. J. L. Rodrigues, Yamaguishi, A. T., Chaves, L. J., Coelho, A. S. G., Lima, J. S., and Telles, M. P. C., Development of microsatellite markers for Hancornia speciosa Gomes (Apocynaceae), vol. 14, pp. 7274-7278, 2015.

Herein, we describe 34 microsatellite loci developed using an enrichment genomic library for the tree species Hancornia speciosa Gomes (Apocynaceae). Thirty-five individuals were genotyped using 34 primers to analyze the polymorphisms at each locus. The number of alleles per locus ranged from 4 to 20. The average number of alleles was 8.11, and the expected heterozygosity ranged from 0.62 to 0.94. These microsatellite primers will be useful in population genetics studies for this species.
