Brazil is considered one of the domestication centers of cassava (Manihot esculenta), containing a large part of the biological diversity and traditional knowledge of the species. The aim of the present study was to evaluate the genetic diversity of cassava landraces grown by farmers in the north of Mato Grosso State, Brazil, using inter simple sequence repeat (ISSR) molecular markers. The study was carried out in the municipality of Alta Floresta, MT, on farms located in two rural areas. Seventeen cassava landraces were selected.

Genetic diversity of the Neotropical tree Hancornia speciosa Gomes in natural populations in Northeastern Brazil

H. J. Jimenez, Martins, L. S. S., Montarroyos, A. V. V., Junior, J. F. Silva, Alzate-Marin, A. L., and Filho, R. M. Moraes, Genetic diversity of the Neotropical tree Hancornia speciosa Gomes in natural populations in Northeastern Brazil, vol. 14, pp. 17749-17757, 2015.

Mangabeira (Hancornia speciosa Gomes) is a fruit tree of the Apocynaceae family, which is native to Brazil and is a very important food resource for human populations in its areas of occurrence. Mangabeira fruit is collected as an extractive activity, and no domesticated varieties or breeding programs exist. Due to a reduction in the area of ecosystems where it occurs, mangabeira is threatened by genetic erosion in Brazil.

Comparison of eight methods of genomic DNA extraction from babassu

J. P. G. Viana, Borges, A. N. C., Lopes, A. C. A., Gomes, R. L. F., Britto, F. B., Lima, P. S. C., and Valente, S. E. S., Comparison of eight methods of genomic DNA extraction from babassu, vol. 14, pp. 18003-18008, 2015.

Babassu (Orbignya phalerata Martius) is one of the most important palms in Brazil because of the largest morphological variation, wide geographic distribution, and high socio-economic importance. The diversity present in babassu germplasm should be protected against loss to ensure their use with high productivity. Study of the available variability in populations of babassu is necessary to develop conservation strategies.
