Genetic diversity and structure in natural populations of Maytenus truncata Reiss, 1861, a medicinal plant vulnerable to extractivism in Bahia State, Brazil

R. R. Simplicio, Waldschmidt, A. M., Amorim, M. B., Almeida, B. S., and Pereira, D. G., Genetic diversity and structure in natural populations of Maytenus truncata Reiss, 1861, a medicinal plant vulnerable to extractivism in Bahia State, Brazil, vol. 14, pp. 18241-18248, 2015.

Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and population structure of M. truncata based on inter simple sequence repeat (ISSR) molecular markers.

Population structure and genetic diversity in Gynaikothrips uzeli (Thysanoptera: Phlaeothripidae): is there a correlation between genetic and geographic proximity?

A. L. S. Mascarenhas, Waldschmidt, A. M., and Silva, Jr., J. C., Population structure and genetic diversity in Gynaikothrips uzeli (Thysanoptera: Phlaeothripidae): is there a correlation between genetic and geographic proximity?, vol. 14, pp. 9793-9803, 2015.

Gynaikothrips uzeli (Thysanoptera: Phlaeothripidae) is a minuscule insect species, which forms galls, is subsocial, and parthenogenetic. It is associated with Ficus benjamina L. (Moraceae) and has a pantropical occurrence. The paucity of genetic studies on the order Thysanoptera led us to use inter-simple sequence repeat molecular marker to assess intra- and inter-gall, as well as intra- and inter-site, genetic variability and population structure of G. uzeli.
