Genetic Polymorphism in Endometriosis: Trends in Scientific Production
Authors: Maria Gabriela Machado Junqueira, Amanda Fernandes Costa, Felipe de Ara�ºjo Nascimento, K�¡tia Karina Verolli de Oliveira Moura, Fl�¡via Melo Rodrigues
Endometriosis is characterized by the presence of endometrial tissue located outside the uterine cavity. The prevalence is around 6 to 10%. Regarding etiopathogenesis, several theories are accepted, but alterations in the molecular biology of the endometrium seem to be fundamental for the development of endometriosis. Women wi..

Estimate of natural cross-pollination rate of Capsicum annuum using a codominant molecular marker associated with fruit pungency
Authors: EV Justino, MEN Fonseca, ME Ferreira, LS Boiteux, PP Silva, WM Nascimento
The production of seeds with high genetic quality requires accurate estimates of the natural cross-pollination rate in cultivated Capsicum species. This is important in order to establish the most suitable isolation distance among fields of distinct genotypes, to minimize the risk of genetic contamination and to ensure that th.. Read More»

Genetic diversity in natural populations of Stylosanthes scabra using ISSR markers
Authors: J.C. Costa, G.G.M. Fracetto, F.J.C. Fracetto, T.C. Souza, M.V.F, Santos and M.A. Lira J�ºnior
Genetic diversity is the basis for genetic improvement, providing genes for new cultivars. Stylosanthes scabra is a legume used in pastures, presenting economic importance in tropical and subtropical regions. Molecular markers are targeted in population studies, thus we evaluated the genetic diversity distribution of S. scabra.. Read More»

Anthropization as a determinant factor in the genetic structure of Copernicia prunifera (Arecaceae)
Authors: L.G. Pinheiro, K.P.T. Chagas, A.S.M. Freire, M.C. Ferreira,C.G. Fajardo and F.A. Vieira
This study uses ISSR molecular markers to characterize the demographic pattern, and spatial genetic structure (SGS) at different life stages of development (cohorts) in a natural population of Copernicia prunifera in the Rio Grande do Norte State, Brazil. All individuals were sampled and georeferenced in a 0.55-ha plot. The de.. Read More»
