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..

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»

Genetic diversity of Saccharum complex using ISSR markers
Authors: L.A.R. Oliveira, C.A. Machado, M.N. Cardoso, A.C.A. Oliveira, A.L. Amaral, A.R.C. Rabbani, A.V.C. Silva and A.S. Ledo
Sugarcane (Saccharum sp, Poaceae) is native to Southeast Asia, and due to growing demand as raw material, its cultivation recently expanded to new frontiers. The genetic diversity analysis is essential for targeting strategies in the formation and maintenance of a germplasm. This study aimed to assess the genetic diversity of .. Read More»

Genetic diversity of Plathymenia reticulata Benth. in fragments of Atlantic Forest in southeastern Brazil
Authors: L.C. Souza, A.L. Silva J�ºnior, M.C. Souza, S.H. Kunz and F.D. Miranda
Studies of genetic diversity in natural populations are important for the definition of conservation strategies, especially in populations reduced by processes of fragmentation and continuous forest extraction. Molecular markers stand out as interesting tools for these studies. The objective of this research was to characteriz.. Read More»

Analysis of genetic variability of commercial melon cultivars using SSR molecular markers
Authors: N. Carvalho, F.M. Canela, P.H.S. Leite, M.A. Ferreira, V.R. Oliveira, M.F. Santos, N.O.S. Souza and G.S.C. Buso
Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively nar.. Read More»
