ISSR markers in wild species of Passiflora L. (Passifloraceae) as a tool for taxon selection in ornamental breeding
Authors: A.G.R. Sousa, M.M. Souza, C.A.F. Melo and G.A. Sodr?©
Inter simple sequence repeat (ISSR) molecular markers were developed and used to investigate interspecific genetic variation in 25 wild species of Passiflora preserved in an active germplasm bank (BAG-Passifloras); intraspecific diversity was also analyzed in P. cincinnata accessions. Of 31 primers tested, 20 identified polymorphic loci with a total of 33.. Read More»

Polymorphisms in the GHRL gene and their associations with traits of economic interest in beef cattle
Authors: C.U. Braz, G.M.F. Camargo, D.F. Cardoso, F.M.M. Gil, P.D.S. Fonseca, J.N.S.G. Cyrillo, M.E.Z. Mercadante, H.N. Oliveira and H. Tonhati
The hormone ghrelin is produced in the stomach wall, has an orexigenic function, stimulates growth hormone secretion, and affects the energy balance of the animal. Therefore, the ghrelin gene (GHRL) is considered to be a good candidate marker for the identification of traits of great economic importance in cattle, such as those associated with feed intake..

Populations of Erythrina velutina Willd. at risk of extinction
Authors: M.F.V. Melo, L.O. Gon?§alves, A.R.C. Rabbani, S.V. ?lvares-Carvalho, J.B. Pinheiro, M.I. Zucchi and R. Silva-Mann
The goal of this study was to characterize the structure of two natural populations of the coral tree using RAPD and ISSR markers. The study evaluated all individuals in two different areas in the northeastern region of Brazil: the first was in the riparian area, 10 km x 100 m along the edge of the lower São Francisco River, and the second was in t..

A priori choice of hybrid parents in plants
Authors: Luiz Ant?´nio dos Santos Dias, Edgard Augusto de Toledo Picoli, Rodrigo Barros Rocha and Acelino Couto Alfenas
Plant breeding deals with high-yielding genotypes. However, how best to choose parents of these genotypes remains an unsolved question. Here, we focus on a priori choice based on parental distances by means of agronomic and molecular data. Despite numerous theoretical and empirical studies, a priori choice continues to be a co..
