Authors: S.V. ?lvares-Carvalho, R. Silva-Mann, I.B. Gois, M.F.V. Melo, A.S. Oliveira, R.A. Ferreira and L.J. Gomes
The success of recovery programs on degraded areas is dependent on the genetic material to be used, which should present heterozygosity and genetic diversity in native and recovered populations. This study was carried out to evaluate the model efficiency to enable the recovery of a degraded area of the Lower São Francis.. Read More»

Genetic diversity of Desmanthus sp accessions using ISSR markers and morphological traits
Authors: J.C. Costa, G.G.M. Fracetto, F.J.C. Fracetto, M.V.F. Santos and M.A. Lira Junior
Desmanthus is a genus of forage legumes with high nutritional value, productive potential, and ability to obtain nitrogen in association with diazotrophic bacteria. The use of accurate techniques for genotype identification and characterization is essential for breeding programs. Morphological markers are widely used to know t.. Read More»

Evaluation of genetic diversity among soybean (Glycine max) genotypes using univariate and multivariate analysis
Authors: M.M. Oliveira, L.B. Sousa, M.C. Reis, E.G. Silva Junior, D.B.O. Cardoso, O.T. Hamawaki and A.P.O. Nogueira
The genetic diversity study has paramount importance in breeding programs; hence, it allows selection and choice of the parental genetic divergence, which have the agronomic traits desired by the breeder. This study aimed to characterize the genetic divergence between 24 soybean genotypes through their agronomic traits, using .. Read More»

Genetic variability of garlic accessions as revealed by agro-morphological traits evaluated under different environments
Authors: E.S.S. Hoogerheide, J.A. Azevedo Filho, R. Vencovsky, M.I. Zucchi, B.W. Zago and J.B. Pinheiro
The cultivated garlic (Allium sativum L.) displays a wide phenotypic diversity, which is derived from natural mutations and phenotypic plasticity, due to dependence on soil type, moisture, latitude, altitude and cultural practices, leading to a large number of cultivars. This study aimed to evaluate the genetic variability sho.. Read More»

Genetic control of inflorescence in common bean
Authors: S.R. Guilherme1, M.A.P. Ramalho1, A. de F.B. Abreu2 and L.A. Pereira1
The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyze.. Read More»

Polymorphic microsatellite markers for the rare and endangered cactus Uebelmannia pectinifera (Cactaceae) and its congeneric species
Authors: E.M. Moraes1, F.W. Cidade1, G.A.R. Silva1 and M.C. Machado2
The cactus genus Uebelmannia includes 3 narrow endemic species associated with rocky savanna habitats in eastern South America. Because of their rarity and illegal over-collection, all of these species are endangered. Taxonomic uncertainties resulting from dramatic local variation in morphology within Uebelmannia species preclude effective conservation ef.. Read More»

Genetic-molecular characterization of backcross generations for sexual conversion in papaya (Carica papaya L.)
Authors: H.C.C. Ramos1, M.G. Pereira1, T.N.S. Pereira1, G.B.A. Barros1 and G.A. Ferreguetti2
The low number of improved cultivars limits the expansion of the papaya crop, particularly because of the time required for the development of new varieties using classical procedures. Molecular techniques associated with conventional procedures accelerate this process and allow targeted improvements. Thus, we used microsatellite markers to perform geneti.. Read More»

Association between CYP1A1m1 gene polymorphism and primary open-angle glaucoma
Authors: N.B. Costa, C.T.X. Silva, A.B. Frare, R.E. Silva and K.K.V.O. Moura
The CYP1A1 gene is related to the generation of secondary metabolites that are capable of inducing DNA damage. The CYP1A1m1 polymorphism has been examined in many studies, and is located in a region near loci that have been linked to glaucoma, including the locus GLC1I. As a result, this polymorphism has been related to several diseases that are influence.. Read More»

Microsatellite in Aeschynomene falcata (Leguminosae): diversity, cross-amplification, and chromosome localization
Authors: C.A. Polido1,3, C.C. Mantello2, A.P. Moraes1,4, A.P. Souza1,2 and E.R. Forni-Martins1
Aeschynomene falcata is an important forage species; however, because of low seed production, it is underutilized as forage species. Aeschynomene is a polyphyletic genus with a challenging taxonomic position. Two subgenera have been proposed, and it is suggested that Aeschynomene can be split in 2 genera... Read More»
