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 diversity in the germplasm of tropical maize landraces determined using molecular markers
Authors: D. Molin C.J. Coelho D.S. M�¡ximo F.S. Ferreira J.R. Gardingo R.R. Matiello
Maize landraces derived from tropical germplasm represent an important source of genetic variability, which is currently poorly understood and under-exploited by Brazilian crop breeding programs. The aims of our study were to a) estimate the genetic diversity across 48 varieties of maize landraces cultivated at different locations in the States of Rio Grande.. Read More»

Molecular analysis of genetic diversity among vine accessions using DNA markers
Authors: A.F. da Costa, P.E. Teodoro, L.L. Bhering, F.D. Tardin, R.F. Daher, W.F. Campos, A.P. Viana and M.G. Pereira
Viticulture presents a number of economic and social advantages, such as increasing employment levels and fixing the labor force in rural areas. With the aim of initiating a program of genetic improvement in grapevine from the State University of the state of Rio de Janeiro North Darcy Ribeiro, genetic diversity between 40 gen.. Read More»

Identification of Glomerella cingulata f. sp phaseoli recombinants by RAPD markers
Authors: O.A. Camargo Junior, E.A. Souza, M.C. Mendes-Costa, J.B. Santos, M.A. Soares
We examined the capacity of strains of Glomerella cin-gulata f. sp phaseoli fungus (Colletotrichum lindemuthianum sexual stage) to form recombinants, using random amplified polymorphic DNA (RAPD). Crosses of all possible combinations between strains 40, 42, 20, 21, 22, 23, 24, 25, and 26 were made on Petri dishes using M3 cult.. Read More»

Screening and identification of cucumber germplasm and rootstock resistance against the root-knot nematode (Meloidogyne incognita)
Authors: X.Z. Li and S.X. Chen
Root-knot nematodes (Meloidogyne spp) are destructive agricultural pests that reduce the productivity of cultivated vegetables worldwide, especially when vegetables are cropped continuously in greenhouses. Cucumbers (Cucumis sativus L.), in particular, suffer extensive damage due to root-knot nematodes, and only a few wild spe.. Read More»

Expression analysis of self-incompatibility-associated genes in non-heading Chinese cabbage
Authors: L. Wang, C. Wang, T.T. Ge, J.J. Wang, T.K. Liu, X.L. Hou and Y. Li
In Brassicaceae, a self-incompatibility (SI) system mediates pollen-pistil interactions. Self-pollen could be recognized and rejected by incompatible pistils. Several components involved in the SI response have been determined, including S-locus receptor kinase (SRK), S-locus cysteine-rich protein/S-locus protein 11, and arm r.. Read More»

Application of MUTIC to the exploration of gene expression data in prostate cancer
Authors: Goertzel B, Pennachin C, Coelho LS and Mudado MA
We show here an example of the application of a novel method, MUTIC (model utilization-based clustering), used for identifying complex interactions between genes or gene categories based on gene expression data. The method deals with binary categorical data which consist of a set of gene expression profiles divided into two bi.. Read More»

Function Clustering Self-Organization Maps (FCSOMs) for mining differentially expressed genes in Drosophila and its correlation with the growth medium
Authors: L.L. Liu, M.J. Liu and M. Ma
The central task of this study was to mine the gene-to-medium relationship. Adequate knowledge of this relationship could potentially improve the accuracy of differentially expressed gene mining. One of the approaches to differentially expressed gene mining uses conventional clustering algorithms to identify the gene-to-medium relationship. Compared to co.. Read More»

Clustering of soybean genotypes via Ward-MLM and ANNs associated with mixed models
Authors: P.E. Teodoro, F.E. Torres and A.M. Corr�ªa
The objectives of this study were to use mixed models to confirm the presence of genetic variability in 16 soybean genotypes, to compare clusters generated by artificial neural networks (ANNs) with those created by the Ward modified location model (MLM) technique, and to indicate parental combinations that hold promise for obtaining superior segregating p..
