Authors: J.C. Cabral, A.B. Baldoni, H. Tonini, V.C.R. Azevedo, L.D. Giustina, A.V. Tiago and A.A.B. Rossi
The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The em.. Read More»

Bayesian analyses of genetic parameters for growth traits in Nellore cattle raised on pasture
Authors: F.B. Lopes, J.L. Ferreira, R.B. Lobo and G.J.M. Rosa
This study was carried out to investigate (co)variance components and genetic parameters for growth traits in beef cattle using a multi-trait model by Bayesian methods. Genetic and residual (co)variances and parameters were estimated for weights at standard ages of 120 (W120), 210 (W210), 365 (W365), and 450 days (W450), and f.. Read More»

Selection of maize inbred lines and gene expression for resistance to ear rot
Authors: G.S. Pereira, R.G.V. Pinho, E.V.R.V. Pinho, L.P.M. Pires, L.A.Y. Bernardo Junior, J.L.A. Pereira and M.P. Melo
In recent years, there has been a large incidence of fungi causing “ear rot” in maize in Brazil, the main fungus being Fusarium verticillioides. The most efficient and competitive alternative for control of this disease consists of using maize hybrids resistant to this pathogen. Thus, the aims of this study were to.. Read More»

Variability among Capsicum baccatum accessions from Goi�¡s, Brazil, assessed by morphological traits and molecular markers
Authors: A.L.A. Martinez, J.S.P. Ara�ºjo, C.F. Ragassi, G.S.C. Buso and F.J.B. Reifschneider
Capsicum peppers are native to the Americas, with Brazil being a significant diversity center. Capsicum baccatum accessions at Instituto Federal (IF) Goiano represent a portion of the species genetic resources from central Brazil. We aimed to characterize a C. baccatum working collection comprising 27 accessions and 3 commerci.. Read More»

An optimized protocol for DNA extraction in plants with a high content of secondary metabolites, based on leaves of Mimosa tenuiflora (Willd.) Poir. (Leguminosae)
Authors: S.R. Arruda, D.G. Pereira, M.M. Silva-Castro, M.G. Brito and A.M. Waldschmidt
Some species are characterized by a high content of tannins, alkaloids, and phenols in their leaves. These secondary metabolites are released during DNA extraction and might hinder molecular studies based on PCR (polymerase chain reaction). To provide an efficient method to extract DNA, Mimosa tenuiflora, an important legumino.. Read More»

Identification of Colletotrichum isolates from Capsicum chinense in Amazon
Authors: C.V.S. de Oliveira, K.S. Matos, D.M.C. de Albuquerque, R.E. Hanada and G.F. da Silva
Chili pepper (Capsicum chinense) is a great economic important culture on the State of Amazonas, and it represents, approximately, a production of 1.9 thousand tons per year. It is one of the hosts of Colletotrichum genus in the North region of Brazil. The aim of the study was to differentiate and to identify isolates of Colle.. Read More»

Generic relationships among Molluginaceae inferred from a molecular phylogenetic analysis of the matK gene
Authors: M.A. Ali, J. Lee and F. Al-Hemaid
The family Molluginaceae (order Caryophyllales) is considered polyphyletic based on the photosynthetic pathway, C4 evolution, and phylogeny of the family. This inference was made based on photosynthetic, anatomical, and molecular datasets. The generic circumscription of this family has greatly been changed owing to the placeme.. Read More»

Genetic variability among elite popcorn lines based on molecular and morphoagronomic characteristics
Authors: J.F. dos Santos, C.A. Mangolin, M.F.P.S. Machado, C.A. Scapim, W. Giordani and L.S.A. Gon�§alves
Knowledge of genetic diversity among genotypes and relationships among elite lines is of great importance for the development of breeding programs. Therefore, the objective of this study was to evaluate genetic variability based on the morphoagronomic and molecular characterization of 18 elite popcorn (Zea mays var. everta) li.. Read More»

Genetic correlation and genome-wide association study (GWAS) of the length of productive life, days open, and 305-days milk yield in crossbred Holstein dairy cattle
Authors: P. Saowaphak, M. Duangjinda, S. Plaengkaeo, R. Suwannasing and W. Boonkum
In this study, we estimated the genetic parameters and identified the putative quantitative trait loci (QTL) associated with the length of productive life (LPL), days open (DO), and 305-day milk yield for the first lactation (FM305) of crossbred Holstein dairy cattle. Data comprising 4,739 records collected between 1986 and 20.. Read More»

The Staphylococcus aureus is the most common isolated microorganism in ruminant animal species diagnostic with clinical or subclinical mastitis. Dairy herds with these diseases can transfer S. aureus into the milk supply, which can lead to food poisoning in humans. The objective of this study was to evaluate the profile of ant.. Read More»
