Authors: N. Marini, C.B. Bevilacqua, M.V. B�¼ttow, M.C.B. Raseira and S. Bonow
Selecting and validating reference genes are the first steps in studying gene expression by reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR). The present study aimed to evaluate the stability of five reference genes for the purpose of normalization when studying gene expression in various cultivars of Pru.. Read More»

Assessment of allelic diversity among drought-resistant cotton genotypes using microsatellite markers
Authors: A. Javaid, F.S. Awan, F.M. Azhar and I.A. Khan
Drought, in conjunction with high temperature, is an important environmental constraint to cotton production. Development of cotton varieties with increased tolerance against adverse environmental conditions has been proposed as effective strategy for ensuring reliable yields. In the present study, 30 simple sequence repeat (S.. Read More»

Genetic divergence among corn hybrids and combining ability for agronomic and bromatological traits of silage
Authors: E. Gralak, M.V. Faria, A.S.T. Figueiredo, D.A. Rizzardi, M. Neumann, M.C. Mendes, C.A. Scapim and S. Galbeiro
We assessed the impact of genetic divergence and the ability to combine corn hybrids used for the production of silage on the agronomic and bromatological traits of silage quality. We evaluated 18 corn hybrids used as genitors in a circulant diallel scheme in which each genitor hybrid participated in 9 hybrid combinations, and.. Read More»

Analysis of protein profile of tomato root infected with Fusarium oxysporum f. sp lycopersici
Authors: T.D. Silva, C.M.A. Almeida, C.B. Malafaia, L.M.S. Oliveira, M.V. Silva and M.T.S. Correia
Fusarium wilt caused by Fusarium oxysporum f. sp lycopersici (Fol) is one of the main diseases affecting tomatoes. The BHRS 2,3 genotype of tomato is, however, resistant to this disease. A proteomic approach was used to understand the defense mechanisms of this genotype using the tomato root, the first tissue that interacts wi.. Read More»

Minimum number of measurements for evaluating soursop (Annona muricata L.) yield
Authors: C.F.B. S�¡nchez, P.E. Teodoro, S. Londo�±o, L.A. Silva, L.A. Peixoto and L.L. Bhering
Repeatability studies on fruit species are of great importance to identify the minimum number of measurements necessary to accurately select superior genotypes. This study aimed to identify the most efficient method to estimate the repeatability coefficient (r) and predict the minimum number of measurements needed for a more a.. Read More»

Cross-amplification and characterization of microsatellite markers in Alcantarea patriae Versieux & Wand.
Authors: A.G. Pereira, U.C.S. Bernardi, V.C. Manh�£es, R.S. Ferreira and F.D. Miranda
The Alcantarea patriae is a Bromeliaceae endemic to the inselbergs of the Atlantic Forest. This taxon, described in the year of 2007 by Versieux & Wanderley, presents restricted and fragmented distribution outside conservation units. Studies to evaluate the genetic structure of its populations can contribute to the conserv.. Read More»

High genetic diversity of Jatropha curcas assessed by ISSR
Authors: B.G. DÃ?Âaz, D.M. Argollo, M.C. Franco, S.M. Nucci, W.J. Siqueira, D.M. de Laat and C.A. Colombo
Jatropha curcas L. is a highly promising oilseed for sustainable production of biofuels and bio-kerosene due to its high oil content and excellent quality. However, it is a perennial and incipiently domesticated species with none stable cultivar created until now despite genetic breeding programs in progress in several countri.. Read More»

Expressed sequence tags related to nitrogen metabolism in maize inoculated with Azospirillum brasilense
Authors: L. Pereira-Defilippi, E.M. Pereira, F.M. Silva and G.V. Moro
The relative quantitative real-time expression of two expressed sequence tags (ESTs) codifying for key enzymes in nitrogen metabolism in maize, nitrate reductase (ZmNR), and glutamine synthetase (ZmGln1-3) was performed for genotypes inoculated with Azospirillum brasilense. Two commercial single-cross hybrids (AG7098 and 2B707.. Read More»

Influence of processing and storage of integral grape juice (Vitis labrusca L.) on its physical and chemical characteristics, cytotoxicity, and mutagenicity in vitro
Authors: E. D�¼sman, I.V. Almeida, E.P. Pinto, L. Lucchetta and V.E.P. Vicentini
Integral grape juice is extracted from the grape through processes that allow the retention of their natural composition. However, due to the severity of some processes, fruit juices can undergo changes in their quality. The present study evaluated the cytotoxic and mutagenic effects of integral grape juice by a cytokinesis-bl.. Read More»
