Diallel and prediction (REML/BLUP) for yield components in intervarietal maize hybrids

Genetic improvement is essential to achieve increments in maize (Zea mays L.) grain yield components. It may be obtained through crosses, which enable to exploit the effects of intervarietal heterosis, allelic complementarity, as well as gene actions and effects. This study estimated the components of variance and genetic parameters (REML/BLUP) of an intervarietal d.. Read More»

Evaluation of reference genes for RT-qPCR studies in the leaves of rice seedlings under salt stress

    G.P. Moraes, L.C. Benitez, M.N. do Amaral, I.L. Vighi, P.A. Auler, L.C. da Maia, V.J. Bianchi and E.J.B. Braga

To obtain accurate and reliable results for the expression of genes of interest using quantitative real-time polymerase chain reaction (RT-qPCR) techniques, it is necessary to normalize the data by comparing them to constitutive genes that exhibit uniform expression levels under experimental conditions. In this study, the stability of expression was evaluated for the following ten candidate ref.. Read More»

Selection of candidate reference genes and validation for real-time PCR studies in rice plants exposed to low temperatures

    P.A. Auler, L.C. Benitez, M.N. do Amaral, I.L. Vighi, G.S. Rodrigues, L.C. da Maia and E.J.B. Braga

Rice is a cereal that presents a great ability to adapt to different soil and climate conditions. However, as it is a tropical crop with C3 metabolism, it performs better in warm temperatures with high solar radiation. Tolerance to stress caused by low temperatures is a highly complex process that involves various metabolic pathways and cellular compartments, result.. Read More»

Changes in gene expression and catalase activity in Oryza sativa L. under abiotic stress

    I.L. Vighi, L.C. Benitez, M.N. do Amaral, P.A. Auler, G.P. Moraes, G.S. Rodrigues, L.C. da Maia, L.S. Pinto and E.J.B. Braga

Different rice (Oryza sativa L.) genotypes were subjected to high salinity and low temperature (150 mM NaCl and 13°C, respectively) for 0, 6, 24, 48, or 72 h. We evaluated the simultaneous expression of the genes OsCATA, OsCATB, and OsCATC, correlated gene expression with enzyme activity, and verified the regulation of these genes through identification of cis-e..

Estimates of genetic parameters and genotypic values prediction in maize landrace populations by REML/BLUP procedure

Lung cancer is the leading cause of cancer death in men and the second leading cause of cancer death in women worldwide. Fascin-1 and laminin-5 were associated with the invasiveness and prognoses of several cancers. The expression and the serum levels of fascin-1 and laminin-5 in patients with non-small cell lung cancer (NSCLC) were analyzed in this study. The expre.. Read More»
