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

G. P. Moraes, Benitez, L. C., Amaral, M. Ndo, Vighi, I. L., Auler, P. A., da Maia, L. C., Bianchi, V. J., and Braga, E. J. B., Evaluation of reference genes for RT-qPCR studies in the leaves of rice seedlings under salt stress, vol. 14, pp. 2384-2398, 2015.

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.

Application of denaturing gradient gel electrophoresis for detection of bacterial and yeast communities along a salinity gradient in the estuary of the Cachoeira River in Brazil

C. S. P. Rodrigues, Souza, S. S., Rezende, R. P., Silva, A., Andrioli, J. L., Costa, H., Fontana, R., and Dias, J. C. T., Application of denaturing gradient gel electrophoresis for detection of bacterial and yeast communities along a salinity gradient in the estuary of the Cachoeira River in Brazil, vol. 12, pp. 1752-1760, 2013.

An estuary is a transition zone between freshwater and marine ecosystems, resulting in dilution of seawater. Estuaries are also considered environments of intense biological activity related to the processes of nutrient cycling. The aim of this study was to evaluate the microbial community composition along a salinity gradient in the estuary of the Cachoeira River, located in southern Bahia, Brazil. The analysis of bacterial and yeast communities was performed by determining the denaturing gradient gel electrophoresis band richness.

Genetic analysis of NaCl tolerance in tomato

A. Saeed, Shahid, M. Q., Anjum, S. A., Khan, A. A., Shakeel, A., Saleem, M. F., and Saeed, N., Genetic analysis of NaCl tolerance in tomato, vol. 10, pp. 1754-1776, 2011.

We attempted to find the suitable parents for the development of tomato hybrids for high salt soils by exploiting combining ability, gene action and heterosis. Six salt-tolerant and three salt-intolerant genotypes, along with their 18 F1 crosses, were evaluated at seedling stage under 10 and 15 dS/m (NaCl) salinity stress, compared to the control level of salinity.
