Genetically Modified Crops: Risks and Promise
Provedor de dados: 7
Autores: Conway, Gordon; The Rockefeller Foundation; president@rockfound.org.
GM foods have the potential to provide significant benefits for developing countries. Over 800 million people are chronically undernourished, and 180 million children are severely underweight for their age. By 2020, there will be an extra two billion mouths to feed. Ecological approaches that underpin sustainable agriculture (e.g., integrated pest management) and participatory approaches that strengthen farmers' own experimentation and decision making are key. Biotechnology will be an essential partner, if yield ceilings are to be raised, if crops are to be grown without excessive reliance on pesticides, and if farmers on less favored lands are to be provided with crops that are resistant to drought and salinity, and that can use nitrogen and other...

Alfalfa is one of the most frequently studied species from the production of tissue culture-derived embryos point of view. In this study, five alfalfa cultivars were analyzed with reference to their ability to regenerate plants from protoplast cultures via somatic embryogenesis. Plant regeneration from leaf-derived protoplasts isolated from the cultivar Rangelander was achieved using a protocol defined for alfalfa cell suspension-derived embryogenesis. Because of its high efficiency, this procedure is recommended for protoplast electroporation-mediated genetic transformation of alfalfa.

Effect of salinity stress in Setaria viridis (L.) P. Beauv. accession A10.1 during seed germination and plant development
Provedor de dados: 64

ABSTRACT Setaria viridis (L.) P. Beauv. is a species proposed to be used as model plant in reverse genetics studies for the validation of gene function. Soil salinity is a recurring problem present in more than a 100 countries worldwide, and approximately 20% of the agricultural land in the world has saline and/or sodium soils. Saline stress affects all the main processes of the plant, such as germination, growth, and, consequently, the yield. The present study aimed at determining the tolerance levels of S. viridisA10.1 to saline stress and identify its potential as a model plant to validate salt-tolerance candidate genes/alleles as well as promoter sequences from salt-responsive genes. In an initial experiment, the seeds of the plant were sown on a...
