Abstract

In recent years, the substitution of fossil fuels by alternative sources of energy has been intensely discussed. Great efforts have been focused on research of renewable fuels and ethanol emerges as a promissory solution for this subject. In this context, sugarcane appears in advantage in Brazil due to its high adaptability to different environmental conditions and its high productivity and yield in ethanol production. However, in order to respond the global increasing demand of energy ethanol production needs to be increased as well. Together with the idea of substitution of fossil fuels comes in focus the environmental issues and sustainability in our way of living. The increase in areas cultivated with sugarcane could, therefore, results in great environmental impacts, leading us to search alternatives to increase ethanol production. Thus, genetic engineering might contribute significantly to improve productivity, increasing ethanol production without expanding cultivated areas. This project propose the increase in sugar levels in sugarcane and in the model plant Brachypodium distachyon through transgenic technologies, focusing as strategies changes in redox status of the mitochondrial, which may lead to higher levels of sugars, and changes in the synthesis of other fermentable sugars, as a way to improve ethanol production by area. These strategies can result not only in transgenic events with agronomic potential, but would bring also important information about the relationship of cellular respiration and the use of carbon in sugarcane, bringing new insights of research in this area.
