Abstract

The study of the stress response mechanisms in sugarcane can contribute to the creation of varieties more resistant to cold and drought. This project aims to characterize the role of the SsNAC23 gene, induced by cold temperatures and with high similarity to transcription factors. To this end, the responses will be studied of plants superexpressing or silenced for the SsNAC23 gene. Analyses of the photosynthesis, levels of prolene and lipid peroxidation will be conducted in the transgenic plants and in control plants, subjected or not to conditions of cold and hydric stress, so as to verify the greatest resistance of transgenic plants to these conditions. The genes regulated by the SsNAC23 factor of transcription will be identified via microarrays of cDNA, comparing control and transgenic plants. (AU)
