METHODS AND COMPOSITIONS FOR ENHANCING PLANT STRESS TOLERANCE THROUGH GENETIC MODIFICATIONS

Abstract

The present invention provides methods and compositions for enhancing plant tolerance to environmental stresses, such as drought, salinity, extreme temperatures, and oxidative damage, through targeted genetic modifications. This invention involves identifying and modifying stress-responsive genes in plants using advanced gene-editing tools like CRISPR-Cas, RNA interference (RNAi), or traditional transformation techniques. Additionally, it includes novel recombinant DNA compositions, vectors, and stress-inducible promoters to enable precise control of gene expression in response to environmental triggers. By creating transgenic plants with improved resilience to multiple stress factors, this invention supports sustainable agriculture by enhancing crop productivity and stability in challenging growing conditions.
