The field of metabolic engineering in plants has made significant strides in recent years, offering promising solutions to global challenges in agriculture, nutrition, and sustainability. This review has highlighted the diverse strategies and applications of metabolic engineering, from enhancing photosynthetic efficiency and nutrient use to improving stress tolerance and producing valuable metabolites. The integration of advanced technologies, including CRISPR/Cas9 gene editing, synthetic biology approaches, and multi-omics data analysis, has dramatically expanded our ability to manipulate plant metabolism with unprecedented precision. These tools have enabled researchers to create crops with improved yield, nutritional quality, and resilience to environmental stresses, potentially revolutionizing agricultural practices in the face of climate change and population growth.
