Abstract

Metabolic engineering in plants has emerged as a powerful approach to address global challenges in agriculture, nutrition, and sustainability. This comprehensive review explores cutting-edge strategies for manipulating primary and secondary metabolic pathways in plants, utilizing advanced genetic modification tools to enhance crop yield, nutritional quality, stress tolerance, and the production of valuable metabolites. We examine recent successes in improving photosynthetic efficiency, nutrient use, and abiotic stress resistance through targeted metabolic interventions. The review also delves into emerging trends, such as synthetic biology approaches and multi-gene trait stacking, which are revolutionizing the field. By integrating omics technologies, including genomics, transcriptomics, proteomics, and metabolomics, with advanced computational modeling, researchers are optimizing metabolic engineering designs with unprecedented precision. We discuss the application of CRISPR/Cas9 and other gene editing techniques in refining plant metabolism, as well as the potential of plants as biofactories for pharmaceutical and industrial compounds. As the field rapidly evolves, we consider the regulatory and biosafety aspects of genetically modified crops, providing insights into the future of sustainable agriculture and crop improvement. This review highlights the transformative potential of plant metabolic engineering in addressing food security, climate change adaptation, and the sustainable production of valuable compounds, while also discussing the challenges and future perspectives of this dynamic field.
