The use of plants for the production of industrial precursors and biomaterials represents another exciting application of metabolic engineering. Researchers have engineered plants to produce various polymers, including biodegradable plastics like polyhydroxyalkanoates (PHAs). The production of novel biomaterials in plants offers a renewable and potentially more environmentally friendly alternative to petroleum-based products . Additionally, plants are being engineered to produce precursors for various industrial applications, such as specialty fatty acids and biofuels, leveraging the plant's ability to harness solar energy for carbon fixation .
