ABSTRACT
Major hurdles in plant biosynthetic pathway elucidation and engineering include the need for rapid testing of enzyme candidates and the lack of complex substrates that are often not accumulated in the plant, amenable to synthesis, or commercially available. Linking metabolic engineering with gene discovery in both yeast and plant holds great promise to expedite the elucidation process and, at the same time, provide a platform for the sustainable production of plant metabolites. In this review, we highlight how synthetic biology and metabolic engineering alleviated longstanding obstacles in plant pathway elucidation. Recent advances in developing these chassis that showcase established and emerging strategies in accelerating biosynthetic gene discovery will also be discussed.
