Advances in heterologous biosynthesis of plant and fungal natural products by modular co-culture engineering.

Heterologous biosynthesis has been long pursued as a viable approach for high efficiency production of natural products with various industrial values. Conventional methods for heterologous biosynthesis use the mono-culture of an engineered microbe for accommodating the whole target biosynthetic pathway to produce the desired product. The emergence of modular co-culture engineering, which divides the pathway between multiple co-culture strains, presents a new perspective to conduct heterologous biosynthesis and improve the bioproduction performance of natural products. This review highlights recent advances in utilizing the modular co-culture engineering approaches to address the challenges of plant and fungal natural product biosynthesis. Potential directions for future research in this promising field are also discussed.
