[Advances in microbial synthesis of plant natural products].

Plant natural products are one of the main sources of small molecule drugs, nutraceuticals, cosmetics and fragrances, and play an important role in economy development. At present, the way of obtaining plant natural products mainly depends on direct extraction from plants, which is farm land occupying and time consuming. The contents of active ingredients in plants are usually low, and thus the production cost is high. By elucidating the biosynthetic pathways and reconstructing the pathways in microbial cells, plant natural products can be produced by fermentation using renewable raw materials. Microbial biosynthesis provides a new route for the supply of plant natural products. This review summarizes the research progress of microbial synthesis of terpenoids, flavonoids, phenylpropanoids and other important natural products of plants in Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences. Current research challenges and future prospects are also briefly discussed.
