Biosynthesis and regulation of terpenoid indole alkaloids in Catharanthus roseus.

Catharanthus roseus produces a wide range of terpenoid indole alkaloids (TIA). Many of them, such as vinblastine and vincristine, have significant bioactivity. They are valuable chemotherapy drugs used in combination with other drugs to treat lymphoma and leukemia. The TIA biosynthetic pathway has been investigated for many years, for scientific interest and for their potential in manufacturing applications, to fulfill the market demand. In this review, the progress and perspective of C. roseus TIA biosynthesis and its regulating enzymes are described. In addition, the culture condition, hormones, signaling molecules, precursor feeding on the accumulation of TIA, and gene expression are also evaluated and discussed.
