Expectation for sustainable production of anticancer substances from a viewpoint of how genome evolves to be responsible for plant alkaloid biosynthesis
A research team of Chiba University, RIKEN CSRS, Kazusa DNA Research Institute, and National Institute of Genetics revealed a highly accurate whole genome sequence at the chromosome level for Ophiorrhiza pumila, a medicinal resource plant which produces camptothecin used as an anticancer drug. The group also made a comparison with the genome of other plants and revealed how the capacity has evolved to produce camptothecin and related compounds.
The study results may resolve a fundamental question on how a certain plant has acquired an ability to produce a medicinal product, and contribute to sustainable production of the active ingredient of the anti-cancer drug (camptothecin) in the future.
