Medicinal Plants
Many of the herbs traditional healers have relied on for centuries — things like licorice and clover — produce these compounds naturally, but in such small amounts that pharmaceutical interest has long outpaced what growers could supply; this research opens a path to making them sustainably without stripping wild populations.
Certain plants make remarkable chemical compounds that show real promise against cancer, inflammation, and diabetes, but plants produce only tiny amounts of them and extracting them is complicated. Researchers have now figured out which plant genes and enzymes are responsible for building these compounds, and how the plant turns production on and off. Using that knowledge — plus tools like AI and genetic engineering of yeast or bacteria — scientists aim to brew these compounds in fermentation tanks instead of depending on limited wild plant sources.
Key Findings
Three families of enzymes — beta-amyrin synthases, cytochrome P450s, and UDP-glycosyltransferases — were identified as the key molecular assembly line for building these compounds inside plant cells.
MicroRNAs were found to act as an additional, previously underappreciated layer of regulation controlling how much of these compounds a plant produces, adding complexity beyond simple gene on/off switches.
Integrating AI and machine learning into pathway engineering is shifting the field from slow trial-and-error lab work toward predictive design, accelerating discovery of new biosynthetic gene clusters and enzyme improvements for high-yield production.

Liquorice or licorice is the common name of Glycyrrhiza glabra, a flowering plant of the bean family Fabaceae, from the root of which a sweet, aromatic flavouring is extracted.
