Engineered Chinese shrub produces high levels of antimalarial compound

Artemisinin is a potent antimalarial compound produced naturally in low amounts by the Chinese shrub Artemisia annua, commonly known as sweet wormwood. Researchers in China now report a high-quality draft genome sequence of A. annua and their use of this information along with gene expression data to metabolically engineer plant lines that produce high levels […]
