摘要：

Effects of mechanical wounding on gene expression involved in artemisinin biosynthesis and artemisinin production in Artemisia annua leaves were investigated. HPLC-ELSD analysis indicated that there was a remarkable enhancement of the artemisinin content in 2 h after wounding treatment, and the content reached the maximum value at 4 h (nearly 50% higher than that in the control plants). The expression profile analysis showed that many important genes (HMGR, ADS, CPR, and CYP71AV1) involved in the artemisinin biosynthetic pathway were induced in a short time after wounding treatment. This study indicates that the artemisinin biosynthesis is affected by mechanical wounding. The possible mechanism of the control of gene expression during wounding is discussed.
