Effect of wounding on gene expression involved in artemisinin biosynthesis and artemisinin production in Artemisia annua

Effect of wounding on gene expression involved in artemisinin biosynthesis and artemisinin... Abstract-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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
