Tuesday Afternoon Ecology and Adaptation Wang, Ying [1]. Genetic Diversity and Sustainable Utilization of Chinese Medicinal Plants: Lycium and Epimedium. MEDICINAL plants, which have been widely used as natural medicines in China and east Asia for more than 2000 years since the first record in the classical Chinese pharmacopoeia – ‘Shen Nong Ben Cao Jing’. Traditional Chinese medicine, based primarily on plant materials, has also become one of the fastest-growing healthcare choices in the Western world. Since most of the Chinese medicines are produced using wild plants, a large number of medicinal plant species are endangered or endemic in the wild due to overharvest and habitat deterioration. A comparative genomics project was initiated to reveal the genetic mechanism of active constituents in two major Chinese medicinal plant genera, Lycium and Epimedium, for the sustainable development of Chinese medicines. Both fruits, ‘go qi zi’ (or wolfberry), and root bark, ‘di gu pi’, of Lycium species have affinity for the liver, lung, and kidney channels. Dry leaves of Epimedium species have pharmacological effects of promoting sexual behavior, reducing blood pressure, improving anti-inflammation and immunity. First, the genome composition of Lycium chinese and Epimedium pubescens is characterized comparing with the tomato genome. Secondly, the genetic diversity based on the COSII and SSR markers of these two genera will be presented. Thirdly, the active phytochemical compounds and genes controlling their biosynthesis will be explored in these plants.
