生态文明建设中的植物学：现在与未来——中国植物学会第十五届会员代表大会暨八十周年学术年会

作者： Airong Li Kaiyun Guan Xiaolin Sui Yan Chen Sally e.smith F.Andrew smith Kunming Institute of Botany Chinese Academy of Sciences Soil group School of Agriculture Food and Wine The University of Adelaide Australia

Pedicularis L. (Orobanchaceae) is a large lineage of root hemiparasitic plants, consisting of about 600 described species widely distributed in temperate zones of the northern hemisphere, and best represented (>352 species) in the mountains of SW China. Pedicularis has great ornamental values with striking corolla shapes and colors. In addition, some species have special pharmacological effects and have been used as medicinal herbs. Unfortunately, Pedicularis has been known for difficulty in cultivation and its utilization is greatly hindered. What makes things worse is that some species are threatened or endangered and are in dire need of immediate protection. On the other hand, some Pedicularis species (e.g. P. kansuensis) are undergoing rapid spatial expansion and strongly influencing plant community structures and productivity in the ecosystems that they occur. Plant resource utilization as well as plant biodiversity conservation calls for a better understanding of basic biology of Pedicularis, particularly their interactions with host plants and other biotic and abiotic factors. However, despite that parasitic habit of Pedicularis has been known since 1847, investigation on parasitism of Pedicularis has been rare. To our knowledge, the small number of studies (mostly very preliminarily) on the parasitic biology of Pedicularis are exclusively on european or American species. Parasitic biology of Chinese Pedicualris species and their interactions with environmental factors have hardly been documented. Our research interests in Pedicularis are broad within the areas of understanding their parasitic biology and their interactions with other biotic and abiotic factors. Particularly, we are keen to research into the following aspects concerning the root hemiparasites: 1) host dependency and selectivity and relevant mechanisms;2) tripartite interactions among Pedicularis, arbuscular mycorrhizal (AM) fungi and their host plants from a nutritional perspective;3) plastic

A glasshouse pot experiment was conducted to investigate effects of the arbuscular mycorrhizal fungus Glomus mosseae on the growth of Vicia faba and toxicity induced by heavy metals （HMs）（Cu, Zn, Pb and Cd） in a field soil contaminated by a mixture of these metals. There was also uninoculation treatment （NM） simultaneously. Mycorrhizal （GM） plants have significantly increased growth and tolerance to toxicity induced by heavy metals compared with NM plants. P uptake was significantly increased in GM plants. Mycorrhizal symbiosis reduced the transportation of HMs fi＇om root to shoot by immobilizing HMs in the mycorrhizal, shown by increasing the ratios of HMs from root to shoot. Oxidative stress, which can induce DNA damage, is an important mechanism of heavy metal toxicity. GM treatment decreased oxidative stress by intricating antioxidative systems such as peroxidases and non-enzymic systems including soluble protein. The DNA damage induced by heavy metals was detected using comet assay, which showed DNA damage in the plants was decreased by the GM treatment.

对石油和天然气投资机会的评价常常过份地强调了未来的利润(假定油气井能投产),而忽视了系统地评价与每项计划有关的地质的和财务的风险。由于存在钻干井的风险,石油和天然气公司都力求把未来的利润增加到最大,而把财务风险减少到最小。
