| 英文简介 | Artificial planting of Cistanche deserticola Y.C.Ma is a sunrise industry for preventing windstorms and fastening sand, improving ecological environment and increasing the income of peasants, which has been great ecological benefits, economic benefits and social benefits. But the lack of elite variety is an important factor to restrict the development of its sand industry. From the parasitic relationship viewpoint, the project analyzes the natural population's genetic diversity of C. deserticola whose host is Haloxylon ammodendron and other plants in desert from the four major parts of the Gurbantunggut Desert using ISSR technology. Thus，we can analyze the characteristics of C. deserticola genetic diversity and the genetic relationship of different C. deserticola populations from different scales and reveal the characteristics of its ecological adaptation and diversity distribution. At the same time, the project establishes the integrative fingerprint database combining the diversity morphology and its main active components of C. deserticola to illuminate the effects of origin, populations and host on its genetic diversity and determine the correlation and intrinsic relationship about genetic variation with morphogenesis and quality formation. Through clearing the genetic relationship of different C. deserticola germplasms from Gurbantunggut Desert, the project provides the basis for the botanical classification, the technology for the intellectual property protection and molecular identification, moreover the core germplasm for variety selection, and provides the molecular genetics basis for preserving and utilizing the germplasm resources economically and effectively as well as. |
