Drug development
The development of medicinal plant resources is a project aimed at preventing and treating diseases.
Disease, the scientific cause of improving human health. In recent years, with the continuous improvement of people's living standards and the growing voice of "returning to nature" around the world, there has been an upsurge of developing medicinal plant resources at home and abroad. Medicinal plants are not only used as Chinese herbal medicines or medical raw materials more effectively, but also widely used in many new fields such as health food, drinks, flavoring agents, spices, cosmetics, botanical pesticides, livestock drugs and so on. This encouraging situation has injected great vitality into the research of medicinal plant germplasm resources as the source of medicinal material production, and also put forward higher requirements. 1 the significance of genetic diversity of germplasm resources in the development of medicinal plants
1 1 1 the concept of "medicinal plant germplasm resources"
"Germplasm resources" are usually used for specific species,
It is all available genetic materials including cultivated varieties (types), wild species, closely related wild species and special genetic materials. The main contents of germplasm resources research are the investigation and collection, identification and evaluation, preservation and application of crop varieties (types) and the study of genetic basis, origin and evolution. Among them, the research on genetic diversity of germplasm resources is a hot spot in germplasm resources research. These all need the right medicine? 580?
Have a better understanding of plant gene polymorphism. However, it is worrying that before human beings make full use of these gene resources, their carriers-germplasm resources-are facing the threat of serious destruction or even loss. Therefore, while perfecting and effectively implementing the laws and regulations on resource protection, we should speed up the cultivation of medicinal plant germplasm. 1 14. In order to obtain good curative effect and experience, the most useful genetic resources must be screened out from many genetic resources before introduction, so as to obtain more products with the same amount of materials. For example, the research on the germplasm resources of the famous anticancer plant Taxus chinensis shows that there are 1 1 species in the world (including 4 species 1 variety in China), and there are many geographical varieties and cultivated species under it. There are no less than 40 geographical varieties of Taxus in Europe alone, and the content of taxol in bark is usually only 0.06544. On the basis of extensive investigation in the United States around 1990, a hybrid T.T. media "hicks II" with the content of 0.0 14% was selected from North American cultivars, which has excellent characteristics such as rapid growth, so it was introduced and cultivated on a large scale. , exclude. DNA .
Application of 2 12 in genetic diversity analysis
Genetic analysis of medicinal germplasm resources, especially perennial medicinal plants, was very difficult in the past. For example, in classical genetics, it takes at least 9 years to compare the genetic differences of wild people who participate in ginseng cultivation through offspring analysis, which makes people flinch from genetic research on medicinal plants with long reproductive cycle. The invention of RAPD in 1990s and the development of high-tech related molecular biology provided a powerful new tool for understanding the genetic background of perennial medicinal plants such as ginseng. This simple and rapid advanced technology enables us to directly compare the subtle differences of genetic material DNA of different germplasm for the first time, and analyze the genetic diversity of germplasm resources with only a small amount of dry matter.
Sex, get rich genetic information. Application of 2 13 in other fields
Through the analysis and comparison of many DNA fingerprints, we can calculate the genetic distance and similarity coefficient between varieties, thus giving the clustering relationship diagram between varieties, and further studying the origin and evolution of varieties. In addition, DNA fingerprinting is also an important tool to construct the genetic map of medicinal plants, which is the file of plant genes and has great reference value for breeding.
In a word, DNA fingerprinting technology has a great application prospect in the research of medicinal plant germplasm resources. More and more research reports show that the application of new DNA fingerprinting technology is promoting the vigorous development of medicinal plant germplasm resources research. 3 references

In 1960s, the International Rice Research Institute in the Philippines and the International Maize and Wheat Improvement Center in Mexico cultivated short-stem (semi-short-stem) high-yield rice and wheat varieties. These varieties are rapidly popularized and applied in developing countries, and with the improvement of irrigation and fertilization technology, great economic and social benefits have been produced. This technological progress mainly focuses on the promotion of improved varieties (short stalks), which is called the first "green revolution" (short stalks). ...
