The National Wild Plant Germplasm Resource Center(NWPGRC) is one of the 31 national biological germplasm and experimental materials platforms established by the Ministry of Science and Technology and the Ministry of Finance. At present, 11 domestic research institutes and universities engaged in the collection and preservation of wild plant germplasm resources participate in the construction. In order to realize the collaborative work of all participating units in data exchange, resource sharing and statistical analysis of wild plant germplasm resources, The Germplasm Bank of Wild Species with the Science and Technology Information Center, Kunming Institute of Botany, Chinese Academy of Sciences first analyzed the needs of the shared service platform, and then designed the architecture, functional modules, core business processes and databases of the platform. Based on the ASP.NET MVC framework, the shared service platform of NWPGRC was realized by using data quality assurance technology, interconnection technology, authority control technology and security technology. The platform can effectively control the data quality of germplasm resources, realize the data interaction with relevant platforms such as China Science and technology resources sharing network, meet the more complex requirements of authority allocation, and the security of the platform is high. It not only promoted the cooperative work of the participating units in the collection, treatment, preservation and distribution of wild plant germplasm resources, but also provided a convenient way for the vast number of scientific and technological workers to obtain the material objects and data of wild plant germplasm resources, and promoted the sharing of national scientific and technological resources, especially plant genetic resources represented by seeds. It plays an important role in improving the development and utilization of national strategic biological resources. In addition, the design and implementation method of the platform can also provide reference for the construction of resource sharing service platforms in other fields.
