丛枝菌根真菌领域专利情报分析

丛枝菌根真菌 (AMF) 与植物共生在提高植物的抗逆性、抗病性和维护植物健康方面发挥着关键作用，其在农业、林业和生态环境等方面的应用受到广泛关注。本研究基于incoPat科技创新情报平台，检索了2019年前国内外丛枝菌根真菌的专利产出，对专利申请数量、主要申请人、技术构成等方面进行了分析，以揭示国内外丛枝菌根真菌领域的研发状况、技术发展趋势和产学研合作情况。近年来，中国丛枝菌根真菌领域专利数量急剧增加，AMF产品化不断加强，AMF应用领域从农业领域向污染修复领域拓展，结合现代生物、信息技术等新兴技术的AMF检测技术和研究方法正在快速发展，新的研发充分考虑了AMF产品化和应用的结合；我国在丛枝菌根真菌领域的专利申请人多隶属高校和科研院所，企业参与度较低。AMF菌种扩繁和污染修复领域的应用已成为焦点，生物和信息新技术成果正引入AMF检测技术的开发；中国在丛枝菌根真菌领域的产学研合作研发亟需加强。

Analysis of patents on arbuscular mycorrhizal fungi

Arbuscular mycorrhizal fungi (AMF) and plant symbiosis plays a key role in improving plant resistance and disease resistance, and maintaining plant health. Their applications in agriculture, forestry and ecological environment have received widespread attention. Based on the incoPat, a technology innovation information platform, retrievals were made of output of patents on AMF at home and abroad before 2019, for analysis of number of applications, technology composition, major applicants, etc. of the patents, in an attempt to reveal R&D status, technology development trends and industry-university-research cooperation in the field of AMF. In recent years, the number of patents has been increasing significantly in China. AMF propagation techniques have been continuously strengthened. Application fields of AMF have extended from agriculture to soil pollution remediation. Testing and research methods are being developed in combination with emerging technologies such as modern information technology, and integration of AMF commercialization and application is fully considered in the new R&D. At present, most of the patent applicants in this aspect in China are from universities and scientific research institutions, fewer from enterprises. AMF strain propagation and application in pollution remediation have become a focus. Novel technological achieved in the fields of biology and information science are being introduced into the development of AMF detection technology. In China, the industry-university-research cooperation in this field needs to be strengthened urgently.
