Arbuscular mycorrhizal (AM) fungi are soil fungi that associate with plant roots and improve resource uptake of the majority of plant species, including most crop plants. They also impact plant defenses and build soil quality. The functioning of AM fungi varies tremendously between species and isolates. As a result, studies of AM fungi can improve management of agriculture, grasslands and forests. Progress in understanding the importance and optimal management of AM fungi depends upon tests of AM fungi cultures. Unfortunately, few researchers have the expertise or facilities necessary to develop or maintain their own AM fungal cultures, and therefore the availability of cultures can limit scientific progress. This project will enable the study of this important group of soil fungi through support of a culture collection called the International culture collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM). This is the largest culture collection of this type of fungi in the world and includes hundreds of individual isolates. This collection will enable advancement of knowledge on AM fungal biology, genetics, ecology, and taxonomy, as well as applications of AM fungi for commercial purposes. This project will also promote the exploration of science by the private sector and by students of all ages and abilities. The project will develop modules on experimentation using INVAM cultures that support the K-12 Next Generation Life Science Standards. Standards related to plant growth, soil health and the importance of biodiversity can all be supported by the collection.INVAM has been the largest provider of cultures to the scientific community and has been the primary resource for identification of AM fungal species. INVAM maintains the largest number of reference cultures, cultures that are linked to a library of voucher specimens and to species descriptions. These reference cultures are a critical resource for the development and testing of new approaches to environmental sequencing, a potentially powerful method to study patterns of AM fungi in the field. The project will maximize the value of the reference cultures through sequencing efforts. The core mission of INVAM is to preserve accessions and provide living cultures to the user community. INVAM also provides comprehensive information on collection protocols and policies, methodology, taxonomy, and a searchable database for accessions and active/stored cultures via the INVAM website. Users include teachers and students from high schools through graduate programs at universities, researchers, and industry clients. Stocks include representatives of 95 AM fungal species, and high value germ plasm including strains used for genome projects and strains known to be highly effective as mycorrhizal symbionts. Dr. Joseph Morton, who built and curated INVAM since 1990, retired in 2017. This project secures the future of the INVAM collections by moving it to the University of Kansas. The move occurs in phases through the duration of the project to ensure culture viability.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

丛枝菌根真菌（AM）是一种与植物根系相关的土壤真菌，可以改善大多数植物物种的资源吸收，包括大多数作物植物。它们还会影响植物的防御能力和土壤质量。AM真菌的功能在物种和分离株之间差异很大。因此，对AM真菌的研究可以改善农业、草原和森林的管理。了解AM真菌的重要性和最佳管理的进展取决于AM真菌培养的测试。不幸的是，很少有研究人员拥有开发或维护自己的AM真菌培养所需的专业知识或设施，因此培养物的可用性会限制科学进步。该项目将通过支持国际（水泡）丛枝菌根真菌（INVAM）培养收集，使这一重要的土壤真菌群的研究成为可能。这是世界上这类真菌最大的培养集合，包括数百个单独的分离株。该收集将使AM真菌生物学，遗传学，生态学和分类学的知识进步，以及AM真菌的商业应用。该项目还将促进私营部门和所有年龄和能力的学生对科学的探索。该项目将开发使用支持K-12下一代生命科学标准的INVAM培养的实验模块。与植物生长、土壤健康和生物多样性重要性有关的标准都可以通过收集得到支持。INVAM一直是科学界最大的培养物提供者，也是鉴定AM真菌种类的主要资源。INVAM拥有最多的参考培养物，这些培养物与凭证标本库和物种描述相关联。这些参考培养物是开发和测试环境测序新方法的关键资源，是研究AM真菌在该领域模式的潜在强大方法。该项目将通过测序工作使参考培养物的价值最大化。INVAM的核心使命是为用户社区保存藏品，并提供鲜活的文化。INVAM还通过INVAM网站提供有关收集协议和策略、方法、分类以及可搜索的数据库和活动/存储文化的全面信息。用户包括从高中到大学研究生课程的教师和学生、研究人员和行业客户。库存包括95种AM真菌物种的代表，以及高价值的种质，包括用于基因组计划的菌株和已知作为菌根共生体非常有效的菌株。Joseph Morton博士于2017年退休，他从1990年开始建造和策划INVAM。该项目通过将INVAM藏品转移到堪萨斯大学来确保其未来的安全。为了确保文化的生存能力，迁移在项目期间分阶段进行。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
