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)是与植物根相关的土壤真菌，能促进包括大多数农作物在内的大多数植物对资源的吸收。它们还会影响植物的防御，提高土壤质量。AM真菌的功能因物种和菌株的不同而有很大差异。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他们自己的AM真菌培养所需的专业知识或设施，因此培养物的可用性可能会限制科学进步。该项目将通过一个名为(泡囊)丛枝菌根真菌国际培养集(INVAM)的培养集来支持对这一重要的土壤真菌群的研究。这是世界上最大的这类真菌的培养库，包括数百个单独的分离物。这一收集将促进AM真菌生物学、遗传学、生态学和分类学方面的知识的发展，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INVAM培养的实验模块，以支持K-12下一代生命科学标准。有关植物生长、土壤健康和生物多样性重要性的标准都可以得到收集的支持。INVAM一直是科学界最大的培养提供者，也是鉴定AM真菌物种的主要资源。INVAM维护着数量最多的参考文化，即与凭证标本图书馆和物种描述相联系的文化。这些参考培养物是开发和测试新的环境测序方法的关键资源，环境测序是研究田间AM真菌模式的潜在有效方法。该项目将通过测序努力最大限度地发挥参考培养物的价值。INVAM的核心使命是保存加入并为用户社区提供活的文化。INVAM还通过INVAM网站提供关于收集协议和政策、方法、分类以及关于加入和活跃/储存的文化的可搜索数据库的全面信息。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真菌的代表，以及高价值种质，包括用于基因组计划的菌株和已知的高效菌根共生体。自1990年以来建立和管理INVAM的约瑟夫·莫顿博士于2017年退休。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。这一举措在整个项目期间分阶段进行，以确保文化的可生存性。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
