项目摘要

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 (AM) 真菌是土壤真菌，与植物根部相关并改善大多数植物物种（包括大多数农作物）的资源吸收。它们还会影响植物防御并改善土壤质量。 AM 真菌的功能在物种和分离株之间存在巨大差异。因此，AM 真菌的研究可以改善农业、草原和森林的管理。了解 AM 真菌的重要性和优化管理的进展取决于 AM 真菌培养物的测试。不幸的是，很少有研究人员拥有开发或维护自己的 AM 真菌培养物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。该项目将通过支持一个名为国际（囊状）丛枝菌根真菌培养物保藏中心（INVAM）的培养物保藏中心来研究这一重要的土壤真菌群。这是世界上最大的此类真菌培养物保藏中心，包括数百个单独的分离株。该系列将促进 AM 真菌生物学、遗传学、生态学和分类学知识的进步，以及 AM 真菌在商业目的上的应用。该项目还将促进私营部门和各个年龄段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 培养物的实验模块。与植物生长、土壤健康和生物多样性重要性相关的标准都可以得到该馆藏的支持。INVAM 一直是科学界最大的培养物提供者，并且一直是鉴定 AM 真菌物种的主要资源。 INVAM 保留着数量最多的参考文化，这些文化与凭证标本库和物种描述相关。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，环境测序是研究 AM 真菌实地模式的潜在强大方法。该项目将通过测序工作最大限度地发挥参考培养物的价值。 INVAM 的核心使命是保存种质并为用户社区提供活的文化。 INVAM 还通过 INVAM 网站提供有关收集协议和政策、方法、分类学以及可搜索数据库的信息和活跃/存储的培养物。用户包括高中教师和学生、大学研究生、研究人员和行业客户。库存包括 95 种 AM 真菌物种的代表，以及高价值种质，包括用于基因组计划的菌株和已知作为菌根共生体高效的菌株。约瑟夫·莫顿 (Joseph Morton) 博士自 1990 年以来创建并策划了 INVAM，并于 2017 年退休。该项目将 INVAM 藏品移至堪萨斯大学，确保了 INVAM 藏品的未来。这一举措在项目期间分阶段进行，以确保文化的可行性。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
