Non Technical Summary
Seeds are the fundamental unit of plant reproduction and the basis of the human food system. From vegetable seed, to certified cereals, to native species for rangeland restoration, seed production comprises a major agricultural and natural resource industry in the Intermountain Pacific Northwest. A skilled and technically educated workforce is needed to maintain this industry and produce quality seed for agriculture and plant restoration. However, talent must frequently be imported and regional educational programs have been inadequate to inform and educate students, youth, and the public as to the impact and importance of seeds and a seed production industry. Moreover, the industry is poorly represented by college graduates from minorities, women, and economically disadvantaged groups.We propose an immersive, integrated research and extension experience for 2nd- and 3rd-year undergraduates from host institutions and regional 2-years colleges to explore the applications of seed microbiology to regional agriculture and habitat restoration. Students from underrepresented groups will be actively recruited. Students in this program may choose from applied research projects in collaboration with regional industry and agencies examining the effects of seed microbes on plant regeneration and an Extension education project designed to raise awareness to seed science and seed production industry among agricultural producers, K-12 youth, and the public.Students will conduct research projects the look at the effect of fungi and bacteria that live inside seeds on seed quality (e.g. wheat seed quality for bread flour) and seed survival and seedling survival in harsh environments (e.g. post-fire revegetation sites); how non-pathogenic seed-associated bacteria and fungi might defend seeds and host plants against pathogen and insect attack; how inexpensive recreational-type drone technology might be adapted to daily use in farm fields and restoration sites for basic pathogen sampling and seedling development monitoring by producers; and how interactions between pollinators and seedborne fungi and bacteria may interact to impact seed quality and seedling survival and pollinator health and survival. Students will also have the opportunity to engage K-12 youth to build awareness of the practical importance of seeds to human survival and the importance of seed science to world ecology.The goal of the Applied Seed Microbiology REEU is to introduce sophomore and junior undergraduates, K-12 youth, and professional and lay audiences to the importance of seed science and seed production and industry toagriculture and natural resources and to explore application of seed microbiology in regenerative agriculture and habitat restoration. Our program seek to build collaborations among research, liberal arts, and community colleges; the agricultural seed industry; and regional habitat restoration professionals and expand our knowledge and understanding of seed science.

Goals / Objectives
The overarching goals of the Applied Seed Microbiology REEU is to introduce sophomore and junior undergraduates to the importance of seed science and seed production and industry to agriculture and natural resources and to explore application of seed endophytes in regenerative agriculture and habitat restoration. Program objectives are to 1) provide undergraduate students with an experiential and collaborative research and Extension traineeship; 2) increase knowledge and awareness of agriculture, habitat restoration, seeds, and seed-microbiology and career opportunities in these fields for all participants; 3) build capacity for regional collaborative education and research in seed science, regenerative agriculture, and habitat restoration; and 4) develop seed microbe-based solutions for seed health and disease management that affect regional seed production. Our program will implement lasting collaborations among research, liberal arts, and community colleges; the agricultural seed industry; and regional habitat restoration professionals. Through this program, we will develop tomorrow's agricultural leaders with new technology skills, strong collaboration skills, resourceful data analytical skills and clear communication skills.
Project Methods
Our methods for meeting our goals and objectives will be to actively engage participants and collaborators. 1) Students will participate in either a research project or Extension outreach/education project. We will mentor research track students through the scientific process to develop and test hypotheses, plan and implement experiments to test hypotheses, collect and analyze data appropriately, and present results to professional and casual audiences. Students across program sites will work together to address research questions and provide support for colleagues by exploiting site-specific advantages (access to seed, plant materials, curricula, etc.). Extension track students will learn to work with stakeholders to address applied questions in the field and work with the Extension mentor to develop educational curricula for youth and adult audiences through the process of identifying the need, building the curriculum, and publicizing findings, educational opportunities, and education and outreach events. 2) Research projects that students engage in will specifically address seed science questions as related to seed-microbe interactions. Students will deliver their findings to a wide variety of both professional and lay audiences, youth and adult. They will learn to take complex research questions and findings and deliver them in an informative and educational format, increasing public and stakeholder awareness. Students will have opportunities to tour seed production and processing facilities, learn about industry research, shadow industry researchers, and collaborate on industry questions as well as present their own research to industry groups. They will also visit labs and field sites to get a broad view of seed research, industry, and educational career opportunities. 3) Through working with recruiters at reginal community colleges and four-year colleges and universities, we will seek to build a recruiting pipeline for cross-institutional internship programs and build awareness of outreach and Extension programs and activities. We will also reach out to regional seed production industries to build on current regional research collaborations for greater youth involvement and career recruitment and education piplines. We will likewise work with regional agencies for greater student research and field collaboration opportunities in restoration and regenerative agriculture. 4) We will use applied experimentation to test seed microbe technologies for pre- and post-seeding treatments as seed coat treatments, aerosolized floral and foliar applications, and pollinator-vectored products to improve seed quality, seedling vigor and establishment, and adult plant health and yield. We will also test cost-effective drone technologies for monitoring seed pathogen and seed microbe movement, sampling pathogen ad endophyte drift, tracking seedling responses in-field to seed treatments and revegetation response data for larger areas. We will also develop a youth citizen science program for testing efficacy of a regional seed pathogen against two major insect pests: Mormon cricket and clearwinged grasshopper.

Outputs
Target Audience:The targeted audience for this project are undergraduate students interested in applied plant microboligy for regenerative agriculture and habitat restoration in the Intermountain West. The project focuses on connecting undergraduate students and researchers, as well as important producers and stakeholders in regenerative agriculture and restoration. Changes/Problems:It should be noted that Project Director George Newcombe has retired from the University of Idaho as of June 2024 and Dr. Charles Goebel will be the new Project Director for this grant award. Dr. George Newcombe will continue to help with outputs from this grant award (e.g., publication of the manuscript that is being drafted). Dr. Mary Ridout (previously at Treasure Valley Community College) and Dr. Julie Beckstead (Gonzaga University) will be terminating their subcontracts with the University of Idaho and will not continue to work on this grant award. Due to the switch in Project Director in Spring 2025, there was not time to activiely recruit a chort of students for the project for the summer of 2025. As such, we will be requesting a final No-Cost-Extension of the project to train and mentor a cohort of students at the University of Idaho for FY 2027. The focus of these student cohorts will be on post-wildfire restoration and riparian restoration. What opportunities for training and professional development has the project provided?A total of 8 students were mentored on this grant from April 2024 to April 2025. Students from past years were survey to determine how their career paths have been impacted from the opportunities that we provided. We have two students that were accepted to graduate schools for 2025-2026, one student is completing their M.S. degree, six students graduated with B.S. degree in the sciences, and multiple past students are employed in natural resource related fields. Student ratios varied between the institutions: Gonzaga University was 1:5 (mentor to mentee), University of Idaho was 1:2, and Treasure Valley Community College was 1:1.

Abstract Roughly 1/3 of the pathogens of cheatgrass in North America are biotrophs that cause obvious disease with typical signs and symptoms. Some of the remaining pathogens also cause obvious disease, but others cryptically depress germination or growth or fecundity without signs and symptoms. Among this remainder are cryptic pathogens that can be isolated from plants other than cheatgrass. To our knowledge no pathogen of another plant has ever been tested for negative effects on cheatgrass. Here, we tested strains of Bacillus bacteria that were not obvious pathogens but they had displayed negative effects on emergence of B. tectorum in preliminary research. One strain was isolated from B. tectorum but four more were from creosote bush, Larrea tridentata (family Zygophyllaceae), a common shrub in deserts of the American Southwest. In our various germination and emergence assays the only consistently negative strain was one, 'SB-4', from creosote bush. This cryptic pathogen completely suppressed cheat grass germination after just a single hour of direct contact. We also compared inoculation methods: two methods that depend on direct contact between Bacillus cells and seeds of B. tectorum, and a third method, the soil drench, that does not ensure direct contact. Only the direct-contact methods reduced emergence of B. tectorum; soil drench had a weak effect on emergence. Furthermore, 48 hours of direct contact reduced emergence significantly more than 24 hours. In fact, the strongest pathogenic strain, 'SB-4', completely suppressed emergence of B. tectorum following 48 hours of direct contact. The search for useful pathogens of invasive cheatgrass, previously confined to microbes isolated from cheatgrass, should include cryptic pathogens from unrelated plants.'SB-4' in particular merits further testing. Introduction Bromus tectorum, or cheatgrass, is a very common invader of plant communities in western North America (Mack, 1981). Native to Eurasia, the initial phase of its invasion of North America may have been spurred by enemy release, a key factor in many plant invasions (Mitchell and Power, 2003). Enemy release can gradually be eroded by further pathogen introductions, particularly if the latter are pathogens from the native range. Although pathogens of Bromus tectorum have been slowly accumulating in North America since B. tectorum invaded (Meyer et al, 2016), the plant remains highly successful. A total of 52 fungal pathogens have now been recorded on B. tectorum in the USA (Farr and Rossman, 2024). The 52 are 'obvious' pathogens in the sense that they are associated with characteristic signs and symptoms, and they belong to taxa with proven pathogenicity. Despite the total of 52, greater than that of any single in the native range of cheatgrass, individual plants in North America tend still to be free of obvious pathogens. Even stand die-offs have remained local and sporadic (Ricks et al, 2021); no single pathogen at present affects the entire, invaded range in North America. Bacterial pathogens of B. tectorum have been less studied, but there is one well known example that will be further developed below. Of the 52 fungal pathogens on B. tectorum in the USA, 17 belong to taxa entirely comprised of specialized, biotrophic parasites: 3 powdery mildews (i.e., order Erysiphales), 7 rust fungi (i.e., order Pucciniales), and 7 smut fungi (i.e., class Ustilaginomycetes). The other 35 are necrotrophic fungi that are endophytic in some plants, but pathogenic in yet others. An example of this bimodality is Fusarium culmorum, an endophyte not only in B. tectorum, but also in Populus trichocarpa; an endophyte from the latter was experimentally demonstrated to retain its pathogenicity towards wheat (Newcombe et al, 2020). An endophytic isolate of F. culmorum from poplar only caused disease in inoculated wheat, and not in inoculated P. trichocarpa. The same fungus, F. culmorum, has also been reported from B. tectorum (Sprague, 1950). However, no experimental inoculations with a cheatgrass isolate have been carried out. Inoculations with most of the other necrotrophic taxa in the National Fungus Collections database have also never been attempted. But, its function as either an endophyte or a pathogen in B. tectorum has never been investigated. In western North America, there must be many potential cheatgrass pathogens among endophytes of the thousands of co-occurring plants.This would be true not only for fungi but for bacteria as well. Interest in relationships among plants, on the one hand, and species of the genus Bacillus, on the other, has focused on deploying these bacteria in agricultural ecosystems (Saxena et al, 2020). Central to that interest is the ability of Bacillus to promote the growth and control the pathogens of a wide range of crop plants. However, the roles of Bacillus in natural plant communities are still largely unstudied. So as the need for greater agricultural yields increases with increasing human populations, the deployment of biscuits in such systems will increase commensurately. However, spillover into natural ecosystems is relatively unstudied. It has been difficult to improve the health of plants and animals by manipulating their respective microbiomes; complex causality is at the root (Anderson, 2023). But we are getting closer to our goal for plants. Seed microbes are our focus because they are highly antagonistic/combative (Fira et al, 2018; Newcombe et al, 2018). Our current focus, Bacillus species, are not only known for their combativeness but now we know that they can be sourced or isolated from seeds (Newcombe et al, 2023).

Outreach: Development of two learning games about seeds and their endophytes by undergraduate participants. 1) High School game called "Glorious Germination" and 2) Grades 3rd-5th game called "Seeds' Hidden Helpers". Games are being disseminated to regional schools and publications in education journals are in the works. Games were played with over 100 undergraduate students and also with 1-6 grade students at the Salish School of Spokane. Communication with larger community: 1) Science learning game materials made available on the program's website, 2) YouTube video about the science learning game made available online, 3) news article about plant curriculum featured in the Gonzaga University Bulletin. Development of plant-related suite of courses for Gonzaga University, including modification to two existing courses (now Plant Population Ecology and Plant Community Ecology) and a newly designed Plant Propagation and Restoration course with course-based undergraduate research experiences associated with the topic of this grant. Networking, career exploration, and direct interactions with seed industry partners (i.e., private seed growers, private seed processing companies, and federal seed banks) and plant related careers (i.e., botanical gardens, US Forest Service, and Bureau of Land Management, etc.). Over 11 professional development workshops offered to summer undergraduate students in the 2023 program.

      Target Audience:Project title: Undergraduate training in applied plant microbiology for regenerative agriculture and habitat restoration in the Intermountain West Subaward No.: AS5339-691611 Mid-April 2022 to mid-April 2023: With summer students we held weekly Zoom lab meetings at all three institutions. Activities consisted of discussion of primary literature, sharing of research projects, and trouble-shooting research problems that surfaced. Students were required to write a short reflection for each primary literature article read along with reflections about the field trips. Connections were made with seed producers, government agencies involved in preservation of crop plants and native plants. Field trips for the 2022 program were built around these connections that we will repeat in 2023 with a new cohort of summer students. Additionally, we have set up an academic program at Treasure Valley Community College in Oregon that will accept research students during the academic year and will be affiliated with our Seeds for The Future program in 2023. Date Activity May 16 First day for 8-week summer research program May 16 Field Trip 1: Gonzaga only. Visit Clearwater Seeds Company, Spokane, WA May 18 Field Trip 2: Both Gonzaga University and University of Idaho. Visit Thorn Creek Native Seed Farm, Genesee, ID. June 13 First day for 4-week summer research program June 21 Field Trip 3: Both Gonzaga University and University of Idaho. Visit Plant Germplasm Introduction and Testing - USDA Agricultural Research Service lab, Pullman, WA. July 6 Field Trip 4: Both Gonzaga University and University of Idaho. Visit Atomic Force Microscopy, Spokane WA. Seeds For The Future Symposium 2022. Both Gonzaga University and University of Idaho. Students each presented their research. July 8 Last day for 4-week and 8-week summer research program. A website was developed to communicate to the public and potential applicants about our Seeds For The Future program (www.gonzaga.edu/SeedsForTheFuture). The website contained the application form links along with dissemination about Seed Industry careers related to our summer 2022 field trips. We advertised our program with 18 regional colleges and universities in our region. From this recruitment we obtained 19 applicants and selected 9 undergraduate students from 5 regional universities to be our 2022 Cohort for our program. Participants 2022: nine participants on two university campuses; Students represented three states in the Inland Northwest; three males, one nonbinary, and five females; underrepresented students included one Hispanic female and one LBGQT student; three students were prior community college students; two high-financial need students; and all nine students were undergraduates at local universities at the time of application.

Changes/Problems: Changes/Problems: During the summer of 2022, we elected to host students for 8-week positions and 4-week positions. This was a challenge to train the 4-week students and develop research projects within this short time frame. For this reason we have shifted to hosting fewer students but for a longer period of time in Summer 2023. Additionally, in Summer 2022 our mentor: fellow ratio was 1:5 at Gonzaga University and 1:2 at University of Idaho. The high ratio of students to faculty was challenging at Gonzaga University. Therefore in Summer 2023 an additional research mentor will join the team, lowering the mentor:student ratio. What opportunities for training and professional development has the project provided? Our goals were to provide research training and professional devlopment opportunities to prepare students for careers in agricultural and natural resources. We accomplished this goal for Summer 2022 and will continue for Summer 2023. How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?In Summer 2023 we will follow up on the exploratory research of Summer 2022 and complete work that will support the publication of refereed manuscripts in subsequent periods.

      Impacts
      What was accomplished under these goals? Our 2022 activities were exploratory but they set us firmly on the path toward summer 2023 projects that will result in publications. We made all of the desired connections in 2022 with target audiences, and we have continued to build our network since then. We are not only discussing primary literature but we are bringing into our weekly meetings significant accomplishments in the global arena of outreach writing about seeds. The latest example of the latter is the following: Reading Article - News:To regrow forests, the U.S. needs billions of seeds--and many more 'seed hunters'. National Geographic. This is an energizing read that expands students' horizons.

        Target Audience:This is the first Progress Report.In addition to the late receipt of funds for a 2021 program [from mid-May to mid-July], PI Mary Ridout changed positions in summer of 2021, from UI Extension faculty member to a faculty member of Treasure Valley Community College. This change then required a corresponding change in PI where Newcombe [UI] became PI; Ridout also had to modify her objectives to fit better with her new position at Treasure Valley Community College. Changes were approved by USDA, and then we began preparing for the 2022 program. We developed a website, advertising material and invited applicants for 2022. By April 14, 2022, we had selected the 8 students for the 2022 Program. Changes/Problems:Funding received in April 2021 was not in time to properly advertise and recruit students for summer 2021. Then Dr. Mary Ridout changed jobs from UI Extension to Treasure Valley Community College faculty. Then, we had to be approved for the PI change from Dr. Ridout to Dr. Newcombe, still at UI. What opportunities for training and professional development has the project provided?None yet [as of April 14, 2022]. How have the results been disseminated to communities of interest?We communicated with eight motivated students who were eager to enter the mid-May to Mid-July 2022 Program. What do you plan to do during the next reporting period to accomplish the goals?We will report on the successful 2022 program and plan the 2023 program before reporting on the period of April 15, 2022 to April 14, 2023.Some of the highlights of our 2022 program will be continued in terms of documentation and further analysis.

        Impacts
        What was accomplished under these goals? We accomplished all organizational tasks needed to launch our mid-May to mid-July 2022 program for eight students: four at Gonzaga U. and four at UI. We also established regional connections that we needed for relevant field trips.
