Non Technical Summary
The USDA-NIFA's innovative research support to 1890 Institutions has fueled numerous agricultural advancements that have enhanced their infrastructures. These sustainable integrative management practices drove research efforts towards productions resulting in higher yield and disease resilience. Currently, of specific interest to producers, small-scale farmers and stakeholders are environmentally friendly crop propagation methods. Hence, leveraging new and existing technologies to influence biological processes in increasing plant breeding efficacy is key to addressing these interests. Plants exposed to magnetic fields have shown a variety of growth responses. Although magnetic field exposure effects to stimulate growth are well-documented, the impact of magnetic field exposure effects in plants is not well-understood. Thus, a comprehensive understanding of biomagnetic responses in plants necessitates new in-depth approaches. Our preliminary magnetic field exposure studies resulted in increased biomass production in different plant species thus serving as a platform for our proposed research. The objectives are to 1) screen candidate plant growth responses based on overall biomass production and selected physiological growth parameters; 2) identify the effects of magnetic fields in plants by transcriptome and metabolic profiling and characterize host responses to pathogens in exposed plants; 3) analyze the impact of a simulated Mars' magnetic field on germination and plant growth. The proposed study has the potential to 1) contribute to fundamental understanding of magnetic field effects on crop development; 2) provide stakeholders and crop producers with a viable, safer option for enhancing plant breeding efficacy; 3) provide student experiential learning in FANH with hopes of producing highly-skilled agricultural workers; 4) create new insight in on the effects of extraplanetary magnetic fields on plant breeding as we continue to explore space travel; 4) improve the existing research infrastructure at a historic 1890 research and teaching institution.

Goals / Objectives
The overarching aim of this project on developing magnetic field exposure protocols to increase plant breeding efficacy aligns with the strategic priorities of USDA-NIFA whose contributions have fueled numerous agricultural advancements and have enhanced the research infrastructures of 1890s Institutions. Currently, of specific interest to producers, small-scale farmers and stakeholders are environmentally friendly crop propagation methods. Hence, leveraging new and existing magnetic field technologies to influence biological processes in increasing plant breeding efficacy is key to addressing these interests. Furthermore, as we explore interplanetary travel, elucidating the effects of magnetic fields on plant growth and development becomes increasingly important. Interestingly, our preliminary magnetic field exposure studies resulted in increased biomass production in different plant species. The objectives are to 1) expose plant to magnetic fields and screen candidate plant growth responses based on overall biomass production and selected physiological growth parameters; 2) identify the effects of magnetic fields in plants by transcriptome and metabolic profiling and characterize host responses to pathogens in exposed plants; 3) analyze the impact of a simulated Mars' magnetic field on germination and plant growth; 4) Develop specific magnetic field exposure protocols for plants for crop producers and plant breeders. The proposed study has the potential to contribute to fundamental understanding of magnetic field effects on crop development and provide student experiential learning in FANH through a collaborative, interdisciplinary approach. The outcome will enhance the University's research capacity via the development of precise phenotypic and molecular screening protocols, and new agricultural research equipment key to students' knowledge of modern precision agriculture.
Project Methods
The foundational objective (Objective I) is to screen for plant species that display increased biomass production in response to MFE. Our project will involve a greenhouse-based screening of 10 different crop species under conventional (soil) and hydroponic cultivation. Plant seeds will be exposed to magnetic fields of different intensities. Plant species will include okra, squash, lettuce, watermelon, southern field peas, tomato, as well as crops of economic value in Alabama (sweet potato, corn, peanut, and blueberry). The screening will be based on maturity group experiments using conventional production methods in a greenhouse setting. This experimental design will serve as the basis of study for our non-conventional production analyses (hydroponic and in-vitro). The experiments will be conducted as a randomized complete block design with a 10x3 factorial treatment arrangement and six replications. The treatment combinations will comprise of 5 magnetic field exposure times of 20, 40, 60, 80 and 100 minutes at different magnetic field intensities. Seeds from each crop species will be placed in Petri dishes containing moistened filter paper and exposed to magnetic field treatment. After treatment, exposed seeds and non-exposed controls will be transferred to experimental testbeds filled with soil and cultivated at 25±5°C under greenhouse conditions. Phenotypic responses of sets of seeds and plants will be assessed based on the following growth parameters: (i) plant height, (ii) stem diameter, (iii) leaf expansion and unfolding rates, (iv) specific leaf weight, (v) days to flowering and appearance of first fruits, (vi) fruit weight and size (vii) leaf area index, (viii) fresh and dry root weight, (ix) plant fresh and dry mass and (x) chlorophyll index. Leaf and root samples will be harvested during multiple phases of plant development (seedling, early growth, reproductive stages) and subject to preliminary NMR-based metabolic profiling. In this part of the study, a camera-based automated plant growth monitoring system will be developed to assess biomass production by extracting various phenotypic features of the crop species under consideration. Objective II: To demonstrate a fundamental correlation in phenotypic and molecular responses to MFE, Objective II will engage in transcriptome and metabolic profiling of candidate plant species under MFE. Candidate plant species from Objective I will be subjected to further analyses through transcriptome profiling via RNA-Seq. MFE will be primarily based on the optimal time interval and intensity that showed superior phenotypic responses from Objective I. Total RNA will be isolated from plant tissues and mRNA will be purified and stored at -80C for transcriptome profiling. RNA Sequencing services, primary sequencing analysis, data visualization and assistance in manuscript preparation will be provided by the Bioinformatics Core Facility at U.C. Davis. Differential gene expression patterns of the most significantly expressed candidate transcripts will be validated using quantitative real-time PCR. Preliminary gene expression analyses on genes involved in growth and development will be performed using qPCR to assess transcriptional changes during cultivation. Exposed and control seeds from candidate plants species will be further assessed for viability. After MFE, seeds will be germinated in growth chambers and germination and leaf temperature during seedling growth will be measured via the use of thermal cameras. The resulting image analysis will be analyzed as mentioned previously and used in the construction a library of "thermal fingerprints" to allow for rapid detection of seed viability. Seeds will be considered germinated when their radicule extends to 1mm. Temperature data for each individual pea seed will be calculated every 20 s over 5 d and averaged at 5-min intervals. The physical assessment will include (i) days to germination, (ii) rate of germination, (iii) percent germination and (iv) seedling vigor. At each harvest, samples will be analyzed for any changes in metabolic profiles through NMR and MS analysis. NMR spectra of foliar and root metabolites will be subjected to multivariate analyses. Sub-Objective II - To identify the host response to nematode infection in plants exposed to magnetic fields. Seeds and/or cuttings from candidate plant species will be exposed to the magnetic field intensity and time interval that correlated to the best growth and development in the previous trial and transferred to 150 cm3 pots containing a 3:1 sterilized mixture of sandy and field soils and cultivated in a plant growth chamber. An identical set of untreated samples will serve as controls. Root-knot nematodes will be cultured on susceptible tomato varieties and eggs extracted using the NaOCL method (Hussey and Barker, 1973). After a second MFE, approximately 10,000 nematode eggs and J2 larvae will be injected into the soils of magnetic field-treated and untreated control plants 14-days after planting. Plants will be further cultivated (25-28oC, 16hr light) and watered as needed. An overall phenotypic assessment will be conducted at harvest and root samples will be subjected to RNA-sequencing analysis to identify differential gene expression patterns in exposed and unexposed plants cultivated under nematode burden.Objective III: The proposing team will engage in experiments, which will subject the selected plant species to the magnetic field experienced by a Mars orbiter. The Magnetic Coil Test Facility at TU can emulate a dynamically changing magnetic field, which is experienced by orbiters around any planet. A low altitude Mars orbit similar to the orbit of the International Space Station around Earth will be simulated by the Helmholtz coil system and the selected plant species will be periodically subjected to the dynamically changing magnetic field in such orbits. The specimens subjected to this field, along with control specimens will be monitored in plant growth chambers. At critical stages, the methods discussed above will be employed to conduct a micro-analysis. The techniques discussed in Objective I and Objective II will be used to analyze the effect of controlled exposure to this field.Evaluation: Dr. Mortley will lead the evaluation efforts and all internal reviews will be conducted under his advisement. The team intends to seek resources from their Dean's office to evaluate the progress of the project on a yearly basis. The respected Deans of the three colleges of TU, involved in this project are all accomplished researchers. Two of the Deans, Dean Prakash of College of Arts and Sciences and Dean Hill of College of Agriculture, Environment and Nutrition Science, have established expertise in the proposed field of research. As captured in the Project Timeline and Organization Plan, the proposing team will update the Deans' offices once a semester and will seek a comprehensive evaluation of the research once a year. All the three Deans have committed full support and the proposing team will capitalize on this support to seek a yearly evaluation of the proposed project. Throughout the workshop training, mentors will interview students to identify the applicability of workshop materials, lectures and report on the relevance of the workshop to the research objectives. After the successful implementation of the training workshops, a student survey will be submitted by mentors to gauge the student's perception on the impact of training events and to determine any influence this project may have on their career and research goals.

What was accomplished under these goals? Trials on Physio-Morphological Parameters: Following exposures, seeds of collards and tomatoes were sown in potting soil within a controlled greenhouse environment. Over a six-week period, key growth parameters such as leaf dimensions (length and width), stem diameter, chlorophyll content, and plant height were meticulously recorded on a weekly basis. Statistical analyses, including Fisher's Protected LSD test and post-hoc Tukey's test, were employed to discern any mean differences between the control and exposed groups. The findings revealed no statistically significant disparities in any of the growth parameters between the two groups (p<0.05). Metrics: Growth Parameter Assessment: Leaf length and width, stem diameter, chlorophyll content, and plant height were measured weekly for six weeks. Statistical Analysis: Fisher's Protected LSD test and post-hoc Tukey's test were utilized to identify mean differences between control and exposed groups. Conclusion: No significant differences were observed in the growth parameters between the control and exposed groups (p<0.05). Metabolomic Analysis: Metabolomic extraction was conducted immediately after the exposures concluded on the sixth day. A total of 24 samples, including 6 seed controls and 6 seed-exposed samples, were subjected to methanol-based metabolite extraction. High-performance liquid chromatography-mass spectrometry (HPLC-MS) was employed to identify and quantify metabolite features from collard and tomato samples, utilizing stearic acid and oleic acid as internal standards, respectively. The raw data obtained from the HPLC-MS analysis were analyzed using a Metaboanalyst software. Pathway and enrichment analyses revealed the identification of 140 compounds, which were grouped into metabolite pathways through hypergeometric analysis (p < 0.05). Linoleic acid metabolism emerged as the most highly expressed metabolic pathway (p < 0.00511) across all trials for both tomatoes and collards. Additionally, significant metabolites (p < 0.05) identified in both collards and tomato trials included C3H N3 O3 P2 and pantothenic acid, respectively. OPLS-DA score plots illustrated a distinct separation between the exposed and control groups for both collards and tomatoes in all trials. Metrics: Metabolite Extraction: Metabolomic extraction was performed on 24 samples. HPLC-MS Analysis: Identification and quantification of metabolite features were conducted using HPLC-MS. Pathway Analysis: 140 compounds were identified and grouped into metabolite pathways. Significant Metabolites: C3H N3 O3 P2 and pantothenic acid were identified as significant metabolites (p < 0.05). OPLS-DA Analysis: OPLS-DA score plots demonstrated clear separation between exposed and control groups for both collards and tomatoes in all trials. Transcriptome Profiling: RNA extraction was carried out on control and exposed tomato samples for subsequent RNA-sequencing analysis. Reads were mapped and aligned to a reference genome to identify known and novel gene transcripts. Differential gene expression analysis was performed by quantifying mapped reads, expressed as FPKM (fragments per kilobase of transcript per million mapped reads) values. In trials 1 and 2, both the control and exposed groups exhibited differential expression of genes, with 509, 434, 409, and 524 genes being differentially expressed, respectively. Notably, exposure led to the downregulation of five novel genes across both trials, including Solyc07g065840.2 (a heat shock protein), Solyc09g010630.3, Solyc01g099770.3, Solyc01g101060.3, and Solyc03g119080.3. Metrics: RNA Extraction: RNA extraction was performed on control and exposed tomato samples. RNA-Sequencing Analysis: Differential gene expression analysis was conducted by RNA-sequencing. Differential Gene Expression: Differential expression of genes was observed in both the the control and exposed groups. Downregulated Genes: Five novel genes were downregulated upon exposure in both trials.

We intend to create a manuscript or manuscripts based on fresh research findings. What do you plan to do during the next reporting period to accomplish the goals?Our objective is to finish the research for Andrea's thesis on this project and publish the research results. We are currently examining metabolomic data that indicates that collards and tomatoes have had a molecular response as a result of magnetic field exposure. In order to determine the genetic components involved in the magnetic field response in plants, we will correlate this response using transcriptome profiling.

Impacts
What was accomplished under these goals? We are currently analyzing data from metabolomic analyses. Our results confirm a significant change in plant metabolite expression in plant seeds exposed to magnetic fields. We expect to observe similar results from the pending transcriptome profiling analysis. The phenotyping analyses have shown no significant differences in plant traits and physical parameters ( chlorophyll content, stem width, plant height, leaf area index, etc.), thus; it appears that the significant effect on plant metabolite expression is occurring at the metabolome and potentially transcriptome levels. The magnetic field generator'(Helmholtz coils) cannot achieve magnetic field intensities higher than 4.7 Gauss, which explains the lack of physical differences between exposed and control groups. Therefore, future funding may be necessary to acquire a machine that produces magnetic fields at higher intensities. Regardless we are pleased to observe molecular effects due to magnetic field exposure as many metabolites with increased expression due to the magnetic fields are bioactive, nutraceutical compounds.

Year two studies involve transcriptome and metabolomic profiling studies, which are presently pending. We expect to have Year I results thoroughly analyzed as well as preliminary results from Year II.

      Impacts
      What was accomplished under these goals? According to a recent USDA-ERS report, Agriculture, food, and related industries contribute $1.053 trillion to U.S. gross domestic product (GDP) due in part to on-going developments in agrotechnology Innovations in animal and crop research that provide deliverables to farmers and stakeholders can increase Net farm income forecasted to increase $3.1 billion (3.3 percent) from 2019 to $96.7 billion in 2020. Biological, mechanical, chemical, and organizational innovations from both public and private sector investments in research and development (R&D) have primarily driven this productivity growth. Currently, of specific interest to producers, small-scale farmers and stakeholders are efficient, environmentally friendly crop propagation methods. The geomagnetic field (GMF) is a natural component of our environment. Krylov and Tarakonova (1960) were among the first to report on MF effects on plants. In 1963, it was reported that a magnetic field (MF) of relatively low intensity could be useful in stimulating or initiating plant growth responses (Pittman, 1963) Although, magnetic field exposure effects to stimulate growth are well-documented, the impact of geomagnetic field exposure effects in plants is poorly understood. Thus, a comprehensive understanding of magnetoreception dynamisms in plants necessitates new in-depth approaches.Our preliminary magnetic field exposure studies resulted in increased biomass production in different plant species. The goal of this USDA-funded research is to expose plant species of high-economic value to magnetic fields under specific intensities and duration and elucidate the resultant biological phenomenon. We endeavor to identify an MFE protocol that may enhance plant growth and development for farmers to increase efficacy in crop production. Furthermore, as the agriculture industry continues to grow, the need for skilled workers becomes a priority. A critical goal of this project is to provide experiential learning in new and emerging plant propagation and research techniques for University students incorporating the use of innovative tools, techniques, and equipment. Students are currently developed a website for the dissemination of existing research factoids and project results for stakeholders. Project Co-PI dutifully serves as mentors to enhance the professional development of the student research team. . Preliminary phenotyping of plant species under MFE - Senior Advisor and MFE Lead - Dr. S. Asundi. Plant breeding and Phenotypic assessment and Project Evaluation Lead: Dr. D. Mortley. Year I: Project activities included the installation of a beautiful research greenhouse ( Atlas Greenhouses) on July 26th, 2019, respectfully named the "G.W. Carver Phytoresearch Unit"(CPU) which has been utilized for project research providing a stable, controlled environment for critical plant breeding experiments and data collection. This resource has directly enhanced the University's agricultural research infrastructure ( GWC Ag. Exp. Station) and will serve as a foundation for future experiments in modern plant science. Additionally, students and PD ( Project Director) developed a micro research unit utilizing reclaimed wood and discarded materials housed within the CPU. During Year I, plant seeds, including carrot, collards, beets, kale, lettuce, swiss chard, and sweetpotato, were subjected to preliminary screening analysis as stated in Objective I. Plant seeds were exposed to baseline magnetic field frequency of 2.5 Gauss for up to 8 hr. After exposure, seeds were planted in the CPU by the student agricultural research team, who performed weekly physical measurements until harvest. The student team is responsible for daily monitoring of plants ( visual reports via WhatsApp 3x/daily), plant breeding and propagation, data collection and analysis, assistance in experimental design, website design, and are strongly encouraged to use critical thinking in all endeavors. Development of TU-ST.A.R.T (Tuskegee University Student Agricultural Research Team) program A significant amount of project funding was allocated to support student stipends during their participation in project research. Students have reported the installation of the CPU has increased their interest in agricultural research. The student participants were selected based on their academic backgrounds, which include a variety of disciplines, supporting the collaborative, interdisciplinary aim of this project. Students from plant and environmental sciences, computer science, and engineering were provided experiential training in innovative plant research and have become proficient in the use of a variety of modern data collection tools. Currently under construction is a website that will feature the student ag. Team, project results, and existing research factoids for farmers, producers, stakeholders, USDA, and governmental officials. The current St.A.Rs. of the St.A.R.T program are Team Captains: Alexandria Turner, ( UG, Plant, and Environmental Science, Data Collection and Analysis Lead), Team Captain Inocent Ritte (Experimental Design and Phenotypic Analysis Lead, ) Lieutenants: M.D. Chowdhury ( Website and Outreach design Lead ), Capri Charleston ( Metabolomics Lead, Outreach), Tia Archie ( Bioinformatics Lead), and Jacob Fitch ( Plant propagation, data collection, and interpretation). Additional Research (not stated in the awarded grant) Field trial collaboration with 4th generation small-scale farmers, Al Hooks, Al Hooks Family Produce, Shorter, AL. During the Summer of 2019, while the CPU was installed, Senior Advisor, Dr. Asundi, and the Project PD, collaborated with NRCS producer AL Hooks ( Al Hooks Produce) to initiate field trials of exposed and control plants. This opportunity provided participants with direct interaction with a local small-scale farmer and experiential learning in-field experimentation. Our collaboration may serve as a platform for future research to provide deliverables to farmers in the local community. 2018 TU Summer Camp for High School students The College of Ag. Env. and Nutr. Sciences have developed a "SMART-Camp" (R. Shange) program to engage high school students in various aspects of agriculture, including research and to promote professional development In 2018, before the project start date, a local high-school student assisted in an MFE trial on sweetpotatos. Sweetpotato varieties, including "Carver, Georgia Jet, and Nugget," were exposed to different time intervals of MFE for one week. Although not statistically significant, the results showed a small increase in sweetpotato root weights in exposed groups.
