Non Technical Summary
This collaborative program addresses two contemporary issues that focus on human alterations of the soil ecosystems: 1) the consequences of predicted climate change patterns (variability in precipitation and extreme drought events) on soil microbial communities and 2) the optimal fire frequencies in the Piedmont National Forest (GA) for maintaining soil microbial communities and their function. The program takes advantage of the recent, rapid development of the high throughput DNA sequencing that permits unprecedented interrogation of the microbial communities - their species richness, biodiversity as well as community composition. The microbial community analyses are tied to function of the soils by evaluation of the realized microbial activities through analyses of the carbon and nitrogen modifying enzymes that these communities produce. These approaches generate data to estimate the impacts of predicted climate change scenarios on soil microbial communities and to optimize fire management regimes in southeastern forest systems to maintain desirable aboveground communities that support secondary forestry products such game species. These research components provide information on soil responses to management and environmental change for scientists and researchers, serve land managers to optimize land management strategies, as well as guide policy makers on soil systems and their responses to human management and environmental alterations.

Goals / Objectives
Collaborative components included here aim to identify the consequences of predicted climate change patterns (variability in precipitation and extreme drought events) on soil microbial communities. Collaborative components included here aim to determine the optimal fire frequencies in the Piedmont National Forest (GA) for maintaining soil microbial communities and their function.
Project Methods
Consequences of predicted climate change patterns on soil microbial communities. Climate change models predict that future precipitation patterns will entail lower frequency but larger rainfall events, increasing the duration of dry soil conditions. The proposed studies will utilize infrastructure and resources at the Konza Prairie Biological Station (KPBS, 39?05' N, 96?35' W) Long-Term Ecological Research (LTER) site representative of native tallgrass prairie. Collaborative arrangements with Dr. John Blair permit the use of Rainfall Manipulation Plots (RaMPs) established in 1997 and comprised of twelve sheltered RaMPs. Each RaMP is a fixed-location, 14 x 9 m rainout shelter over intact, native grassland with a clear (UV transparent) polyethylene roof to exclude natural rainfall, two 4 m3 reservoirs to collect and store to up to 10 cm of rainfall, and an overhead irrigation system to reapply (at 2.5 cm hr-1) the stored rainfall. This design allows for efficient experimental control of the quantity, timing, and variability in rainfall inputs during the growing season (April - Oct), when > 75% of the annual precipitation falls. The current rainfall timing treatments (ambient or altered timing) receive 100% of ambient rainfall quantities, but the RaMPs assigned to the altered precipitation regime receive rainfall inputs in intervals between rainfall events lengthened by 50%. The treatments will be modified starting in the 2013 or 2014 growing season to include more extreme droughts. The project will utilize and analyze DNA extracted from soil samples to evaluate microbial community responses. For each experimental unit, genomic DNA will be extracted from a 10 g subsample (UltraClean Mega Soil DNA Kit, MoBio, Carlsbad, CA) and stored at -80°C. Microbial communities will be analyzed via high throughput sequencing of PCR-amplicons generated with primers targeting either bacterial 16S ribosomal RNA (rRNA) gene or fungal Internal Transcribed Spacer (ITS) of the rRNA gene as we have done before. Sequences will be analyzed using bioinformatics analysis package mothur to determine the microbial community composition. Estimates for microbial community richness, diversity and compositional constituents will be generated in mothur and compared using standard statistical inference tools as we have done previously to evaluate the differences among the treatments. The soil functional attributes will be estimated using a fluorimetric, 96-well plate assay as we have done previously in different systems. 2) Optimal fire frequencies in the Piedmont National Forest for soil microbial communities and function. Prescribed fire is a forest management tool across the southeastern United Statesand provide an economical way to manage stands primarily comprised of economically important timber species. The proposed activities rely on collaboration with Dr. Mac Callaham and will utilize the infrastructure and resources located in the Hitchiti Experimental Forest, GA (32º58'N, 90º44'W). The long-term prescribed fire experiment was established in the winter of 1988/1989 when all plots (except the unburned controls) were burned with low intensity backfires and prescribed fire reapplied with different return intervals (2r, 3 yr, and 6 yr) or left unburned (control). Each treatment is replicated in a total of four ~0.8 ha plots. From the established long-term experiment, we will sample fifteen random soil cores, bulk them into one per each plot, store frozen until further processing. The pooled core samples will be thawed at room temperature, thoroughly homogenized and passed through a 1mm mesh sieve to remove rocks, large particles, and roots. Genomic DNA will be extracted from a 10-g aliquot (UltraClean Mega Soil DNA Kit, MoBio, Carlsbad, California) for high throughput sequencing like described above. The functional attributes will be estimated using a fluorimetric, 96-well plate assay (Marx et al. 2001, Rigdon et al 2013) following the approach outlined above.

Outputs
Target Audience:During this reporting period, we have continued progress on assessing human and management effects on microbial communities in soil or those associated with plants. Our deliverables primarily target scientific community (students, scientists and researchers) but the more applied components benefit also policy makers, extension service personnel, and land managers. We have addressed target audiences 1) in scientific meetings (American Geophysical Union 2018 Meeting; Annual oSTEM Conference; 11thInternational Mycological Congress), 2) through publications (Freshwater Science), and 3) less informally through our collaboration with USDA Forest Service, agricultural extension service personnel, and students and visiting faculty, who received training in Jumpponen's laboratory. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Jumpponen recruited one new graduate student in addition to two recruited under the previous reporting period.These three students are engaged in experimental design, experimental execution and data analyses. Two of the students focus on effects of fire manipulations in forested or grassland systems, third aims to answer questions about fungal ecotypic adaptions to drought. During the evaluation period this project has served to train one visiting junior faculty. The training focused on dissecting microbiomes in crop grasses. Finally, this program has created personal development opportunities for local undergraduate (2) and graduate students (4), who conduct their independent research projects and have networked with peer scientists to generate and analyze environmental data. How have the results been disseminated to communities of interest?We have disseminated our research findings in professional meetings locally (Division of Biology Graduate Student Forum; Kansas State University Graduate Student Forum; Research and State:15thCapitol Graduate Research Summit), nationally, and internationally (11thInternational Mycological Congress). Additionally, we have been active in publishing and list those contributions under the "Products" Section. During this reporting period wehave continued ourcollaborationwiththe USDA Forest service to generate data to address short- and long-term microbial community responses to fire. These contacts have also provided avenues for less formal dissemination of our research outcomes. Finally, we continue our engagement of undergraduate and graduate students in the laboratory by providing students unique opportunities to conduct primary research.? What do you plan to do during the next reporting period to accomplish the goals?We remain committed to disseminate our findings to various audiences. To do this, four graduate students and a minimum of one undergraduate will present their independent research at the Mycological Society of America Meeting in Minneapolis, MN, in August, 2019.We are currently preparing two manuscripts on microbiomes of foundation and crop grasses as well as two on ecotypic adaptation of fungi to drought. Additionally, we continue to generate vast volumes of data and continue to improve our protocols and pipelines to expedite data generation/analyses. We have built protocols on libraries of "batch commands" that permit automated data analysis streams and can be expediently applied to generated sequence data. We maintain funding to continue on microbial community responses to environmental change in phytobiomes of dominant, keystone grasses, and microbiome recruitment and establishment in the biofuel grasses (Miscanthus and Panicum).

Impacts
What was accomplished under these goals? We completed analyses of data on grass microbiomes in the Great Plains and continue preparing publications in collaboration with students and faculty from Kansas State University and University of New Mexico. Fungi chosen to represent potentially drought tolerant isolates from collaborator's culture collection housed at Western Illinois University were exposed to drought in vitro and in planta. First analyses of these data suggest little evidence for ecotypic drought adaptation in fungal communities. However, many fungal strains are able to improve plant survival under drought conditions and productivity under increased temperatures. Under the second major goal of the project, we have successfully completed the fruitful collaboration with the USDA Forest service and generated data to describe soil community responses to prescribed fire manipulations that have been consistently maintained for more than half a century.

Our deliverables primarily target scientific community (students, scientists and researchers) but the more applied components benefit also policy makers, extension service personnel, and land managers. We have addressed target audiences 1) in scientific meetings (Evolution 2017; Joint Meeting of the Missouri and Missouri Valley Branches of the American Society of Microbiology; Annual oSTEM Conference; American Phytopathological Society; Annual Ecological Genomics Symposium; Annual Meeting of the American Society of Agronomy), 2) through publications (Forest Ecology and Management; Molecular Ecology), and 3) less informally through our collaboration with USDA Forest Service, agricultural extension service personnel, and students, visiting post-doctoral associates, and visiting faculty, who received training in Jumpponen's laboratory. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Jumpponen recruited two new graduate students and has trained two undergraduate students in his laboratory. Two additional students are currently being recruited to join the laboratory during 2018-2019 academic year. These students will have been trained and engaged in experimental design, experimental execution and data analyses. During the evaluation period this project has served to train visiting and local faculty/students. These training collaborations include research programs that focus on microbiomes in foundation and crop grasses, and microbial community dynamics under different experimental manipulations. Finally, this program has created personal development opportunities for local undergraduate (2) and graduate students (2), who networked with peer scientists to generate and analyze environmental data. How have the results been disseminated to communities of interest?In the course of the project activities, we have disseminated our research findings in professional meetings locally (KSU Ecological Genomics Forum, Division of Biology Graduate Student Forum), nationally, and internationally (Annual Meeting of the American Phytopathological Society).

Finally, we continue our engagement of undergraduate and graduate students in the laboratory by providing students unique opportunities to conduct primary research. What do you plan to do during the next reporting period to accomplish the goals?We continue to generate vast volumes of data and streamline protocols and pipelines to expedite. We utilize libraries of "batch commands" that permit automated data analysis streams and can be expediently applied to generated sequence data. We maintain funding to continue on microbial community responses to environmental change in phytobiomes of dominant, keystone grasses, and microbiome recruitment and establishment in the biofuel grasses (Miscanthus and Panicum). In the course of the next reporting period, we aim to continue reporting and publishing in peer reviewed journals and professional meetings. We plan to attend the International Mycological Congress in 2018 to describe our ongoing research.

Impacts
What was accomplished under these goals? We completed data generation of data characterizing host microbiomes in the Great Plains and continue analyses of these data in collaboration with students and faculty from Kansas State University and University of New Mexico. Preliminary data from drought manipulation experiments suggest that while there are some host specific responses, the host-associated microbiomes are universally responsive to drought. These data are currently used to choose potentially drought tolerant isolates from collaborator's culture collection housed at Western Illinois University to evaluate their use as drought-modulating synthetic microbiomes. Under the second major goal of the project, we have expanded the fruitful collaboration with the USDA Forest service and initiated a new program to evaluate microbial community and functional responses to recurring prescribed fires that have been consistently maintained for more than half a century.

Outputs
Target Audience:During this reporting period, we continue progress on the project focusing on human and management effects on microbial communities in soil and those associated with plants. Our program deliverables mainly target scientific community (scientists and researchers) but the more applied components benefit also policy makers, extension service personnel, and land managers. We have addressed target audiences 1) in (inter-)national scientific meetings (Annual Meeting of the American Phytopathological Society, Annual Ecological Genomics Symposium, Florida Genetics symposium, European Geosciences General Assembly, 16th International Society of Microbial Ecology Meeting; 2) through publications (Microbial Ecology, International Journal of plant Sciences, Phytopathology, Forest Ecology and Management, Frontiers in Ecology and Evolution), and 3) less informally through our collaboration with USDA Forest Service, agricultural extension service personnel, and students/visiting post-doctoral associates and faculty who received training in Jumpponen's laboratory. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?We continued addressing the research questions and experiments established under this program in an undergraduate student classes. In collaboration with faculty in agriculture (Charles W. Rice and DeAnn Presley) and with extension appointments (DeAnn Presley), we have designed and executed experiments to evaluate the use of microbial inocula for winter wheat. Jumpponen also recently recruited two new graduate students and maintained three undergraduate students who participated in research under this project. These students in the program leader's laboratory have been engaged in experimental design, execution and data analyses. During the evaluation period this project has served to train visiting and local students and visiting faculty representing both local and national research groups. These loose training collaborations include research programs that focus on microbial pathogens in living environment, recruitment and establishment of microbiomes in foundation and crop grasses, and community dynamics under different experimental manipulations. Finally, this program has created personal development opportunities for local undergraduate (3) and graduate students (3), who networked with peer scientists to generate and analyze environmental data. 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?We continue to generate vast volumes of data and adopt new protocols as well as pipelines to expedite and streamline data generation and analyses. We have generated libraries of "batch commands" that permit automated data analysis streams and can be expediently applied to generated sequence data. We maintain funding to continue on microbial community responses to environmental change in phytobiomes of dominant, keystone grasses; and have also secured additional funding to dissect microbiome recruitment and establishment in the biofuel grass Miscanthus and will target the microbiomes of that host in due course. We will acquire additional personnel to complete fieldwork as well as to generate and analyze high throughput sequencing data. In the course of the next reporting period, we aim to continue reporting and publishing in peer reviewed journals and professional meetings. We plan to attend the Ecological Society of America in 2017 to describe our phytobiome research.

Impacts
What was accomplished under these goals? We continued to generate and analyze data from our project focusing on the soil and host microbiomes in the Great Plains. These datasets inform management decisions on public and private lands and record the biodiversity in these systems. In the course of these activities we have also participated in statistical tool development - specifically network analyses. The latter effort has been published in Phytopathology, whereas the results from the former continue to be analyzed. Under the second major goal of the project, we have continued the fruitful collaboration with the USDA Forest service and reported fast and distinct community responses to fire - now published in Forest Ecology and Management.

In collaboration with faculty in agriculture (Charles W. Rice and DeAnn Presley) and with extension appointments (DeAnn Presley), we have designed experiments to evaluate the use of microbial inocula for major crops. These experiments are currently underway and will be analyzed undergraduate students enrolled in BIOL604 - Biology of Fungi. Jumpponen also recently recruited three new undergraduate students to participate in research under this project. These students in the program leader's laboratory have already been engaged in sequence data analyses. During the evaluation period this project has served to train students, post-doctoral fellows, and sabbatical faculty from other laboratories and research groups locally, nationally and internationally. These loose training collaborations include research programs that focus on urbanization, microbial pathogens in living environment, and community dynamics and succession during composting. Finally, this program has created personal development opportunities for local undergraduate (3) and graduate students (3), who networked with peer scientists to generate and analyze environmental data. How have the results been disseminated to communities of interest?In the course of the project activities, we have disseminated out research findings in professional meetings locally (KSU Ecological Genomics Forum, Division of Biology Faculty Data Blitz) regionally (Annual Meeting of the Kansas Academy of Science, Midwest Organic Farming And Sustainable Education Service Meeting), nationally, and internationally (Annual Meeting of the American Society of Agronomy, Annual Meeting of the American Phytopathological Society, International Conference on Mycorrhizae, Phytobiomes 2015: Designing a New Paradigm for Crop Improvement). Additionally, we have been active in publishing and list those contributions under the "Products" Section. During this reporting period we ahve also engaged faculty in agriculture, entomology, horticulture, and plant pathology as well as faculty with extension service appointments to continue applied research on management impacts. Less formal dissemantion has taken place through our collaboration with USDA Forest Service and students/visiting post-doctoral associates who received training in Jumpponen's laboratory. Finally, we continue our engagement of undergraduate students in the laboratory by providing students unique opportunities to condict primary research. Further, we continue to engage REU (Research Experiences for Undergraduates) and URM (Undergraduate Research Mentoring) students in presentations and through personal contact. What do you plan to do during the next reporting period to accomplish the goals?We continue to generate vast volumes of data and adopt new protocols as well as pipelines to expedite and streamline data generation and analyses. We have secured additional funding to continue on microbial community responses to environmental change in phytobiomes of dominant, keystone grasses. We will acquire additional personnel to complete fieldwork as well as to generate and analyze high throughput sequencing data. Additionally, we have secured funding to continue research on fire dynamics and will generate and analyze additional data on these as well. In the course of the next reporting period, we aim to continue reporting and publishing in peer reviewed journals and professional meetings. We plan to attend the International Society of Microbial Ecology Conference in 2016 to describe our phytobiome research as well as to present posters on the fire management in the Mycological Society of America meetings.

Impacts
What was accomplished under these goals? Previously we generated several next-generation sequencing datasets on environmental change with ancillary datasets from experiments on prescribed burning and woody encroachment removal in the grassland ecosystems. These experiments aim to elucidate the effects of management choices on soil-inhabiting and root-colonizing fungi. Previously completed datasets have been published in Forest Ecology and Management and in FEMS Microbiology Ecology, respectively. These datasets inform management decisions on public and private lands. An additional, technology evaluation contribution focusing polymerase choice in environmental analyses was recently published in Fungal Ecology highlighting the importance of using a "proof-reading" enzyme in generating environmental datasets. While this protocol evaluation was rather minor, it has been already highlighted as "Hot Paper" and "Highly Cited Paper" in Thomson Reuter's Web of Science. In the course of the current evaluation period, we also actively sought funding to expand the fire management research. We have successfully secured two projects: 1) a direct continuation of the effort in Piedmont National Forest in Florida and 2) a new project with focus on comparing the effects of burn intensity on the soil fungal communities.

Target Audience: During the 2014 reporting period, the project generated data on human effects on microbial communities in soil or associated with plants. These deliverables targeted primarily scientists and researchers, but also policy makers and land managers. These target audiences were addressed 1) in scientific meetings (American Society for Horticultural Science Annual Conference, DOE Genomics Grantee's Meeting, Annual meeting of the International Society of Microbial Ecology, Annual meeting of the Mycological Society of America, Ecological Genomics Symposium, Joint Meeting of the American Phytopathological Society and the Canadian Phytopathological Society), 2) through publications (Fungal Ecology, Frontiers in Microbiology, Mycorrhiza), and 3) less informally through our collaboration with USDA Forest Service and students who received training in Jumpponen's laboratory. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? The lessons learned from this program were utilized in lectures used in two undergraduate student classes: Microbial Ecology and Biology of Fungi. Further, graduate students in the program leader's laboratory were engaged in broad collaborations that transfer their experiences in sequence data analyses to other laboratories and research groups locally, nationally and internationally. This program also created personal development opportunities for local undergraduate and graduate students, who networked with peer scientists to generate environmental data and analyzed those data. How have the results been disseminated to communities of interest? In the course of these activities, we have disseminated our findings in professional meetings nationally (American Society for Horticultural Science Annual Conference, DOE Genomics Grantee's Meeting, Annual meeting of the International Society of Microbial Ecology, Annual meeting of the Mycological Society of America, Ecological Genomics Symposium, Joint Meeting of the American Phytopathological Society and the Canadian Phytopathological Society), in peer-meetings locally (KSU Ecological Genomics Forum, Faculty Data Blitz). Some results have been published as show above in "Products" section. Additionally, these activities have been highlighted locally to undergraduate students (Research Experiences for Undergraduates, REU, Summer Seminar Series). What do you plan to do during the next reporting period to accomplish the goals? The program continues to generate vast volumes of data. The goal for the reporting period 2015 is to continue data analyses and reporting in peer reviewed journals and professional meetings. We plan to attend the International Conference on Mycorrhizae in 2015 to describe our endophyte realted work as well as to present posters on the prescribed burning program.

Impacts
What was accomplished under these goals? We generated several next-generation sequencing datasets with ancillary environmental datasets for the climate change and prescribed burning to elucidate the effects of recurring prescribed burning on soil-inhabiting and root-colonizing fungi. Two of these datasets are completed and additional ones await further analyses. The first of these described the importance of polymerase choice in environmental analyses (manuscript is currently evaluated for publication in Fungal Ecology); the second describes broadly soil-inhabiting community responses to prescribed burning (Manuscript is currently under evaluation for publication in Forest Ecology and Management). These data were also presented in the Annual meeting of the Mycological Society of America. These datasets inform prescribed burning decisions on public and private lands.
