"SuppressSOIL - Soil biodiversity and suppressiveness of soil against plant diseases and insect pests"
The project investigates microbiome and functional commonalities with respect to soil properties on a scale from soils with long-lasting intrinsic suppressiveness to soils where this disease resistance should be brought about mainly with specific agricultural management strategies.
The first approach is based on chromatographic soil profiling, quantification of soil diversity using metabarcoding techniques, and targeted monitoring of the totality of phytopathogens and insect pests. Suppressive and non-suppressive soils are also compared under controlled and free conditions. Another approach is based on experimental evaluation of a) the ability of suppressive soils to control large numbers of phytopathogens and insect pests, b) conditions of gene expression of biocontrol relevant genes of root-colonizing plant protectors, c) influence of arbuscular mycorrhizal fungi on suppressiveness.

The Jena Experiment
The Jena Experiment (DFG Research Unit 5000) is one of the longest-running biodiversity experiments in the world (running since 2002). The central aim of the Research Unit is to uncover the mechanisms that determine biodiversity-ecosystem functioning (BEF) relationships in the short- and in the long-term.
Subproject 1 - Mycorrhiza
"Microbial root symbionts as drivers of eco-evolutionary dynamics and long-term biodiversity-ecosystem functioning relationships in plant communities"
Given the main objective of the Research Unit, namely to uncover the mechanisms that determine BEF relationships in the short- and in the long-term, the main goal of SP1 is to elucidate the mechanisms driving biodiversity and community assembly of AMF along a plant diversity gradient. In particular, we ask whether the interplay between plants and AMF diversity changes over time, and could play a role in the expected reinforcement of the BEF relationship with time. Our subproject takes advantage of the long-term plant diversity gradient established in the Jena Experiment, including the nested experimental treatments to separate the time-related co-adaptation with plants (plant history) from the soil history effect. We broaden the study frame by considering additional soil fungal functional groups (sapro- and pathotrophs) in comparison to AMF. Specifically, this subproject will address the following questions:
1) Does ecosystem aging (history) correspond to co-adaptation between the fungal and plant partners of AM symbioses? e.g. Does this coadaptation result in selection of specialized AMF at low plant diversity, whereas generalist AMF are selected at high plant diversity levels?
2) Is this “partner optimization” related to symbiotic link improvement as reflected by enhanced mycorrhization rates?
3) Are co-adaptation and the related BEF relationship dependent on soil history, plant history, or both?
4) Are the observed dynamics specific to AMF or mirrored by other fungal functional groups?

RESCHEDULE - Collaborative Project: Increasing the resilience of Mediterranean agricultural systems to climate change extremes
- subproject
"Microbiome indicators of soil health for the development of model-based sustainable management strategies in the Mediterranean region"
The main objective of RESCHEDULE is to increase the sustainability and resilience to climate change and climate extremes of smallholder farms in the Mediterranean region by improving soil health. The specific objectives of RESCHEDULE stem from the current environmental challenges, gaps in knowledge and state of the art, and the need to contribute to the implementation of essential initiatives in the field of farming systems and in particular soil neutrality, the EU Farm to Plate initiative and the European Green Deals.
This subproject supports this objective through its expertise in soil microbial ecology, in machine learning based modeling, and also through its GCEF experimental field platform, which allows co-manipulation of climate and land use in the German driest region around Bad Lauchstädt. These research activities aim to causally explain the structure and function of the soil microbiome and the mechanisms of its adaptation to aridity and agricultural management, and from this to define knowledge-based indicators of soil health. From this knowledge, recommendations for sustainable management can be derived.

Subproject 2
“Analysis of the biodiversity and ecological functions of soil fungi and soil bacteria”
Networks of soil organisms and plants are key drivers of biogeochemical cycles in terrestrial ecosystems. Soil communities of fungi, bacteria, archaea, and other protozoa are important for functions such as C storage, tree resilience to climate change, and matter turnover in forest soils. There is a nationwide monitoring of tree vitality and soil physicochemical condition with the Soil Condition Survey in Forests (BZE). However, soil biology has not yet been considered. An extended systematic monitoring can help to understand relationships between site conditions, soil organisms and their functions. This project therefore aims to link the comprehensive data of the BZE with newly collected data on structural and functional biodiversity of soil microorganisms.

SPP - Rhizosphere
The Rhizosphere Priority Program aims at the identification of patterns in space and time in the volume of the soil affected by living roots, the rhizosphere. Its major goal is the explanation of the mechanisms behind and feedback processes between the soil, soil microorganisms and the plants during rhizosphere establishment. The overall hypothesis of the Priority Program is that resilience emerges from self-organized spatiotemporal pattern formation in the rhizosphere.
contributing project P8 - Root Genes I and II
“Spatial and temporal analysis of maize root gene expression patterns as a tool to elucidate how the maize interacts with rhizosphere microbiome and the environment”
The central aim of this associated project in frame of the SPP 2089 is to reveal mechanisms how maize roots adapt to changes in soil environment, and how the adaptations contribute to rhizosphere processes at a single root type and at root system levels. Based on the special importance of substrate, observed in the first phase, the project aims at a more precise understanding of the substrate induced changes in gene expression. It concerns soil compaction that is an important factor for agricultural production and. Carbon allocation that represents an important modifier of plant defense response and rhizosphere functioning, and is also related to maize gene expression. Our data suggest that the changes related to substrate and soil depth may be related to differences in soil moisture. Drought events are predicted to increase in frequency and intensity and cause a challenge for agricultural production, and this aspect is included to the research program. To address the impacts of substrate, soil depth and maize genotype at a higher scale, the annual development of the maize field is included in the frame of Complex Sampling among the participants of the priority program.

“Microbial life in the rhizosphere: kinetics and visualization of the functions”
The general objective of Microzym is visualization and quantitative analysis of biochemical processes in the rhizosphere enabling to link microbial functional traits with localized process rates in space and time.
Specific objectives:- Development and modification of methods for spatial analysis of distribution of root and of microbial activity parameters considering soil structure at the aggregate level. For this objective, the range of methods developed during first stage of PP (e.g., time-lapse zymography, oxidative zymography, micro-zymography, aminography) will be further extended (to e.g., oxidative micro-zymography, micro-aminography and amino-mapping) and localized micro-sampling at the level of individual aggregates will be applied for spatial and temporal identification of soil and root properties responsible for microbial activities and functions.
- Comparison of microbial feedback to unfavorable environmental conditions in the rhizosphere of two maize genotypes. For that, we aim to relate the localization of enzymatic activity with microbial growth parameters at the epi-centrum, at the boundary and outside the rhizosphere hotspots under limitation by nutrients and water.
- To reveal spatial specificity of organic substrates transformation and turnover at the rhizosphere – detritusphere interfaces as regulated by the rates of root detritus decomposition.
- To study a shaping effect of soil profile formation induced by maize monoculture on microbial and enzymatic functional traits in the rhizosphere.

The DFG joint research program SoilSystems aims to integrate a thermodynamic description of the soil system in order to gain a systemic view on energy and matter fluxes and their interactions with living and non-living soil components.

contributing project P5 - MICROHEAT
“Heat dissipation and matter turnover in the course of microbial succession constrained by substrate and oxygen availability”
Current challenge to increase sequestration of soil carbon (C) - the largest and most important terrestrial C stock - requires understanding the processes of carbon losses during microbial decomposition of diverse organic compounds, which serve as a substrate to obtain C, energy and nutrients for microbial metabolism.
The project Microheat considers that transformation of organic substrates in soil occurs in the course of multi-stage microbial succession through a sequence of decomposition stages. The methodological novelty and challenge of Microheat, therefore, is in estimation of the anaerobic soil volume fraction via application of X-ray CT to study the effect of oxygen diffusion constraints on C and energy use efficiency (CUE and EUE). The peculiarity of Microheat is in its conceptual view linking matter (CO2) and energy (heat) losses to microbial growth and to the range of enzyme-mediated reactions related to various stages of substrate decomposition. The Microheat project will make a promising contribution to elucidating regulatory mechanisms of energy and matter turnover based on the microbial trade-offs between rate and efficiency of organic compounds decomposition in soil.

“A drought tolerant synthetic bacterial community for barley”
Drought events will increase in frequency and intensity and thus increasingly become a challenge for agricultural production. It is well known that plants respond to drought with changes in the plant-associated microbiome, and the adapted microbiome can thus contribute to increasing plant fitness. The proposed project investigates interaction mechanisms between synthetic bacterial communities and barley under drought stress. Bacterial and plant gene expressions, as well as measurements of barley drought tolerance, will be the focus.

- “SpOC - Temporal and spatial dynamics of organic carbon in intermittent springs – Environmental drivers and connectivity to headwater streams”
Springs are the birth of headwater streams. They represent the starting point of the river continuum, and are important ecotones between groundwater and surface water. Intermittent springs originate from near-surface, unconfined aquifers. They display a temporarily groundwater disconnected flow regime, short residence times and may act as sources of organic carbon (OC) to headwater streams. As a result, intermittent springs have the potential to significantly impact carbon fluxes in headwater streams. However, only a few eco-hydrological studies have addressed springs as distinct sources of OC, and it is still unclear how the variable flow regime impacts the temporal variability or organic carbon in these diverse ecotones, which are typical for low mountain ranges. Therefore, the objective of this proposal is to investigate the spatial and temporal dynamics of OC in intermittent springs, environmental drivers of these processes, and their downstream impact in different low mountain ranges. This cross-scale study of the hydrological and biogeochemical properties of intermittent spring and their spatial and temporal dynamics will close the existing knowledge gap regarding the role of intermittent springs within the river continuum concept. This would further contribute to the understanding of potential shifts in the dynamics of springs due to climate change induced variations in precipitation and runoff, and the impact of their changes on both the spring ecosystem, as well as related headwater streams
