Presentation Overview: Show
Understanding plant stress responses requires integrating complex, dispersed knowledge on molecular
interactions into queryable, reusable resources. Stress Knowledge Map (SKM; skm.nib.si) addresses this
by consolidating curated information on protein-protein interactions, transcriptional regulation, small
RNA-transcript interactions, and enzymatic transformations in Arabidopsis thaliana. An additional
workflow integrating multiple lines of evidence supports translation of this information to crop species
including potato, tomato, and fruit trees. Together with associated analysis and modelling tools, SKM
supports systematic contextualisation of multi-omic data and the development of dynamic systems biology
models of stress signalling.
ELIXIR community activities have been central to SKM's growth and dissemination. The implementation
study "Increasing Plant data findability and reuse beyond ELIXIR" improved the accessibility and
interoperability of plant knowledge resources across the plant sciences. At the de.NBI BioHackathon
Germany 2023, SKM was indexed in FAIDARE, increasing its findability within the ELIXIR plant data
infrastructure. An ELIXIR Plant Sciences Community staff exchange extended SKM further, enabling a
BioChatter-based prototype for LLM-accessibility to lower barriers for experimental biologists.
These developments revealed a broader need: standardised, reusable infrastructure for transforming
systems biology models (in SBGN-ML and SBML formats) into human- and AI-accessible knowledge graphs.
This motivated the ELIXIR Systems Biology Community's project at the 4th BioHackathon Germany (December
2025), which produced an initial common labelled property graph schema grounded in a standard ontology
(SBO), SBGN and SBML BioCypher adapters, and initial support for SBML export - laying the groundwork for
a community-wide framework and future AI integration across systems biology.

Presentation Overview: Show
The ELIXIR Systems Biology Community has contributed to making Systems Biology (SB) research more
Findable, Accessible, Interoperable, Reusable (FAIR). Through the SYBEL project, we mapped connections
between researchers and essential tools/data resources, demonstrating that access mechanisms are as
vital as the resources themselves for enabling reproducible research.
Building on this foundation, we are synthesizing FAIR and CURE (Credible, Understandable, Reproducible,
Extensible) principles into actionable guidelines for the community. This translates into curated
FAIRsharing collections documenting standards and databases, bio.tools collections cataloging essential
software, and a RDMKit page providing practical implementation guidance. These resources directly
leverage ELIXIR Recommended Interoperability Resources and Core Data Resources, exemplifying how
Community activities enhance the value of ELIXIR.
Looking forward, we are exploring how artificial intelligence (AI) and knowledge-graphs (KGs) can
transform SB workflows. AI-assisted curation can accelerate development and annotation of models and
datasets, improving efficiency and consistency. KGs enhance data integration across heterogeneous
sources, making complex data more accessible. For modeling workflows, AI tools can ease accessibility to
datasets, suggest appropriate formalisms, validate model structure, propose mechanistic hypotheses
grounded in literature, and contribute to enhanced interpretability and explainability of SB models. In
a broader sense, AI-enabled data-driven models provide a synergistic complement to fundamental
knowledge-based SB models.
This evolution from merely exploring FAIR resources to AI-enhanced models/data resources represents the
Community's commitment to reducing barriers in SB research. By combining robust data management
practices with emerging AI capabilities, we aim to accelerate discovery, while maintaining the rigor
essential for reproducible SB.

Presentation Overview: Show
Plants enter a defensive state in response to environmental stresses or pathogens, rerouting many
resources from their primary growth objective and thus performing well below their maximum potential.
Understanding such trade-offs can help us develop improved crop varieties with increased stress
tolerance, improving yields and quality. As potato is among the most important food crops and a model
tuber crop species, it is of interest to establish it also as a model system for studying growth-defence
trade-offs.
To investigate growth-defence trade-offs in the context of metabolism, we developed a compartmentalised
genome-scale metabolic model of potato metabolism, Potato-GEM. It contains information on the
stoichiometry of over 7,000 biochemical reactions, connecting them to the genes encoding the enzymes
that catalyse them. We also curated and expanded the Potato-GEM secondary metabolism, capturing its full
extent according to the MetaCyc database. The potato leaf biomass was quantified using in-house and
published experimental data.
We employed the model to explore growth-defence trade-offs using transcriptomics data of biotic stress
responses to the pathogens Potato virus Y and pest Colorado potato beetle. This revealed the general
principles of stress induced growth-defence trade-offs and enabled the comparison of micro- and
macro-biotic stress response mechanisms. We thus demonstrate how the curated model can be used to
investigate multi-reaction trade-offs across primary and secondary metabolism, by integrating and
interpreting omics data. This provides the basis for a metabolic perspective on trade-offs and biotic
interactions typical across many plant species.
