Genomic Research on Barley Wild Relatives: A Report on Contributions to Sustainable Development Goals
Advancing SDG 2 (Zero Hunger) through Enhanced Crop Resilience and Sustainable Agriculture
An international research initiative has made significant strides in enhancing food security by exploring the genetic diversity of wild crop relatives. This work directly supports the objectives of SDG 2 by aiming to improve agricultural productivity and create more resilient food systems.
- Objective: To harness genetic traits from the wild barley relative, Hordeum bulbosum, to improve the yield, resilience, and stress tolerance of cultivated barley (Hordeum vulgare).
- Key Achievement: Researchers successfully decoded the structure of the Ryd4 resistance locus, a genetic segment introgressed from H. bulbosum into cultivated barley.
- Impact on Food Security: The Ryd4 locus provides robust resistance to the barley yellow dwarf virus, a devastating pathogen affecting multiple cereal crops. Deploying this trait in commercial varieties can prevent significant crop losses, thereby strengthening global food supply chains.
- Future Breeding: The development of reference genomes for this wild relative enables more targeted introgression breeding, accelerating the creation of climate-resilient and higher-yielding crop varieties.
Supporting SDG 15 (Life on Land) by Conserving and Utilizing Genetic Diversity
The study underscores the critical importance of conserving terrestrial ecosystems and their genetic resources, a core target of SDG 15. By systematically characterizing wild species, the research provides a foundation for their sustainable use and protection.
- Collection and Analysis: A diverse panel of 263 Hordeum bulbosum genotypes was compiled from natural Mediterranean populations and existing genebank accessions.
- Genomic Characterization: The team successfully assembled and annotated 10 reference-quality, chromosome-scale genomes of this vital wild species, documenting its unique evolutionary path and genomic structure.
- Conservation and Accessibility: This foundational research transforms genebanks from passive seed stores into active biodigital resource centers.
- Sustainable Utilization: Making detailed genomic information of wild relatives accessible allows breeders to better utilize plant genetic resources for crop improvement, ensuring biodiversity is not just preserved but actively contributes to sustainable development.
Leveraging SDG 9 (Innovation) and SDG 17 (Partnerships) for Scientific Advancement
The success of this research was built upon scientific innovation and global collaboration, reflecting the principles of SDG 9 and SDG 17. The project highlights how advanced infrastructure and international partnerships are essential for addressing complex global challenges like food security.
- Technological Innovation (SDG 9): The project overcame previous technological limitations by employing recent advances in high-throughput genomic tools, allowing for an unprecedentedly detailed analysis of complex plant genomes.
- International Partnership (SDG 17): The research was led by the IPK Leibniz Institute and involved a global team of scientists, including members of the German Centre for Integrative Biodiversity Research (iDiv), demonstrating a successful model of international cooperation for achieving common goals.
- Building Resilient Infrastructure (SDG 9): The creation of reference genomes and the evolution of genebanks into biodigital resource centers represent an investment in resilient scientific infrastructure that will support future agricultural innovation.

Specific SDG Targets
SDG 2: Zero Hunger
-
Target 2.4: By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production.
Explanation: The research aims to improve barley by harnessing traits from its wild relatives to enhance “yield, resilience, and stress tolerance.” The development of resistance to the “devastating barley yellow dwarf virus” is a direct implementation of a resilient agricultural practice to ensure sustainable food production. -
Target 2.5: By 2020, maintain the genetic diversity of seeds, cultivated plants and farmed and domesticated animals and their related wild species, including through soundly managed and diversified seed and plant banks at the national, regional and international levels.
Explanation: The article is centered on this target. The research involves collecting “H. bulbosum genotypes from natural populations” and using “genebank accessions.” The work of the IPK Leibniz Institute to systematically characterize wild relatives and evolve the “genebank from a seedstore into a biodigital resources centre” directly contributes to maintaining and utilizing genetic diversity.
SDG 15: Life on Land
-
Target 15.6: Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed.
Explanation: The article highlights the goal of making “plant genetic resources better accessible for crop improvement.” By creating reference genomes and evolving the genebank into a “biodigital resources centre,” the research facilitates broader access to the genetic information derived from wild relatives like H. bulbosum.
Indicators for Measuring Progress
Indicators for SDG 2 Targets
-
Implied Indicator for Target 2.5 (Indicator 2.5.1: Number of plant and animal genetic resources for food and agriculture secured in conservation facilities):
Explanation: The article provides specific numbers that can be used as indicators of progress. It mentions the compilation of a “diverse panel of 263 genotypes” and the successful assembly of “10 reference-quality, chromosome-scale genomes” of the wild species. These numbers quantify the genetic resources that have been secured, analyzed, and made available for research and breeding.
Indicators for SDG 15 Targets
-
Implied Indicator for Target 15.6 (related to access and benefit-sharing frameworks):
Explanation: While not a formal indicator, the creation of “reference-quality, chromosome-scale genomes” and the transformation of the genebank into a “biodigital resources centre” serve as a practical measure of promoting access. The successful decoding of the “Ryd4 resistance locus” is a tangible benefit arising from the utilization of these genetic resources, demonstrating the value of this access.
