Agricultural practices today face mounting challenges: increased environmental stressors, climate change impacts, and a heavy reliance on chemical fertilizers. A new, interdisciplinary project—the Wheat Alliance—aims to address these challenges by exploring the genetic factors in wheat that enhance its relationship with soil microbes. By strengthening wheat’s natural capacity to thrive with beneficial soil bacteria and fungi, the project seeks to improve nutrient uptake, reduce reliance on chemical fertilizers, and pave the way toward sustainable, resilient crop production systems.

Funded by a £5.6 million (DKK 50 million) grant from the Novo Nordisk Foundation, the Wheat Alliance is a collaboration among leading research institutions including Aarhus University, Copenhagen University, Utrecht University, North Carolina State University, NIAB, and the Crop Science Centre in Cambridge. This three-year initiative, led by Professor Simona Radutoiu of Aarhus University, is set to transform how wheat interacts with its surrounding soil microbiome, enhancing the plant’s performance under various environmental stresses.

Why Wheat-Microbe Interactions Matter

Environmental stressors—such as nutrient deficiency, drought, heat, flooding, pests, and disease—account for over a third of all crop losses worldwide. Meanwhile, studies show that the soil microbiome plays a crucial role in helping plants absorb nutrients and withstand stress. However, while we understand much about these microbe-plant interactions, the role of plant genetics in selecting beneficial microbes remains largely uncharted. The Wheat Alliance project addresses this gap by focusing on wheat genetics and its influence on microbiome interactions.

Dr. Kostya Kanyuka, Head of Plant Pathology at NIAB, highlights that modern wheat varieties are often bred for high-input systems, relying on chemical fertilizers and possibly lacking the genetic traits needed to optimize natural soil interactions. The Wheat Alliance project, therefore, presents an opportunity to identify and develop these genetic traits, promoting wheat that can thrive with reduced chemical inputs.

Building a Platform for Sustainable Wheat Production

The Wheat Alliance team, comprising experts in wheat genetics, plant-microbe interactions, and advanced data analysis, aims to create a platform for identifying the genetic components that help wheat form beneficial associations with soil microbes. This platform will support sustainable plant nutrition, reducing dependence on chemical fertilizers and supporting yields in low-input farming systems.

Professor Radutoiu explains, “By combining expertise in wheat genetics from NIAB with microbiome analysis and modeling at CCRP, we’re bringing together a unique set of resources. This focused collaboration will help unlock wheat’s genetic potential to harness the benefits of soil microbes, which is a promising step toward more sustainable agricultural practices.”

Harnessing the Power of Genetics and Technology

A key aspect of the Wheat Alliance project is large-scale screenings that will uncover the genetic constraints affecting wheat’s interaction with the soil microbiome. Using advanced phenotyping techniques and AI-driven data analysis, researchers will study how different wheat genotypes respond to nutrient limitations and identify those that form beneficial partnerships with soil microbes.

By developing predictive models based on this data, the team can identify wheat varieties that promote beneficial microbial partnerships. These findings could lead to the creation of bioinoculants tailored to support wheat growth, further reducing the need for chemical inputs.

Dr. Kanyuka elaborates, “Our wheat pre-breeding and genetics research at NIAB, which includes introducing genetic diversity from wheat’s close relatives, will underpin this project. We have thousands of new wheat lines available for genetic analysis, providing a strong foundation for identifying varieties that can benefit from microbial partnerships.”

Toward a Microbiome-Based Breeding Framework

The Wheat Alliance project’s ultimate goal is to develop a basic framework for microbiome-based breeding, which could inform future breeding programs not only for wheat but for other crops as well. This framework could enable breeders to select crop varieties that are naturally more resilient and nutrient-efficient, reducing the need for chemical fertilizers and enhancing sustainable agriculture.

Professor Radutoiu envisions a future where microbiome-based breeding becomes a standard approach for creating crop varieties better suited to low-input systems. “Our vision is to create a framework that provides key information to breeders, enabling them to implement this approach across crops and reduce agriculture’s reliance on chemical inputs,” she states.

Paving the Way for Resilient and Sustainable Agriculture

The Wheat Alliance project marks a significant step forward in sustainable agriculture. By uncovering the genetic elements that influence wheat-microbiome interactions, this research has the potential to improve crop resilience, reduce input costs, and contribute to a more sustainable food system. As the project progresses, its findings may pave the way for similar advancements in other crops, helping to alleviate agricultural challenges worldwide.

In an era of increasing environmental stress and resource constraints, the Wheat Alliance project exemplifies how scientific innovation can contribute to a resilient and sustainable agricultural future.
