Delivering Sustainable Wheat: Delivering Resilience to Biotic Stress (Rothamsted Research)

Lead Research Organisation: Rothamsted Research

Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Technical Summary

WP2 aims to improve the resilience of wheat production systems to biotic stresses frequently encountered in high yielding UK-European (and global) wheat regions. This WP will investigate biotic threats which typically cause grain yield losses in the range 10 to 25% even after the correct application of fully integrated control options. The WP will focus on major anticipated/recurrent UK European- global threats including stem rust wheat blast Fusarium Head Blight (FHB)/Scab caused by Fusarium graminearum (Fg) and F. culmorum (Fc) Septoria Leaf Blotch caused by Zymoseptoria tritici (Zt) take-all root disease yellow rust and two aphid species (Rhopalosiphum padi (Rp) and Sitobion avenae (Sa)) that transmit various viruses and exploit comparative analyses. As a result of DFW and other investments we will in this WP deliver molecular targets in wheat and in the major wheat pests and pathogens which can be exploited to sustain future productivity in the short medium and longer terms. Our approach will mirror that used to counter infectious diseases of humans as exemplified by the recent Covid-19 pandemic. These were to: (1) increase host immunity (vaccination) (2) understand the molecular basis of infection and deploy selective antiviral chemistry and (3) monitor (surveillance) of pathogen strains and predict new emergence/ epidemics. WP2 will deliver resilient wheat crop protection via a similar triple-pronged cross institute approach. Specifically we will identify and characterise wheat germplasm and genes which will (1) boost wheats natural immunity to multiple diseases whilst also identifying genes/processes which pathogens may exploit (“susceptibility factors”) as potential weaknesses with emphasis on those exploited by multiple pathogens. We will also (2) functionally identify the genes that are pathogen weaknesses based on their importance for wheat infection. Through large-scale comparative genomics and pangenomics we will refine these lists for “Accessible SMART targets” for future interventions which can be selectively targeted in pathogens/pests as opposed to beneficial/non-target organisms. Finally we will (3) further develop and deploy state of the art surveillance strategies to enable rapid identification and response to new variants of existing threats as well as detect new and emerging threats to UK-global wheat production.

Description Work Package 2 - Delivering Resilience to Biotic Stress
Key Findings
2.1 Exploring and exploiting host resistance and susceptibility
2.2 Understanding and revealing vulnerabilities in pathogen and pest infection biologies
2.3 Accelerating our response to future pathogen and pest threats
DSW has made significant progress towards our understanding of the molecular mechanisms underpinning major diseases of wheat. Using PacBio HiFi sequencing technology we have generated nine near-complete genome assemblies, including two different virulence lineages, for the globally important root infecting take-all disease pathogen Gaeumannomyces tritici (https://doi.org/10.1186/s12864-025-11432-0), identified a novel source of resistance to septoria tritici blotch (Zymoseptoria tritici) (https://doi.org/10.1038/s41477-025-01920-2) and have demonstrated that a resistance gene for powdery mildew (Blumeria graminis) also confers resistance to wheat blast disease (Magnaporthe oryzae) within the Watkins landrace collection of wheat (https://doi.org/10.1038/s41477-024-01718-8). Significant progress was made to further understand the virulence factors and secreted effectors of Fusarium graminearum that causes fusarium head blight of wheat and contaminate the harvested grain with harmful mycotoxins (https://doi.org/10.1111/mpp.13485, 10.1094/MPMI-08-24-0103-FI).
Meeting our objectives for the DSW ISP we are identifying proteins that have potential as intervention targets within fungal pathogens of wheat. We have demonstrated a gene of F. graminearum, FgKnr4, is crucial for oxidative stress tolerance, cell cycle stress tolerance, morphogenesis, cell wall formation in fungal spores and full virulence (https://doi.org/10.1371/journal.ppat.1012769). Promisingly, the Knr4 gene is highly conserved and specific to the fungal kingdom. Disruption of the Knr4 orthologue in Z. tritici led to parallel phenotypes of reduced fungal growth and loss of virulence. These findings suggest that Knr4 could serve as a potential target for controlling fungal diseases in crops.
Through an international collaboration, we have generated an improved gene annotation of the fungal wheat pathogen Zymoseptoria tritici for the global reference isolate IPO323. Based on combined Iso-Seq and RNA-Seq evidence we present a significantly refined and more accurate annotation of the Z. tritici genome by integrating long-read Iso-Seq with short-read RNA-Seq data, resolving inconsistencies in earlier gene predictions and providing a high-confidence set of gene models that will improve functional studies of this major wheat pathogen and support future disease control research (https://doi.org/10.1094/MPMI-07-25-0077-TA).
We reported near-complete genome assemblies for nine Gaeumannomyces strains (including distinct virulence lineages of G. tritici and first genomes for G. hyphopodioides and G. avenae), and found that differences in candidate secreted effector proteins, biosynthetic gene clusters and gene copy-number variation correlate with pathogenic versus non-pathogenic lifestyles and lineage-specific traits, providing foundational genomic resources for studying take-all disease, virulence variation and fungal evolution (https://doi.org/10.1186/s12864-025-11432-0).
Giant "Starship" transposable elements in fungi tend to group according to the taxonomy of their host species when analysed with an alignment-free k-mer phylogenetic approach using the new Gaeumannomyces genomes described above. This suggests that horizontal transfer of these large cargo-carrying elements is less frequent across broad evolutionary distances and that whole-element relationships often reflect host lineage and cargo gene similarity rather than just the tyrosine recombinase "captain" gene (https://doi.org/10.1093/g3journal/jkaf082). These new finding challenged the current global consensus and thinking on Starship functions and movements in fungi, which had previous only been studied by focussing on sequence diversity present in the tyrosine recombinase "captain" gene.
We were part of the first team to report that, in the 2025 growing season, Yr15-mediated resistance which once offered long and broad-spectrum defence and is present in most commercially grown wheat varieties was overcome by virulent yellow rust pathogen isolates across parts of the UK, Europe and globally. Yr15 has been widely deployed in breeding since the late 1990s, highlighting a significant resistance gene breakdown has likely been driven by strong selection pressure from extensive cultivation of Yr15-containing cultivars and underscoring the need for diversified resistance strategies in breeding (https://doi.org/10.1002/ndr2.70067).
Wheat stem rust (Puccinia graminis f. sp. tritici) has re-emerged and expanded in western Europe since 2022, likely driven by airborne spore arrival and cultivation of later-maturing varieties. We found that recently emerged isolates can infect most current UK wheat cultivars and found that existing disease risk models use outdated temperature responses. We argue that updated models and urgent management actions are needed to limit further stem rust impacts on European wheat production (https://doi.org/10.1111/nph.19864).
We continue to be responsive to new disease threats. In the 23-24 season breeding and agronomy partners alerted us to high levels of gout fly (Chlorops pumilionis) damage in the UK. In response we designed an early drilled, replicated field screen of the majority of the Watkins bread wheat collection without insecticide treatment. If gout fly is a problem in the 25-26 season this will enable us to identify resistant accessions and potentially map resistance genes.
Using AirSeq, our sequencing-based method for detection of airborne biological material, we sampled at Breeders Observation Panel and Breeders Toolkit sites across the East of England during 2023 and 2024. These samples have been sequenced and data are currently being analysed, but early work has demonstrated geographical and temporal variance of several key wheat pathogens including those responsible for yellow rust, brown rust, septoria blotch and powdery mildew.

Description • DSW training courses • Women in Wheat - Pathogen- Host Interactions Database Funding was secured from BBSRC to support a 12-month project to expand the success of the Rosalind Franklin Women in Wheat Champions programme, initiated at JIC and TSL, across DSW organisations. The project is a collaboration between JIC, TSL and Rothamsted Research and aims to address the severe lack of female representation in wheat research in academia at the independent career stage. As part of this project in January 2025, thirteen research leaders and senior staff from seven UK research institutes and universities undertook leadership training at JIC specifically tailored for enhancing gender awareness. Over three days the participants received practical training on inclusive leadership. During early spring of 2025 twenty-nine early-career female wheat researchers from twelve different organisations undertook female leadership training at JIC. Delivered as two separate interactive workshops participants explored a broad range of concepts essential to becoming an effective scientific leader. Beyond the in-person sessions, female ECRs were also encouraged to join the established Rosalind Franklin Women in Wheat Champions one-to-one career development mentoring provided by research leaders in DSW, with eight additional women joining in this period. The women can join the annual career development workshop held at JIC/TSL to further prepare them for the next stages of their careers. (https://doi.org/10.5281/zenodo.18456184) Plant breeding, food and nutrition, and maths/statistics are vulnerable skills where training and development is required (BBSRC and MRC review of vulnerable skills and capabilities-2017). We have worked with a range of age groups in these areas including regional engagement activities such as at the Norwich Science Festival and through the Gatsby Plant Science Summer School for undergraduate students. In November 2024 we hosted the first online "DSW in Practice" course to train the next generation of wheat breeders. Over two days, 19 students joined from 9 countries to learn from over 40 DSW members; students gained most from the interactive demonstrations of tools and software developed by DSW. In 2025 our training course was redesigned for undergraduates, to increase awareness and knowledge of food security, plant breeding, wheat research and careers in plants science. Over a hundred students attended the course, representing 19 UK universities. Based on feedback received after attending the course, students were more likely to pursue a career in plant science, had improved knowledge of wheat breeding and its importance and had an increased awareness of the range of plant science careers available. The Pathogen-Host Interactions Database - PHI-base which is partially supported by DSW funding has become involved in supporting an essential new requirement for commercial activities. The EU law has recently changed and all newly registered biological microbes to be registered for used for commercial purposes to control of pests and/or pathogens in arable crops, horticultural crops and farmed tree species have to have their genomes fully sequenced, assembled and fully annotated. Then the predicted gene repertoire in each microbial genome has to be searched specifically for two specific attributes, namely (1) the presence of known toxin genes and (2) the presence of known virulence genes. Globally, PHI-base is the only database where both types of information are freely available and are regularly updated from the peer reviewed literature. We were alerted to these new EU legal requirements in 2025 by a global AgBiotech company and are actively collaborating to understand these new EU legislative mandatory requirements . We therefore envisage that going forward this new use for PHI-base will become more frequently required by the commercial sector.

Title Identification and functional characterisation of a locus for target site integration in Fusarium graminearum 
Description Background: Fusarium Head Blight (FHB) is a destructive floral disease of different cereal crops. The Ascomycete fungus Fusarium graminearum (Fg) is one of the main causal agents of FHB in wheat and barley. The role(s) in virulence of Fg genes include genetic studies that involve the transformation of the fungus with different expression cassettes. We have observed in several studies where Fg genes functions were characterised that integration of expression cassettes occurred randomly. Random insertion of a cassette may disrupt gene expression and/or protein functions and hence the overall conclusion of the study. Target site integration (TSI) is an approach that consists of identifying a chromosomal region where the cassette can be inserted. The identification of a suitable locus for TSI in Fg would avert the potential risks of ectopic integration. Results: Here, we identified a highly conserved intergenic region on chromosome 1 suitable for TSI. We named this intergenic region TSI locus 1. We developed an efficient cloning vector system based on the Golden Gate method to clone different expression cassettes for use in combination with TSI locus 1. We present evidence that integrations in the TSI locus 1 affects neither fungal virulence nor fungal growth under different stress conditions. Integrations at the TSI locus 1 resulted in the expression of different gene fusions. In addition, the activities of Fg native promoters were not altered by integration into the TSI locus 1. We have developed a bespoke bioinformatic pipeline to analyse the existence of ectopic integrations, cassette truncations and tandem insertions of the cassette that may occurred during the transformation process. Finally, we established a protocol to study protein secretion in wheat coleoptiles using confocal microscopy and the TSI locus 1. Conclusion: The TSI locus 1 can be used in Fg and potentially other cereal infecting Fusarium species for diverse studies including promoter activity analysis, protein secretion, protein localisation studies and gene complementation. The bespoke bioinformatic pipeline developed in this work together with PCR amplification of the insert could be an alternative to Southern blotting, the gold standard technique used to identify ectopic integrations, cassette truncations and tandem insertions in fungal transformation.

Title Identification of a locus for target site integration in Fusarium graminearum 
Description We developed a vector system for target site integration (TSI) in an intergenic chromosomic region of the Fg genome. Insertion of the expression cassette in this chromosomic region (TSI locus1) does not alter either fungal growth of fungal virulence. Integrations in the TSI locus1 allow the expression of different genes fusions and activities of virulence specific promoters were not altered by integration into the TSI locus 1. Complementation tests were successfully done on three test genes. Finally, we established a protocol to study protein secretion in wheat coleoptiles using confocal microscopy and the TSI locus1 for stable expression of different gene fusions.

Impact The TSI locus1 can be used for diverse studies including promoter activity analysis, secretion and gene complementation and localisation studies. Therefore, the vector system has already been used in multiple ongoing BBSRC funded research projects in the laboratory. A PhD student and a postdoctoral researcher have successfully used the vector system for gene complementation studies. The vector system will also be used to study protein secretion in a new collaborative project with US researchers. The project aims to identify fungal secreted proteinases that can be used to engineer fungal resistance in wheat. The new vector system is available from ADDGene.

Title A conserved fungal Knr4/Smi1 protein is vital for maintaining cell wall integrity and host plant pathogenesis 
Description Filamentous plant pathogenic fungi pose significant threats to global food security, particularly through diseases like Fusarium Head Blight (FHB) and Septoria Tritici Blotch (STB) which affects cereals. With mounting challenges in fungal control and increasing restrictions on fungicide use due to environmental concerns, there is an urgent need for innovative control strategies. Here, we present a comprehensive analysis of the stage-specific infection process of Fusarium graminearum in wheat spikes by generating a dual weighted gene co-expression network (WGCN). Notably, the network contained a mycotoxin-enriched fungal module that exhibited a significant correlation with a detoxification gene-enriched wheat module. This correlation in gene expression was validated through quantitative PCR. By examining a fungal module with genes highly expressed during early symptomless infection, we identified a gene encoding FgKnr4, a protein containing a Knr4/Smi1 disordered domain. Through comprehensive analysis, we confirmed the pivotal role of FgKnr4 in various biological processes, including morphogenesis, growth, cell wall stress tolerance, and pathogenicity. Further studies confirmed the observed phenotypes are partially due to the involvement of FgKnr4 in regulating the fungal cell wall integrity pathway by modulating the phosphorylation of the MAP-kinase MGV1. Orthologues of FgKnr4 are widespread across the fungal kingdom but are absent in other Eukaryotes, suggesting the protein has potential as a promising intervention target. Encouragingly, the restricted growth and highly reduced virulence phenotypes observed for ?Fgknr4 were replicated upon deletion of the orthologous gene in the wheat fungal pathogen Zymoseptoria tritici. Overall, this study demonstrates the utility of an integrated network-level analytical approach to pinpoint genes of high interest to pathogenesis and disease control.

Title Combined pangenomics and transcriptomics reveals core and redundant virulence processes in a rapidly evolving fungal plant pathogen 
Description Studying genomic variation in rapidly evolving pathogens potentially enables definition of genes supporting their "core biology" present, functional and expressed by all strains or "flexible biology", varying between strains. Genes supporting flexible biology may be considered to be "accessory", whilst the "core" gene set is likely to be important for common features of a pathogen species biology, including virulence on all host genotypes. The wheat-pathogenic fungus Zymoseptoria tritici represents one of the most rapidly evolving threats to global food security and was the focus of this study

Genes supporting flexible biology may be considered to be "accessory", whilst the "core" gene set is likely to be important for common features of a pathogen species biology, including virulence on all host genotypes. The wheat-pathogenic fungus Zymoseptoria tritici represents one of the most rapidly evolving threats to global food security and was the focus of this study.

Impact The EU law has changed and all newly registered biological microbes to be registered for used for commercial purposes to control of pests and/or pathogens in arable crops, horticultural crops and farmed tree species have to have their genomes fully sequenced, assembled and fully annotated. Then the predicted gene repertoire in each microbial genome has to be searched specifically for two specific attributes, namely (1) the presence of known toxin genes and (2) the presence of known virulence genes. Globally, PHI-base is the only database where both types of information are freely available and are regularly updated from the peer reviewed literature. We were alerted to these new EU legal requirements in 2025 by a global AgBiotech company and are actively collaborating to understand these new EU legislative mandatory requirements . We therefore envisage that going forward this new use for PHI-base will become more frequent by the commercial sector.

Results and Impact The Take-all living plot display involved the resistance accession Watkins 777 and the susceptible accession Paragon and was accompanied by one poster explaining the effects of different weather variable at different times of the year on take-all disease severity and incidence and a second poster on use of genetics to improve resistance to Take-all root disease.

The overall aim of this display was to promote ways to increase wheat root health in the future through the deployment on novel genetics. The weather variables poster helped to explain to the very diverse audience the conditions which are most favourable to the development of this serious take-all root disease

Results and Impact DSW in practice was an online event done over two days. All the researcher members in WP2 were involved in devising and giving oral presentation and either leading or taking part in interactive discussions on what are plant diseases of wheat, how the various fungal pathogens are currently controlled and what new approaches could be devised in the future. The graduate students and other researchers based at UK based wheat breeding companies were also taught techniques such as fungal pathogen transformation and the use of in field air samples combined with metagenomics analyses to determine the prevalence of specific pathogenic species. This 3 hour training session was highly interactive.

Results and Impact Take-all is the most important root fungus of wheat (20% yield). It has largely been ignored because of the difficulties associated with working with soil fungi. We have Increased the genomic resources of this system by adding five near complete genomes to the species and another four from related species. We have also identified giant cargo carrying mobile elements and applied a new technique for analysing them which is shedding light on their ability to horizontally gene transfer.
