Abstract
Phoma stem canker, caused by the fungal pathogen Leptosphaeria maculans, is a damaging disease on oilseed rape in the UK, causing annual yield losses > £100M despite use of fungicides costing £20M. With recent loss of the most effective fungicides (e.g. Punch C) through EU legislation and predicted global warming, potential yield losses will increase. Use of host resistance to control this disease is becoming ever more important. However, new sources of resistance are often rendered ineffective due to pathogen population changes.
The aims of this project are to monitor the emergence of new virulent races of L. maculans and to develop new control strategies to increase durability of host resistance.
To maintain effectiveness of cultivar resistance against L. maculans, this project will use molecular technology to investigate the differences between different regions in distribution of virulent races of L. maculans in populations assessed from spore samples and from crop plant samples. Results will be used to guide deployment of cultivars with suitable resistance for the region where the corresponding avirulent pathogen races are predominant.
Resistance against L. maculans relies on major resistance (R) gene-mediated qualitative resistance and minor gene-mediated quantitative resistance. The fungus L. maculans has high evolutionary potential to overcome host resistance. Resistance can be rendered ineffective in 2-3 years due to L. maculans population changes from avirulent to virulent. This project will investigate the molecular events leading to virulent mutations in L. maculans by exploiting new genomic information about L. maculans.
Modelling work shows that the range and severity of phoma stem canker will increase under predicted global warming. To investigate the effects of environmental factors (e.g. temperature) on operation of different R genes for resistance against L. maculans, severity of phoma stem canker on cultivars with different R genes will be assessed in field experiments in different regions (i.e. different environments) and in controlled environment experiments at different temperatures.
Recent work showed that R gene-mediated resistance against L. maculans (an apoplastic pathogen) operates by recognition of pathogen effectors through receptor-like proteins (RLPs). The sequences of R genes stable at increased temperatures and the genome sequences of host Brassica napus and its related species B. rapa and B. oleracea will be used to identify candidate R genes coding for RLPs.
New knowledge obtained from this project will be used to develop strategies to improve control of phoma stem canker by using effective cultivar resistance. Improved control of this disease will benefit growers by reducing yield losses. It will also address the challenge of food security. The environment will also benefit from reduced use of fungicides.

Technical Summary
Phoma stem canker, caused by the fungal pathogen Leptosphaeria maculans, is a damaging disease on oilseed rape in the UK, causing annual yield losses > £100M despite use of fungicides. With recent loss of the most effective fungicides through EU legislation and predicted global warming, potential yield losses will increase. Use of host resistance to control this disease is becoming ever more important. However, new sources of resistance are often rendered ineffective due to pathogen population changes. This project will monitor the emergence of new virulent races of L. maculans and prevent them from spreading into new regions; investigate molecular mechanisms of mutation from avirulent to virulence in L. maculans populations; understand the effects of environmental factors (e.g. temperature) on durability of host resistance. New knowledge will be used to develop new control strategies by optimising deployment of host resistance and targeted fungicide application. This project will bring together a consortium of breeders, distributor, farmer and scientists to ensure effective control of phoma stem canker by directly applying knowledge from research into farming practice.
Planned Impact
The involvement of scientists, breeders, agricultural advisors and a farmer in this project will ensure that outcomes of this research are exploited directly to translate scientific outputs into practical improvements to current disease management strategies.
A major beneficiary of the project will be growers. New knowledge produced from this project will not only enable better control of phoma stem canker to increase yield (by reducing yield losses from the disease) but also help to reduce cost of fungicides (by using effective host resistance and targeted fungicide application to eliminate unnecessary sprays) to improve profitability. Therefore, this project will help growers to achieve more sustainable and profitable control of phoma stem canker in oilseed rape.
Another major beneficiary of the project will be plant breeders. It takes 10-15 years to produce a new cultivar with good resistance. Rapid breakdown of resistance in new cultivars is very costly to breeders. The project will investigate differences between regions in distribution of virulent races of L. maculans to guide deployment of cultivars with suitable resistance for the region where the corresponding pathogen avirulent races are predominant. This will increase the lifespan of cultivars by reducing the risk of breakdown of cultivar resistance. This project will also investigate differences between different resistance genes in response to increased temperature. This new knowledge will help breeders to develop cultivars with resistance that is both durable and temperature-resilient.
Agricultural advisors will also benefit from this project by providing better disease control advice. Using the new information about differences in pathogen populations between regions and differences in effects of environmental factors on resistance, agronomists can make recommendations on use of effective host resistance. Using the new information on timing of pathogen spore release, agronomists can make recommendations on timing of fungicide applications to improve fungicide application efficiency and avoid unnecessary fungicide sprays.
Agrochemical companies will also benefit from this project because targeted fungicide application will avoid extensive use of fungicide which may lead to the development of fungicide-insensitivity. Results from this research will help agrochemical companies to maintain or increase the lifespan of fungicides.
Ultimately the public and environment will benefit from reduced fungicide use through improved guidance on deployment of host resistance and targeted fungicide applications. Furthermore, improved disease control in oilseed rape crops will increase yield, which will contribute to national food security. Improved control of phoma stem canker will not only increase yield to contribute to food security, but also reduce greenhouse gas (GHG) emissions to contribute to climate change mitigation.

Description | Phoma stem canker, caused by the fungal pathogen Leptosphaeria maculans, is a damaging disease on oilseed rape in the UK, causing annual yield losses > £100M despite use of fungicides. With limited available effective fungicides and predicted global warming, potential yield losses will increase. Use of host resistance to control this disease is becoming ever more important. However, new sources of resistance are often rendered ineffective due to pathogen population changes. There is a need to monitor emergence of new pathogen virulent races, investigate molecular mechanisms of mutation to virulence, understand effects of environmental factors on effectiveness of resistance and identify resistance genes that are durable so that new control strategies can be developed to increase durability of host resistance. Key achievements: This project has provided new knowledge to increase durability of host resistance. The main activities and achievements/outcomes of this project are in the following five areas. (1) The emergence of new virulent races of L. maculans was monitored over three winter oilseed rape growing seasons (2015/2016, 2016/2017, 2017/2018). The proportions of races of L. maculans If thevirulent against the major resistance gene Rlm7 (the effective resistance gene currently used in UK oilseed rape cultivars) increased from 3% to 16% from 2015/2016 to 2017/2018. This indicates that the resistance gene Rlm7 is at risk of being overcome by the pathogen. There is a need to continue to monitor the pathogen populations for effective use of host resistance. (2) The molecular mechanisms of mutation to virulence in L. maculans for effector (pathogenicity) genes AvrLm1, AvrLm4, AvrLm6 and AvrLm7 were investigated. Mutation to virulence in AvrLm1 was mainly caused by whole gene deletion, while whole gene deletion was observed in only 6% of isolates carrying the virulent alleles of AvrLm4, whole gene deletion was not observed in isolates carrying the virulent alleles of AvrLm6, both whole gene deletion and point mutations were observed in isolates carrying the virulent alleles of AvrLm7. Additional work has been done to sequence the whole genomes of some of those isolates to understand the molecular events leading to virulence. (3) The effects of environmental factors on effectiveness of resistance of 11 winter oilseed rape cultivars for control of phoma stem canker were investigated at five different sites over three growing seasons. There were differences between sites, growing seasons or cultivars in phoma stem canker severity. In general, disease severity was more severe at Morley than at other sites. Cultivars with Rlm7 had less severe canker than other cultivars. There were differences between Rlm7 cultivars, with some Rlm7 cultivars having greater phoma stem canker severity in the last season (2017/2018) than in the previous two seasons. The cultivar Es-Astrid with quantitative resistance showed as a good level of control of phoma stem canker. Combination of Rlm7 with quantitative resistance is a good strategy to increase the durability of Rlm7-mediated resistance. (4) The most recent developments in pathogen and host genomics were used to search for host receptor genes for disease resistance. A total of ten genes related to resistance against L. maculans were found on chromosome A07 of the host Brassica napus. There is a need for further investigation of these genes to develop markers for marker-assisted breeding. (5) Targeted control strategies were developed and delivered to farmers during the course of this project. In each season, information on the timing. Ascospore release at four sites for guiding targeted fungicide applications was provided to consortium members and growers through Hutchinsons' agronomists. The information on pathogen races was provided to consortium members for improving breeding strategies and to guide deployment of cultivars with different resistance in different regions. |

Description | A range of exploitation & dissemination activities have been done.The business case and commercial interest in the project outputs remains strong. Knowledge produced from this project has been passed onto agronomists (especially by Hutchinsons, who estimate that they have reached 13000 farmers per annum through their network of agronomists) and farmers for effective control of phoma stem canker, especially using the information about the timing of pathogen spore release to guide the timing of fungicide spray. We recommend that the industry continues to monitor the emergence of virulent races of L. maculans, which is vital for effective use of major resistance genes for control phoma stem canker. The data on ascospore release in different cropping seasons and in different regions will be used to construct models for predicting timing of ascospore release for optimising fungicide applications. There is a need to investigate mechanisms of host resistance and develop markers for resistance breeding. One of the breeders involved in this project estimated that UH research has benefitted his company by £70000 per year. Given that there were five breeders involved in the project, there is an estimated benefit of £350000 per year. Furthermore, during the course of this project, we observed that some of the Rlm7 cultivars were susceptible to the fungal pathogen Pyrenopeziza brassicae (causing light leaf spot on leaves, stems and pods of oilseed rape). Light leaf spot has recently become an important disease on oilseed rape in England. Previously, light leaf spot was a disease problem on oilseed rape in Scotland; it has now moved to England. We would like to investigate the interactions between these two pathogens on oilseed rape and to investigate host resistance for effective control of both of them. To do further research, we need different partners, such as breeders, farmers and distributors. The main barriers are funding resources and available time of business partners. We recommend that AHDB Cereals & Oilseeds join a future consortium to develop a scheme for deployment of different R genes and quantitative resistance in different regions according to pathogen population races for sustainable management of phoma stem canker. Similar schemes have already been developed in France, Canada and Australia. Standardization of nomenclature of host R genes and corresponding pathogen effector genes has been discussed at the Brassica Genetics Workshop in France (July 2018) and at the International Congress of Plant Pathology conference in Boston (August 2018). Collaborations between France, UK, Australia and Canada in effective use of host resistance for control of phoma stem canker have been discussed. Future funding for continuing the work on control of phoma stem canker in the UK will increase the profile and impact of UK agricultural research. |

Impact | It has been estimated that University of Hertfordshire research on oilseed rape has benefitted UK agriculture by £10-20M per annum. Benefits include understanding to improve resistance of oilseed rape crop cultivars against pathogens that cause diseases that cause losses of more than £150M per annum. This information can be exploited by crop breeders and ultimately by agricultural distributors and farmers. Improved understanding of disease epidemics can be used to improve forecasting of the risk of severe epidemics to guide decisions on fungicide timing. The University has also provided five post-doctoral researchers who have entered the agricultural /horticultural industry (Limagrain, Elsoms, LS Plant Breeding, RSK ADAS, Royal Horticultural Society) on completion of their doctorates. |

Impact | In response to our work, in November 2009 the Chinese government issued a quarantine measure restricting import of oilseed rape seed to ports in regions without the crop, unless seed was certified free from the pathogen Leptosphaeria maculans. This pathogen causes phoma stem canker, a serious disease of oilseed rape. The Chinese decision to protect its crops from this invasive species affected trade with Canada and Australia, and thus to intergovernmental discussions. Our recommendations to prevent entry of the pathogen that have been implemented by China include testing imported seed, surveying crops and training farmers to recognise disease symptoms.Subsequently, recommendations about the risks of crop debris (dockage) in seed cargoes has resulted in discussions between China and Canada, resulting in a high level agreement witnessed by the two prime ministers. |

Collaborator Contribution | Oilseed rape (OSR, Brassica napus L.) is a major crop grown worldwide for production of edible and industrial oil, biodiesel and protein containing animal feed. Diseases are a major factor limiting production, a threat increasing due to climate change and the imminent withdrawal of agrochemicals in Europe. Improved disease control is an urgent priority and for this breeders are increasingly using quantitative disease resistance (QDR) which is considered broad-spectrum and durable. the consortium is identifying and characterising QDR to the most important pathogens of OSR: Sclerotinia sclerotiorum, Verticillium spp, Leptosphaeria maculans, Alternaria brassicicola, Pyrenopeziza brassicae, and the model pathogens Pseudomonas syringae and Botrytis cinerea. We are using a panel of 192 diverse OSR cultivars to screen for resistance against these pathogens in controlled environments and at field trial sites provided by our industrial partner, KWS. We are also quantifying induced defence responses to conserved pathogen-associated molecular patterns (PAMPs) and measuring salicylic acid, lignin, phenylpropanoid, glucosinolate and indole metabolites that are implicated in QDR mechanisms. By combining this data with transcribed sequence information, we are identifying candidate genes involved with defence responses and QDR to the OSR pathogens. We are also studying specific transporter genes GTR1 and GTR2 that control the allocation of glucosinolates to seeds and may impact on QDR. |

Collaborator Contribution | Oilseed rape (OSR, Brassica napus L.) is a major crop grown worldwide for production of edible and industrial oil, biodiesel and protein containing animal feed. Diseases are a major factor limiting production, a threat increasing due to climate change and the imminent withdrawal of agrochemicals in Europe. Improved disease control is an urgent priority and for this breeders are increasingly using quantitative disease resistance (QDR) which is considered broad-spectrum and durable. the consortium is identifying and characterising QDR to the most important pathogens of OSR: Sclerotinia sclerotiorum, Verticillium spp, Leptosphaeria maculans, Alternaria brassicicola, Pyrenopeziza brassicae, and the model pathogens Pseudomonas syringae and Botrytis cinerea. We are using a panel of 192 diverse OSR cultivars to screen for resistance against these pathogens in controlled environments and at field trial sites provided by our industrial partner, KWS. We are also quantifying induced defence responses to conserved pathogen-associated molecular patterns (PAMPs) and measuring salicylic acid, lignin, phenylpropanoid, glucosinolate and indole metabolites that are implicated in QDR mechanisms. By combining this data with transcribed sequence information, we are identifying candidate genes involved with defence responses and QDR to the OSR pathogens. We are also studying specific transporter genes GTR1 and GTR2 that control the allocation of glucosinolates to seeds and may impact on QDR. |

Description | INVESTIGATING MYCOVIRUS-MEDIATED SYSTEMIC RESISTANCE IN OILSEED RAPE |
Organisation | University of Hertfordshire |
Country | United Kingdom |
Sector | Academic/University |
PI Contribution | Oilseed rape, Brassica napus is attacked by many fungal diseases globally, especially light leaf spot (caused by Pyrenopeziza brassicae) and phoma stem canker (caused by Leptosphaeria maculans and L. biglobosa). Previously a quadrivirus (LbQV-1) was characterised that infects L. biglobosa, which then interferes with L. maculans pathogenicity. We are screening and characterising viruses in three fungal pathogens L. maculans, L. biglobosa and P. brassicae and quantifying how the host (oilseed rape) recognises and responds to each fungus. Virus-infected and virus-free isogenic lines of the Chinese L. biglobosa isolate (W10) have been revived to do challenge assays in planta. Endemic isogenic lines have also been produced. RT-PCR conditions were optimised, and LbQV-1 specific primers used to confirm virus presence by dsRNA isolation. To gain insight into the molecular mechanisms underpinning the observed phenotypes, samples were collected from different parts of challenge inoculated plants (i.e. stem, leaf, root, petiole etc.) and compared in terms of gene regulation using next-generation sequencing and quantitative PCR. Field isolates across Europe were collected and, to date, 48 L. maculans, 63 P. brassicae and 19 L. biglobosa isolates have been screened. Seven L. biglobosa isolates have been confirmed to contain LbQV-1, and one isolate from Canada with novel bands of viral dsRNA. Nine samples of British L. maculans have tested positive to the first incidence of a very large dsRNA strand, yet to be sequenced. None of the P. brassicae isolates from six countries across northern Europe appeared to be virus infected. |

PI Contribution | Phoma stem canker is a major disease of oilseed rape in the UK, causing yield losses > £100M p.a. The disease is caused by two related pathogens that attack in different ways: Leptosphaeria maculans (Lm) and L. biglobosa (Lb). Current control focuses only on Lm. Recent work showed that Lb can cause substantial yield losses and is less sensitive to some triazole fungicides than Lm. The pathogen Lb is a growing threat to UK oilseed rape production since no existing methods control it. This project will investigate stem canker epidemics caused by Lb and develop new tools/strategies to control them. To achieve this, we will (1) survey severity of phoma stem canker epidemics caused by Lb; (2) exploit new oilseed rape genomic data to identify genes for resistance against Lb; (3) determine efficacy of new non-triazole fungicides for control of both Lb and Lm; and (4) use Lb genomic information to investigate mechanisms of fungicide insensitivity in Lb; (5) develop new integrated control strategies. |

PI Contribution | The UH team used methods developed in the ERA_CAPs project for reliable screening for resistance which showed wide variation in resistance to the light leaf spot pathogen in a diversity set of Brassica napus cultivars. A total of 195 accessions were tested for resistance against a local population of Pyrenopeziza brassicae. Plants were grown in the glasshouse. Seedlings were spray inoculated with a P. brassicae spore suspension and covered with transparent plastic sheets for incubation at high humidity for 48 hours. The percentage leaf area of sporulation was determined three weeks after inoculation and after another 10 days of incubation at 4C in sealed plastic bags. |
Collaborator Contribution | The John Innes Centre team used associative transcriptomics with the UH phenotype data to identify gene expression markers (GEMs) with expression levels linked to the trait, i.e. quantitative resistance against P. brassicae.

Country | United Kingdom |
Sector | Private |
PI Contribution | Phoma stem canker, caused by the fungal pathogen Leptosphaeria maculans, is a damaging disease on oilseed rape in the UK, causing annual yield losses > £100M despite use of fungicides. With recent loss of the most effective fungicides through EU legislation and predicted global warming, potential yield losses will increase. Use of host resistance to control this disease is becoming ever more important. However, new sources of resistance are often rendered ineffective due to pathogen population changes. This project will develop new control strategies to increase durability of host resistance. To achieve this, we will (1) monitor emergence of new virulent races of L. maculans; (2) investigate molecular mechanisms of mutation to virulence in L. maculans; (3) understand effects of environmental factors (e.g. temperature) on durability of resistance; (4) identify resistance genes that are durable by exploiting the most recent developments in pathogen and host genomics; (5) develop new targeted control strategies and deliver them to farmers. Effective control of this disease will save farmers £27M p.a., besides benefits to breeders, distributors and the environment. |

PI Contribution | The research team at the University of Hertfordshire is leading this research programme. the practical work is led by a PhD student, appointed for 4 years from Jan 2020, with supervision provided by members of staff in the Crop Protection and Climate Change group. All the laboratory work and experimental work in controlled plant growth facilities is done at the University of Hertfordshire, either on the College Lane or Bayfordbury campuses. |
Collaborator Contribution | The student spent the first year of this 4-year PhD project working with RSK ADAS. Most of this work was done from home due to pandemic restrictions. Subsequently, RSK ADAS have been involved in running field experiments for the students. Both RSK ADAS and Perry Foundation attend regular project meetings and HKEP are also represented at these meetings. |
Impact | This collaboration is resulting in presentations at research conferences, for example the International Congress of Plant Pathology, to be held at Lyon, France in August 2023. Offered presentation: 'Understanding Pyrenopeziza brassicae populations for effective control of light leaf spot in winter oilseed rape' by Sapelli, Karandeni Dewage, Ritchie, Fitt & Huang. Collaboration multidisciplinary, involving plant pathologists and geneticists |

Description | Understanding interactions between Leptosphaeria maculans and L. biglobosa for improving control of phoma stem canker on oilseed rape in the UK |
Organisation | Felix Cobbold Trust |
Country | United Kingdom |
Sector | Charity/Non Profit |
PI Contribution | Phoma stem canker is an economically damaging disease of oilseed rape, caused by two co-existing pathogens Leptosphaeria maculans and L. biglobosa. L. maculans produces a phytotoxin called sirodesmin PL. Our work showed that L. biglobosa has an antagonistic effect on the production of sirodesmin PL if simultaneously co-inoculated. To further investigate the effects of sequential co-inoculation on interactions between the two pathogens in terms of sirodesmin PL production, clarified V8 broths were inoculated with L. maculans first, then L. biglobosa sequentially with 1, 3, 5, 7 days in-between, and vice versa. Controls were L. maculans only, L. biglobosa only and L. maculans & L. biglobosa co-inoculated simultaneously. Secondary metabolites were extracted from culture filtrates at 14 days post inoculation and analysed with HPLC. Mycelia were freeze-dried, weighed, and homogenised for DNA extraction and qPCR. There were no significant differences in mycelial weight between treatments. Both sirodesmin PL and its precursors were not produced if L. biglobosa was inoculated before L. maculans; this was due to L. biglobosa inhibiting the growth of L. maculans, confirmed by qPCR. However, the antagonistic effect of L. biglobosa was lost if it was co-inoculated 5 days after L. maculans. |
