The 4th European conference on Xylella fastidiosa is organised by EFSA with the active contribution of the major EU and transnational research initiatives tackling X. fastidiosa –  BeXyl, BIOVEXO, ERC MultiX and EUPHRESCO. The conference is chaired by Blanca B. Landa, who is coordinating the EU funded project BeXyl (Beyond Xylella), and Giuseppe Stancanelli, who is leading the Plant Health Risk Assessment team at EFSA. The Scientific Committee includes scientists from all the partner organisations and external reviewers. 

The presentations and discussions will take stock of the results from research that has taken place since X. fastidiosa was first detected in Europe in 2013. During this last decade, two major research projects [1] funded by the European Union have filled knowledge gaps on the distinctive elements of the outbreaks, consolidated a resilient network for monitoring and testing, and achieved results that have supported and influenced the activities of researchers, stakeholders and policy makers. The programme of the 4th European conference will reflect the progresses of the multidisciplinary research conducted and will discuss the scientific approaches to develop and test practical and applicable solutions for control and sustainable management of Xylella fastidiosa outbreaks in the EU.

The conference sessions and discussions will cover the latest findings, data and knowledge on X. fastidiosa, including: 

• Pathogen biology, ecology and genetics;
• Epidemiology and modelling of X. fastidiosa diseases;
• Host plant-interactions and resistant/tolerant plant germplasm;
• Surveillance and early detection tools;
• Vectors biology and sustainable control strategies;
• Endophytic microbial resources for X. fastidiosa control;
• Sustainable and integrated pest and disease management strategies for prevention and reduction of the impact of X. fastidiosa diseases.

The European Union Reference Laboratory (EURL) for pests of plants on bacteria was established in 2019. This is an European Union initiative that aims to achieve an overall high level of diagnostics in bacteriology at National Reference Laboratories, primarily across the Member States. The main EURL activities encompass the organisation of proficiency tests (PT) in order to assess the diagnostic competence of the laboratories. Additionally, test performance studies (TPS) and studies to evaluate the suitability of critical reagents in diagnostic tests are annually included. The focus of the EURL activities is on bacteria belonging to the EU priority pests or listed as EU quarantine pests, including Xylella fastidiosa, Ralstonia solanacearum species complex, Xanthomonas citri pv. citri and ‘Candidatus Liberibacter’ on Citrus, Curtobacterium flaccumbaciens pv flaccumfaciens, Pantoae stewartii subsp. stewartii etc.

The 5th EURL Workshop aims to address several current issues and recent developments in the field of plant bacteriology, with the focus on taxonomy and diagnostics. Additionally, during this Workshop the activities and results obtained in TPSs and PTs between September 2022-August 2023 will be presented and the priorities to be given in the Work Program 2024-2025 will be highlighted. Should you have any questions related to the content of the 5th Annual EURL Workshop for Pests of Plants on Bacteria or administrative/practical issues please contact the EURL Bacteriology at EURL-Bacteriology@nvwa.nl.

Scope

Induced immunity and resistance in plants against pathogens and their vectors using beneficial microbes (fungi, bacteria, viruses), natural substances (bacterial metabolites or extracts, plant metabolites or extracts, bio-sourced compounds, etc.), physical stimulation, and allelochemicals, is an ecofriendly biological control strategy that promotes plant health and fits with the current needs for sustainable agriculture. The proposed symposium will focus on the recent advances in agroecological immunity and will target all scientists and actors working or interested by such a concept. Particular attention will be addressed to the recent discoveries regarding cross-protection phenomenon against pathogenic microorganisms threatening plant health and crop production and to the mechanisms underlying plant defense elicitation and priming. The intrinsic and the extrinsic factors affecting the efficacy, the expression, and the sustainability of induced immunity in field conditions will also be considered. The symposium will be organized in several specific sessions (orals, posters, and invited keynotes) dedicated to these topics and related issues. It will be an opportunity to the researchers, agronomists, stakeholders, and industrials concerned by plant induced resistance, and more generally by the agroecological transition in agriculture, to share their recent knowledge and future challenges regarding this topic.

The Caulimoviridae is a family of plant-infecting viruses in the order Ortervirales, which in common with retroviruses, incorporates a reverse-transcription step in the replication cycle. Members of the Caulimoviridae are found throughout the world and infect a wide range of monocot and dicot plants, causing economically important diseases such as rice tungro and cacao swollen shoot. Cauliflower mosaic virus, the type species of the Caulimoviridae, has provided an exceptional model system to investigate all manner of biochemical pathways in plants, as well as fundamental aspects of virus replication, virion structure, intercellular movement and vector transmission. Endogenous viral elements (EVEs) that derive from caulimovirids are widespread in the genomes of tracheophyte plants, and some remain replication-competent and can cause spontaneous infections through activation by biotic or abiotic stresses. However, the majority of caulimovirid EVEs are replication-defective and can constitute a very large proportion of the plant genome. How these EVEs may benefit the plant is still a matter of conjecture and is a very active area of research. Caulimovirid EVEs also act as molecular fossils and can be used to infer the evolution of plant viruses over unprecedented timescales. This 1.5 day symposium will offer a unique opportunity to present the latest advances in research on the Caulimoviridae and to discuss future research directions and collaborations. It will be divided into four sessions covering key issues :

Session 1 - Replication and host-vector-virus interactions.
Session 2 - Diagnosis, epidemiology and control.
Session 3 - Endogenous viral elements: pathogenicity, functions and insights into virus evolution.
Session 4 - Summation: highlights of meeting, gaps in knowledge, taxonomic issues.
Sessions 1-3 will start with an opening keynote lecture providing the audience with an overview of the state-of-the-art on each topic, to be followed by selected presentations by participants.

Fusarium wilt of banana (FWB) caused by Tropical Race 4 is a major threat to banana production. The commonest Cavendish banana varieties are very susceptible to this pathogen. The satellite comprises sessions that address the current distribution and impact of FWB, the biology of the causal fungi, novel control methods from quarantine strategies to gene silencing, new approaches in genetics, genomics and breeding, and an update on GM strategies. The final session underscores the importance of global alliances and partnerships. The meeting is followed by a social event and a dinner sponsored by Chiquita. 

This workshop will allow the GPHA community to discuss and decide on further steps for the project. These steps will involve elements of conclusions, recommendations, and perspectives. Perspectives can be according to research, education, and policy. Specifically, the workshop will aim to identify organisation and timeline (1) to produce and disseminate conclusions and recommendations from the GPHA results and (2) for future activities within the GPHA project.

This workshop will identify and explore the diversity of culture collections and how they are being used to improve plant health. Living microbial collections can play a pivotal role in untangling community level interactions and contribute basic knowledge that can be translated in real world solutions. Workshop presentations will discuss proper maintenance and curation, successful strategies and tools to further plant health research and identify critical research areas: increasing plant growth within changing environments, disease diagnostics, reducing biotic and abiotic stresses, and microbiome manipulation. The fundamental knowledge gained with this session will support and enhance efforts that are underway to broaden and strengthen U.S. and European collection communities and their networks.

High-throughput sequencing (HTS) technologies have revolutionised plant virus research and diagnostics by accelerating the discovery of new viruses and by providing a sensitive untargeted approach for the detection of viruses. The latter, together with high data-generation potential of HTS, enables discovery of new and emerging viruses from diverse hosts, archived or ancient samples, and untargeted virus detection in diverse matrices, as well as research on a broad range of topics, such as plant virus epidemiology, diversity and evolution. Many new plant virus discoveries, increased availability of sequence data, and a lagging biological characterisation of HTS-based findings call for a broad consideration on harmonisation of sequencing and data analysis approaches, as well as the interpretation of the results from the scientific and regulatory perspective. During this satellite meeting, different aspects of applying HTS in plant virology will be addressed and discussed. Topics will include: discovery and detection of new and emerging viruses; virus diversity, epidemiology, and evolution studies; development of virus detection and identification protocols and validation of HTS-based tests for plant virus diagnostics.

This satellite meeting aims to foster links between the communities of researchers modelling plant disease and those interested in remote sensing. Indeed, the latter do not tend to have a background in disease modelling while the former are sometimes skilled data scientists but, typically, have limited understanding of the opportunities and challenges involved in interpreting remotely sensed information. Bringing these two communities together will clearly stimulate further developments in both fields. A more concrete focus will be on how remote sensing approaches can contribute to an enduring preoccupation of disease modellers, calculating the basic reproduction number, R0.

Image classification tools that uses Artificial Intelligence is increasingly becoming relevant as a new approach for field detection of plant health issues. This session will cover the basics of image classification approaches by an industry presenter (Statlogic) followed by discussing real-world applications developed or in the process of development. The session will also review some of the new open-source image classification programs. This session is expected to be a hybrid of educational as well as research driven presentations and will shed light on opportunities in utilizing images for developing Artificial Intelligence tools in plant pathology.

Oomycetes are a group of filamentous eukaryotic microorganisms widely present in natural environments, some of them including the main pathogenic species for plants, algae and animals. This international workshop will be devoted to the presentation of the most recent research on these organisms, aiming in particular at developing new control methods to limit their impact on agriculture and natural environments.

The workshop will include sessions devoted to molecular mechanisms of oomycete pathogenicity, host resistance, evolution and population genomics, and innovations in control.

Having healthy plants is key to providing food security for the 9.8 billion people expected by 2050. But crops are facing many challenges, among them climate change and an increased exposure to biotic and abiotic stressors, such as pests, poor soil quality, low water availability and excessive heat. In order to make agriculture more productive and sustainable, we need to study plants in their biological, physical and environmental contexts, i.e. the “Phytobiome”. Phytobiomes research – a new, cross-cutting, multidisciplinary, holistic approach – focuses on the complex interactions between plants, microorganisms, soils, climate, environment, and management practices. In this workshop, we will showcase examples on how phytobiomes science can provide solutions to produce healthy plants to ensure food security for future generations.

Healthy seeds maximize chances for healthy plants and good harvests, particularly for vegetables as any damage leads to reduced yield and fruit marketability. Vegetable seed industry is active through the International Seed Health Initiative (ISHI), driven by the International Seed Federation (ISF) for developing and validating standard protocols for disease detection. Recent molecular techniques development helped hastening tests and increased sensitivity. Result biological relevance needs to be kept in mind as detection of pathogen particles does not necessarily lead to expressed diseases. Overview of ISF, ISHI and main methods will be presented here. A roundtable on topics like biological relevance, seed transmission and sensitivity of detection methods is part of the program.

Powdery mildew fungi (Erysiphaceae) are common obligate biotrophic pathogens of over 10,000 plant species. Some cause economically important diseases of many agricultural and horticultural crops. Currently, there are more than 30 genome assemblies available from over 15 species representing eight powdery mildew genera. The Symposium will focus on the use of these genomic resources and other molecular data to better understand the identification, phylogeny, evolution, and host range expansions of powdery mildew fungi, and their interactions with host plant tissues at molecular level.

Rice is an important staple crop and critical for global food security. Both endemic and emerging pathogens greatly affect rice production and cause huge yield losses. This workshop aims at gathering people involved in research on rice pathogens and on their interactions with their host plant, and on developing control methods of rice diseases. It will provide a unique opportunity to get a worldwide overview of current rice diseases, gain information on emerging diseases, update knowledge in cutting-edge research topics and establish collaborations with a large community.

Root rot diseases can be difficult to manage due to the broad host range and long-lived survival structures of the pathogens. Fungicides, crop genetic resistance, and cultural practices can be effective, but educating producers and implementation of the best practices at broad scales is difficult. In this workshop we will feature basic and applied work on soil health as it is related to plant diseases and how to communicate with stakeholders to implement best practices on the farm. Research presentations will be followed by interactive small group discussions where participants will exchange information to overcome research and outreach barriers.

Transposon-sequencing (Tn-Seq) emerged as a powerful molecular approach to investigate behavior of plant pathogens and symbionts along host colonization processes. This workshop will illustrate different ways to use Tn-Seq and the strengths and limits of the Tn-mutant screening approach in microbes, including bacteria and eucaryotes.

Ralstonia solanacearum is one of the most destructive bacterial plant pathogens worldwide, causing bacterial wilt and major crop losses, especially in the solanaceous plant family. While a solid understanding of the molecular interactions between the pathogen and crop plants have been established, these interactions are poorly understood in more complex rhizosphere microbiomes. Moreover, while increasing evidence suggests that plant-pathogen interactions can evolve rapidly, this is seldom recognised in the context of plant pathogen control.

In this session, we will bring together experts from microbiome research, systems biology, plant pathology, experimental evolution and plant pathogen biocontrol to build a multidisciplinary view of the ecology and evolution of R. solanacearum in rhizosphere microbiomes. We aim to produce a holistic summary of how ecological and evolutionary information could be harnessed for bacterial wilt biocontrol and to identify key environmental drivers associated with disease outbreaks. We also welcome researchers interested in the R. solanacearum pangenome to better understand its genetic diversity in space and time.

The satellite event will be accompanied by a special issue on the topic for example in FEMS Microbiology Ecology edited by Ville Friman (current Editor) and other organizers.

Writing grants can be very challenging for starters to figure out, and it is a competence that many do not have an opportunity to learn while in graduate school. This workshop will be particularly beneficial to early career professionals and graduate students. Areas to be covered will include but not limited to good grantsmanship, international opportunities, logic models, impact statements, effective communication of content and communication of outcomes of winning proposals. At the end of the workshop, participants are expected to be more knowledgeable on: how to find the appropriate grants to apply to, how to use logic model to develop a blueprint for grant proposals, how to tell a good story, components to a successful proposal, efficient budgeting and project evaluation/management tools. This workshop will involve lots of creative activities like using the GOPP to create a proposal concept, writing impact statements, filling in NIFA/NSF, INRAE, and EAFRD budget forms.
