About Pseudomonas syringae conference

The Pseudomonas syringae conference stands as a central scientific forum, facilitating the exchange of cutting-edge advancements across various research domains concerning P. syringae and related pathogens that significantly impact numerous economically important crops. Originating in 1973 in France, this conference has traversed multiple countries over the years. Due to the Covid pandemic the previous edition of the conference which would be held in Iceland, has been cancelled and turned into a virtual seminar. Thus the conference is now back after 9 years, so we expect a huge participation of plant pathologists investigating the multifaceted topic concerning the Pseudomonas complex and related pathogens. After 37 years, the eagerly-awaited 2024 edition of the Pseudomonas syringae conference will return to Portugal, hosted in Porto. Participating in this conference offers an exceptional opportunity to connect with peers, forge scientific networks, and foster collaborative partnerships. Don’t miss the chance to present your abstract and join us in Porto!

Invited Speakers


Cindy Morris

Cindy Morris is a senior scientist and research director at the Plant Pathology research unit of INRAE’s center in Avignon, France where she has worked since 1989. Her research focuses on microbial ecology to elucidate how the adaptation of microorganisms to their habitats affects two seemingly conflicting impacts on the environment: their capacity to i) cause disease, and in particular newly emerging diseases and to ii) play beneficial roles in major environmental phenomena – the water cycle in particular. These perspectives emerged from her study of the ecology and life history of Pseudomonas syringae. This has opened questions addressed by her network of collaborators on the nature of non-agricultural habitats of pathogens and their role in disease outbreaks, and tracking pathways of long distance dissemination via the atmosphere and waterway. Details of her activities are on the website of a project she coordinates about modernizing surveillance for plant health (https://beyond.paca.hub.inrae.fr/) and on her blog about the interaction of microorganisms with atmospheric processes (https://bioice.wordpress.com/). This work has led her to be involved in fostering understanding and better integration of plant health management into One Health initiatives.



David S. Guttman is a Professor in the University of Toronto Department of Cell & Systems Biology and Director of the Centre for the Analysis of Genome Evolution & Function. His research focuses on deciphering how bacteria adapt to and manipulate their hosts, emphasizing the evolution of bacterial host specificity and virulence and the dual role of secreted pathogen effectors as both virulence factors and immune elicitors. His group is particularly fascinated by the scope and impact of natural genetic diversity on these host-microbe interactions. The Guttman lab uses a multidisciplinary approach that harnesses comparative and evolutionary genomics, molecular biology, microbiology, plant biology, pathology, bioinformatics, and statistical genetics to gain insight into how pathogen evolution influences the outcome of host-pathogen interactions.


carmen beuzon

Carmen R. Beuzón has a BSc and obtained her PhD in Biological Sciences in 1996 on the regulation of transposition in Salmonella, under the supervision of Prof. Josep Casadesús, at the Department of Genetics, University of Seville. She joined Prof. David Holden’s group at Imperial College London, in 1998 as a Research Associate (EMBO fellow  and MRC funded), working on the molecular mechanisms of pathogenesis in Salmonella up until 2002. Subsequently joined the University of Malaga as Associate Professor (2002-2003), Ramón y Cajal Fellow (2003-2007), Associate Professor (2007-2010), became a member of the joint institute University of Málaga-Consejo Superior de investigaciones Científicas, Instituto de Hortofruticultura Subtropical y Mediterranea (IHSM “La Mayora”), and since 2017 is Full Professor. Since joining the University of Málaga, when she initiated her independent research line as a PI, her research has mostly focused on the identification and molecular and cellular characterization of defense and defense evasion mechanisms involved in the interaction between the model pathogenic bacterium Pseudomonas syringae and the plant, covering from genetic regulation, phenotypic heterogeneity and effector characterization of the pathogen side, to effector targets, immune pathways and regulation on the plant side.

Michelle Hulin

 Michelle did her PhD and first postdoc position at the National Institute of Agricultural Botany (NIAB)/University of Reading in the UK (2013-2020). Here her research focused on the convergent evolution of Pseudomonas syringae pathogenicity on the stone-fruit tree species cherry. She then did a second postdoc at The Sainsbury Laboratory in Norwich, UK (2020-2023) where she worked on P. syringae type 3 effector proteins that can hydrolyse small molecules to promote disease. Michelle joined the Department of Plant, Soil and Microbial Sciences at Michigan State University in the USA in January 2024 as an Assistant Professor. Her research program focuses on factors that drive the evolution of virulence in P. syringae populations with a focus on mobile genetic elements and effector biology.

Tory Hendry

Tory Hendry

Tory Hendry is an evolutionary biologist and microbiologist who studies how host interactions shape the evolution and ecology of bacteria. Tory earned a B.A. in Biology from Williams College and a Ph.D. in Ecology and Evolutionary Biology from the University of Michigan. She held postdoctoral appointments at the University of Arizona and as a USDA NIFA Fellow at the University of California, Berkeley before joining the faculty at Cornell University. The Hendry lab studies host-microbe interactions at the intersection of evolution, ecology and microbiology. We combine genomics and ecological experiments to study interactions of plants, insects and bacteria. Work in the lab aims to integrate data from genomes and experiments to determine how complex host interactions shape bacterial evolution and ecology, and how these interactions feedback to impact hosts.


Emilia Lopez Solanilla

She received the BS degree in Biological Sciences (1994), from Complutense University, Madrid and PhD in Biological Sciences (1998) from Polytechnic University of Madrid, Spain. Full Professor of Biochemistry and Molecular Biology at the Polytechnic University of Madrid. She is head of the research team “Phytopathogenic Bacteria”, at the Centre for Plant Biotechnology and Genomics since 2008. She has been member of the Spanish National Research Agency (AEI) since 2018 at the Agricultural and Forestry research area, being responsible of the area coordination from 2020 to 2022. During the first phase of her scientific carrier, her contribution was focused on the study of resistance mechanisms to plant defense in phytopathogenic bacteria. During a postdoctoral stage (2001-2002) at Cornell University (Alan Collmer´s lab. Department of Plant Pathology, Ithaca, NY, USA), she was part of the initiative responsible for carrying out pioneering studies on bacterial functional genomics in P.syringae. Since then, she has contributed to the study of the early stages of infection in phytopathogenic bacteria and to functional studies related to pathogenesis in different pathosystems. Her scientific interests currently focus on the study of the mechanisms of perception and response to plant and environmental factors in bacterial phytopathogens.
