7.03.11 - Resistance to insects and pathogens


SAVE THE DATE - 8th International Workshop on Resistance Mechanisms and Breeding in Forest Trees

Save the date for the 8th IUFRO International Workshop on Resistance Mechanisms and Breeding in Forest Trees (previously known as the International Workshop on the Genetics of Tree-Parasite Interactions in Forestry), which will take place on June 2 to 6, 2025, in Vernon, British Columbia.
The workshop is sponsored by the IUFRO working parties 7.03.11 “Tree Resistance to Insects and Pathogens” and 2.02.15 “Breeding and Genetic Resources of Five-Needle Pines".
SCOPE OF THE WORKSHOP: The Tree Resistance Workshops series provides an international forum to discuss the status and future plans for both tree resistance breeding programs and scientific research efforts in the field of tree resistance mechanisms against pathogens and insects. The topics of discussion will include, among others, conventional tree breeding initiatives, ecology and genetics of resistance and tree-antagonistic relationships in natural and managed tree populations, mechanisms of recognition and signaling of biotic damage and plant defensive strategies, comparative genomics, GWAS, genomic selection and other genomic initiatives looking for resistance, interactive effects of climate change and abiotic stressors with biotic resistance, the role of microbiome in resistance, and new methods, technology, and tools for resistance screening. The primary audience is those involved with operational breeding programs as well as academic researchers and extension professionals. We welcome the participation of students and early career professionals.

7th IUFRO International Workshop on the Genetics of Tree-Parasite Interactions in Forestry Understanding forest tree-antagonistic interactions in a changing world

Pontevedra, Galicia, Spain; NEW DATE: 12-17 September 2022!.
Units involved: 7.03.11, 2.02.15, 2.02.20, 7.02.05, 7.02.09, IUFRO Task Force on Forests and Biological Invasions.

Managed and natural forests provide essential ecosystem services worldwide. Due to the free of movement ofpeople and goods across biogeographical zones,tree species are increasingly challenged by emergent invasive biotic threats.We can see large range expansions of pests and diseases, as well assudden shiftsto naïve hostspecies. Moreover, climate change is also increasingabiotic tree stresses, whichsynergistically interact with tree resistanceleading to negative effects on tree survival and forest resilience. Althoughforest tree species are known to harbour high levels ofgenetic variation, most remain fairly unstudied, particularly in traits related tohost tolerance and resistancetobiotic and abiotic stressors.To understand such variations, within the framework of the genetics of tree-antagonist interactions, is necessary to forecast the survival and prevalence of forest populations in a changing environment. This knowledge can also be exploited in breeding programs aiming to improve forest health. The scientific community ispushingfor an urgent multidisciplinary and coordinatedeffort to solvethese challenges,making use of current and newknowledge, strategies and technologies. Geneticists, evolutionary biologists, ecologists, phytopathologists, entomologists, plant physiologists, breeders and managers are all involved in this challenge. This workshop will provide the idealforum for updating knowledge, evidences, solutions and failuresbetween scientific, academicand practicalapproaches. It is also an opportunity toenhancethe dialogueof long experienced expertise with the newgenerations of scientists, which will provide creative and newsolutions in the near future.




Abstract submission is now open for the XXV IUFRO World Congress, which will take place in Curitiba, Brazil from Sept 29th to Oct 5th 2019.

Deadline for submission is December 31st 2018, and link for submission is 


Our Working Party has suggested a session:

D2f - Integrating tree resistance development with deeper understanding of local and long-distance movement of pest populations to improve management of invasive pests

Forests around the world are increasingly threatened by global change including invasions by highly damaging and/or lethal exotic pathogens and insect pests (collectively referred to as pests). In this session we discuss how integration of tree resistance development and effective quarantine systems can improve management of invasive forest pests, exploring modern advancements in biotechnology and incorporating a deeper understanding of local and long distance pest movement. Finally, we analyze the common patterns that emerge across invasions of natural and plantation forest systems, as revealed by ongoing advances in pest and host population genetic and genomic studies.


Please consider submitting a contribution



The 6th International Workshop on the Genetics of Tree-Parasite Interactions: Tree Resistance to Insects and Diseases: Putting Promise into Practice is soliciting abstracts for oral and poster presentations.

Deadline for submission is January 21, 2018.

SAVE THE DATE: Tree Resistance to Insects and Diseases: Putting Promise into Practice

August 5-10, 2018, Mt. Sterling, Ohio USA

Make plans to attend the 6th International Conference on the Genetics of Tree-Parasite Interactions: Tree Resistance to Insects and Diseases: Putting Promise into Practice.

The conference will be held at the Deer Creek State Park Lodge and Conference Center, Mt. Sterling, OH, and will feature keynotes by invited speakers, technical sessions with contributed research talks and discussions, and a field trip tour of the USDA Forest Service Northern Research Station Forest Science Laboratory.

This conference will enhance the dialog of experts and young scientists on: 1) the current and emerging challenges posed by pests and pathogens to forest tree species; 2) the current status and extent of our knowledge of genetic foundations of resistance to these threats; 3) the emerging ideas and technologies from around the globe that are relevant to resistance genetics and breeding programs; 4) the successes to date in applied resistance breeding programs; and 5) creating a vision for the next decade for work in this area.

Unlike most scientific conferences, this meeting features a workshop-style format to encourage participation, communication, and engagement. Organizers will bring together a diverse group of scientists from around the world to share current research and build future collaborations related to tree resistance to insects and diseases. Currently, the conference is being sponsored by the USDA Forest Service, several IUFRO units, and the Forest Health Research and Education Center.
