“Harnessing Culture Collections for Improved Plant Health” workshop – ICPP 2023

December 20, 2022
August 20, 2023


Lyon, France

Satellite Event of

12th International Congress of Plant Pathology (ICCP2023)

Organized in Collaboration with

International Alliance for Phytobiomes Research


8:30am – 12:00pm


This workshop will identify the diversity of culture collections and explore how these living microbial stock collections are being used to improve plant health.

We will present successful strategies and tools that are being used with these essential biological resources to further plant health research. We will discuss proper maintenance and curation of collections, how these essential stocks support plant growth within changing environments, disease diagnostics; and combat biotic and abiotic stresses.

The fundamental knowledge gained with this session will support and enhance efforts that are underway to broaden and strengthen the U.S. and European collection community and their networks.

12:00 – Wrap-up & Adjourn


This was the first in-person USCCN workshop since the 2020 COVID pandemic. USCCN Steering Committee members Neha Potnis and Rick Bennett, and Program Manager Dusti Gallagher hosted and participated in the workshop.

Approximately 20 researchers and industry members attended the event. Presentations covered USCCN, its role and priorities; how the scientific community can engage the vast and diverse collections of bacteria, fungi, and oomycetes in the public and private sector to control plant pathogens, identify biocontrol agents, and enhance plant health research. A private industry perspective, its success stories and future needs was also presented. The workshop culminated with an open panel discussion between the speakers and attendees to consider the needs of the research and culture collections communities and how they can work together to accomplish plant health goals.
