Phyllosphere 12

12th International Symposium on Leaf Surface Microbiology

June 6, 2025 - June 9, 2025

About the Workshop

The ‘phyllosphere meeting’ is a (typically) quinquennial event that brings together experts from around the world with a scientific interest in leaves (and other above-ground parts of plants and trees, including flowers, fruit, buds, petioles, stems, twigs, branches, and trunks) as a habitat for microorganisms.

First held in 1970, the meeting serves as an international platform to share and learn about the latest discoveries in phyllosphere microbiology and as an incubator for new ideas and new collaborations in a field that recognizes how the many essential ecosystem services that plant foliage provides are influenced by the microscopic organisms that can be found on and in leaves (i.e. bacteria, fungi, yeasts, protists, viruses, insects).

As a discipline that became established in the 1950s, phyllosphere microbiology is now recognized as having contributed in significant ways to the study of host-microbe and microbe-microbe interactions using the leaf as an experimentally and conceptually useful model microbiome.

Phyllosphere meetings are truly multi- and inter-disciplinary. With backgrounds in such wide-ranging areas as plant pathology, food safety, microbial ecology, phytochemistry, and vegetation science, participants discuss phyllosphere microbiology in terms of problems such as foliar diseases and contamination of leafy greens with enteropathogenic bacteria, and in terms of solutions such as microbes, proteins and chemicals with plant-growth promoting activities or other commercially viable applications, and bioremediation of atmospheric pollutants.

Code of Conduct

We are committed to making our workshops (workshop(s) organized by OIST, hereinafter “our workshop(s)”) an inclusive space for sharing ideas and knowledge. We will not tolerate disrespectful communication, discrimination, harassment, or bullying in any form. As such, all participants attending our workshops are required to comply with this Code of Conduct. To provide all participants the opportunity to benefit from our workshops, we at OIST are dedicated to a positive, safe and harassment-free experience. Harassment in any form is specifically prohibited.

Harassment involves continued antisocial or unreasonable actions that violate a reasonable person’s personal rights and/or dignity and cause mental suffering, and thus worsen the person’s environment or make him/her anxious about participation. Behavior that is acceptable to one person may not be acceptable to another, so we ask that you use discretion to be sure that respect is communicated. Harassment intended in a joking manner nevertheless constitutes unacceptable behavior. Speech that is not welcomed or that is personally offensive, whether it is based on gender, age, sexual orientation, mental or physical disability, ethnicity, national origin, religion etc. will not be tolerated.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please bring this to the immediate attention of the organizers. If you wish to report an issue concerning the organizers, you can contact the Conference and Workshop Section directly and submit a confidential report by sending an email to workshop-codeofconduct@oist.jp or submitting a report through the ⁠webform.

All complaints will be taken seriously and responded to by the Dean of Research promptly. Confidentiality will be maintained to the extent that it does not compromise the rights of others. Individuals found in breach of this Code of Conduct will be dismissed from the workshop immediately. Retaliation for reporting harassment is also a violation of Code of Conduct, as is reporting an incident in bad faith.
