Phyllosphere 2022

Virtual participation in Session 5: Challenges of Scale in Understanding the Ecology and Management of Phyllosphere Microbial Communities.

As the organizer and sponsor of Session 5 of the Phyllosphere 2022 conference (see the program here), the NSF-funded Agricultural Microbiomes Research Coordination Network has offered to open up this Session 5 (and this session only) for virtual (Zoom) participation. Participation is free but REGISTRATION IS REQUIRED. Click here to register. If you are already registered for the Phyllosphere 2022 meeting, there is no need to register for this virtual session because you will be attending the session in person.

Session 5 will take place on Tuesday July 19th, from 8-10 AM (Pacific Daylight Time) and includes 4 outstanding early-career presenters, plus a short small-group discussion session to explore how SCALE challenges our abilities to understand and manage phyllosphere microbiomes. During the discussion, each breakout group will identify specific challenges and proposed data or methodological approaches to address them.  Small groups will report their findings in a large-group wrap-up, and large-group summaries will be posted on the Phyllosphere 2022 website. Participation by virtual participants in the discussions will be moderated by on-site participants.

Questions?  Contact the Session 5 organizers Linda Kinkel ( or JP Dundore-Arias (

The Scientific and Organizing Committees are excited to welcome you to the University of California – Davis campus from July 17-21, 2022, to attend  Phyllosphere 2022: 11th International Symposium on Leaf Surface Microbiology.

Online registration has been closed. Onsite registration will start July 17th. Click here for pricing.

Check out the program here. We have an AWESOME LINEUP OF SPEAKERS, from various places in the world, covering a wide range of phyllosphere-related topics. You don’t want to miss this!

We are excited to partner with the American Phytopathological Society (APS) on a Focus Issue in the Phytobiomes Journal which will be dedicated entirely to phyllosphere-related research. Registered participants of the Phyllosphere 2022 symposium will receive a $150 discount on the standard publication fees for accepted papers in this issue. See this website for more information.

Many thanks to all sponsors and benefactors for their generous support of this conference! For a full list of sponsors, click here.

Why Phyllosphere 2022?

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.

The theme of the Phyllosphere 2022 symposium is ‘Understanding the rules of phyllospheric life’, with central questions such as these: What unique challenges and opportunities does the leaf surface present to leaf-dwelling organisms? What adaptive strategies are most successful in the phyllosphere? To what extent do these strategies benefit or disadvantage the plant host or the organisms (including humans) that depend on the health of those plants? How might answers to these questions help us grow healthier and more productive plants and trees in the face of a growing human population and uncertainties of climate change?

“I am quite sure that the 9th International Symposium of the Microbial Ecology of Aerial Plant Surfaces (2010) was the most magical meeting of my career!
I was a freshly graduated PhD (new post doc) – and this meeting was my first opportunity to meet all the “superstars” who had steered me through my PhD with their elegant phyllosphere literature!
I was like a screaming fan at an Elvis concert (on the inside) – on the outside – I was  probably trying to appear very academic and serious! Meeting my rockstars; Drs. Brandl, Lindow, Beattie, Morris, Lambais, Vorholdt, Mahaffee, Suslow, Knief, Leveau… in the Oregon countryside was one of the most momentous and special moments of my academic career.
Thanks Phyllosphere – Phytobiome Superstars! Keep on Keepin on!”

“I attended my first International Phyllosphere Symposium in 2015 at the half-way mark of my PhD in microbial ecology. It was the most wonderful meeting I ever attended in terms of quality of the presentations, welcoming atmosphere, and scientific interactions with established researchers. It had long-lasting positive consequences on my career. I am delighted to be going back this year in Davis!”

Mitja Remus-Emsermann
University of Canterbury, New Zealand

“In 2007, I started my PhD in Phyllosphere microbial ecology. 12 years later I do not regret this decision one bit. Our community is warm, welcoming and supportive and our science is cutting edge. Both Phyllosphere symposia I have attended so far were among the best scientific meetings I have been at. I am looking forward join the symposium in the beautiful and laid-back Davis, California.”

Britt Koskella
University of California, Berkeley

“As a relative newcomer into the Phyllosphere field in 2015, I was thrilled to hear about the diverse array of research being done on this important but understudied environment. The community was incredibly welcoming, and the science presented ranged from really exciting fundamental research to novel application within agriculture and beyond. I would highly recommend the meeting to newbies and long-standing phyllosphere researchers alike.”

Nadav Kashtan
The Hebrew University of Jerusalem, Israel

“As a newcomer who recently joined the phyllosphere research community –  I’m truly excited to participate in this one of a kind meeting! See you there.”
