Host-Microbe Interactions

Welcome to our webpage! Our research program uses molecular, genetic, genomic, cell biology, and computational methods to study the interactions between plants and their symbionts. We focus primarily on plant pathogenic bacteria and the molecular dialog that is exchanged with its warring partners. Follow the "research" tab for brief comments on what we study. Links to publications are provided. We are also highly collaborative and our research includes topics such as microbial signaling, mRNA processing, and the study of other types of plant-pathogenic organisms.

Best wishes to Dani Stevens

Dani Stevens graduated (stayed for the summer) and will be starting graduate school in September.

Lemon trees are rejoicing that she'll be focusing on plant pathology rather than plant nutrition or plant physiology (especially xylem function).

Best wishes!


New publication!

A paper by Ed Davis was published today. This describes a very interesting study on the evolution of a species of plant-associated bacteria. The amount of work and time this paper represents is quite remarkable. There is a common misconception that because work is "computational" that it is easy. At best, computational work may be easier to re-run.

Congrats to graduates!

Today, Heidi and Dani will be receiving their degrees. We'll miss you Heidi! Luckily, Dani will stay for the summer. We also wish Kody the best and thank him for all of his hard work.

New publication!

Some individuals were not very pleased with the findings reported in Savory et al (2017). We responded in a two-staged process, with a correction and a response to comments.

Congratulations to Michael Belcher

Michael Belcher, who graduated from OSU in 2017 and is now a graduate student at UC Berkeley, received an NSF GRFP. Congratulations!

Congratulations to Dr. Elizabeth Savory, Skylar Fuller, and Dr. Alex Weisberg

A paper by these three co-first authors was published today in Elife. There are three main take home messages in this paper: 1) A virulence plasmid is sufficient to transition beneficial Rhodococcus to pathogenic Rhodococcus, 2) In a nursery setting, the movement of plasmids and the movement of pathogenic cells explain transmission patterns, and 3) The conclusion that virulence gene-lacking Rhodococcus are the causative agent of a newly described syndrome of pistachio may have been incorrectly diagnosed.
