Boris A. Vinatzer’s research spans from molecular plant-microbe interactions to molecular evolution and taxonomy of plant pathogenic bacteria. He takes advantage of the revolution in DNA sequencing technology to develop bioinformatics tools for precise and fast detection, classification, and identification of plant pathogens and biocontrol agents. A second area of research focuses on environmental microbes that may play a role in the formation of precipitation. Dr. Vinatzer teaches an interdisciplinary undergraduate course in Microbial Forensics and Biosecurity in which he covers concepts of biosecurity through examples of bioterrorism and natural disease epidemics of humans, animals, and plants. Dr. Vinatzer has published over 75 peer-reviewed research articles and book-chapters.

Current projects:

genomeRxiv: a microbial whole-genome database and diagnostic marker design resource for classification, identification, and data sharing

Although invisible to the human eye, microorganisms have an immense impact on society and the environment. They keep soil healthy, cause disease, and give us tools like antibiotics to fight the diseases other microbes cause. Accurate and precise identification of microbes is thus essential for understanding microbiology in general, for diagnosis and treatment of diseases, and for maintaining a healthy society and a healthy environment. The DNA sequencing revolution allows us to read the genetic code of individual microbes, and use this for fast and accurate identification. However, we cannot do this without databases that precisely define classes of microorganisms, and associate them with their unique characteristics. We also need fast computer programs that can handle the large amounts of data involved and, to be most useful to the world, we need to allow anyone, anywhere to upload the genetic data for the microbes they find, and quickly get an accurate identification of their likely impact. Therefore, we are building genomeRxiv, a Website and a database of hundreds of thousands of accurately catalogued and classified public genome sequences of bacteria and archaea. Building on existing work, a combination of fast and accurate algorithms will be employed for users to query the database. A unique feature will keep submitted genomes private, which will enable and stimulate networking and facilitate sharing of genome sequencing results among scientists across academia, industry, and government, leading to a more efficient, and economically stimulating, use of research funds. Automated design of diagnostic tools will facilitate detection and regulation of pathogens for biosafety and biosecurity and directly impact clinical and veterinary medicine, plant pathology, and the use of beneficial microbes in agriculture. The scientific community will be trained in the use of genomeRxiv, and undergraduate and graduate students of diverse backgrounds will receive education at the interface of biology and computer science.

Unraveling mechanism and ecological role of non-proteinaceous ice nucleation activity in a Gram-positive bacterium

Some bacteria have the surprising ability to catalyze the freezing of water. These bacteria may even contribute to the formation of precipitation in clouds. Little is known about how and why bacteria acquired this ability, which in scientific terms is called “ice nucleation activity”. In this project, the Vinatzer lab will study the bacterium Lysinibacillus parviboronicapiens, which was recently isolated from precipitation and which secretes a yet unidentified molecule with ice nucleation activity. The Vinatzer lab plans to identify the genes that are necessary to synthesize this molecule, to study where the bacterium typically lives, and how it benefits from ice nucleation activity. One of the long-term goals is to understand the detailed mechanism this molecule uses to nucleate ice. This knowledge could improve our ability to predict amount and frequency of precipitation or to influence weather by increasing rainfall during droughts or preventing damaging hail storms. The educational outreach components of the project are three-fold: the science of ice nucleation will be disseminated and taught to Appalachian high school students to broaden their definition of science, increase knowledge, and stimulate interest of possible scientific opportunities in their future; under-represented undergraduate students will participate in research programs; and graduate students will receive advanced training on ice nucleation, be mentored throughout their graduate school career, and produce data that can be disseminated via scholarly publications. The project will be evaluated by co-PI Dr. Tiffany Drape (ALCE) on its effectiveness to not only conduct the proposed research activities but its ability to train and disseminate information to the three target audiences.
