We envision a future that doesn’t require toxic chemicals to protect our food or our crops. At PhylloTech, we are working toward that vision by developing innovative biopesticides that inhibit diseases but limit environmental impact. We also envision a future where everything from industrial materials to biopharmaceuticals can be made by plants.
Biopesticide Pipeline – Enzymes in Ag
PhylloTech’s core technology is based on our discovery that some plants secrete defensive proteins termed phylloplanins. This novel family of secreted plant proteins inhibit a broad range of agricultural pathogens. Our scientists have published reports on phylloplanin effectiveness and the results of their endeavors are clear: phylloplanins are extremely effective, broad-spectrum pathogen controls. We believe these antimicrobial proteins are the next generation of environmentally-friendly biofungicides and genetic crop traits to enhance disease resistance.
Quorum sensing is a biochemical process that allows bacterial populations to coordinate gene expression and plays a significant role in the onset of pathogenesis and biofilm development. PhylloTech is currently developing environmentally-friendly methods to interrupt this process and limit the impact of bacterial pathogens on crop diseases.
Over the past few decades, discoveries in plant biology have enabled the production of heterologous proteins in plants and have opened the possibility to produce high-value proteins that are too difficult or costly to make in other systems. Plant-based protein expression systems are environmentally-friendly production methods with unlimited scalability. At PhylloTech, we use patented technology to produce high-value proteins such as antibodies and enzymes in plant trichomes.

Silke Robatzek Ph.D.; Professor, The Sainsbury Laboratory, Norwich UK. Professor Robatzek is a well-known scientist who specializes in plant-microbe interactions. Her current work elucidates the mechanisms by which plants transport proteins in response to pathogen attack, and identifies the biochemical cargoes and molecular switches involved in transport-regulated plant immunity. She also studies the cellular transport pathways that are modulated by pathogen attack, and has authored numerous publications in leading plant science and plant pathology journals.
Julian Schroeder Ph.D.; Professor, University of California San Diego. Studied at the Max Planck Institute for Biophysical Chemistry with Erwin Neher and was a von Humboldt postdoctoral fellow at UCLA School of Medicine. He received awards, including the Presidential Young Investigator Award (NSF), the ASPB Charles Albert Shull Award (1997), a DFG Heinz-Maier-Leibnitz Prize, the Blasker Award in Environmental Science, is Churchill Overseas Fellow at Cambridge University and with collaborators shared the Cozzarelli Prize from PNAS (2010) and a top 10 breakthrough of the year selected by Science (2009). He is a member of the U.S. National Academy of Sciences and Fellow of the American Association for the Advancement of Science. He has served on several advisory boards, is Co-Director of the UCSD Food and Fuel for the 21st Century Center. He was von Humboldt Fellow at the Max Planck Institute for Biochemistry and visiting Professor at the ETH Zurich.
