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

Phylloplanins

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.

Biodeterrents

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.



Bioproduction

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.
