Plant Advanced Technologies PAT announced the results of a study published in the American scientific journal, PNAS, of a new class of plant defense molecules equipped with biosynthesis mechanisms unknown to date. Aromatic O-prenyltransferases (O-PT): new enzymes with unsuspected powers: This discovery concerns a new class of enzymes identified in plants producing very original self-resistance mechanisms (O-prenylated substances). The discovery of these enzymes and the associated resistance mechanisms contribute to a better understanding of the immense chemical diversity contained in plants. A collaborative partnership with leading universities for a world first in the field of plant biochemistry: This work was carried out as part of a scientific collaboration between Plant Advanced Technologies PAT, the Agronomy and Environment Laboratory (LAE) of the University of Lorraine and the Laboratory of Plant Gene Expression, Research Institute for Sustainable Humanosphere of Kyoto University. This initiative was made possible through industrial contracts (LAE-PAT) and collaborative projects, BIOPROLOR2 (financed by the Grand Est region) and IMPACT Biomolécules (financed by the Lorraine University of Excellence (LUE) I-SITE program. A discovery with applications in all PAT’s markets: The potential applications of this discovery are very promising and provide Plant Advanced Technologies PAT and its subsidiaries with an additional biotechnology tool to create and produce new innovative active ingredients for its different markets (pharmaceuticals, cosmetics, nutraceuticals and crop protection).
