Methabolism of methanol in plant organisms is considered in the paper. Enzymes of consecutive oxidation of methanol and enzymes responsible for incorporation of carbon from methanol molecule to methyl groups of phospholipids, carboxylic acids and carbohydrates have been described. The peculiarity of plant organisms is in interaction of reactions of methanol transformation with pathways of photorespiration and C₁-metabolism and in the capacity to use methanol carbon to form organic matter through photosynthesis. The inclusion of methanol metabolites in anabolic processes occurs at the level of formaldehyde and formiate. As a result, exogenous methanol at low concentrations can stimulate the photosynthetic efficiency of plants.
