Comparative Investigations on the Metabolism of the Herbicide 2-(2,4-Dichlorophenoxy)-propionic Acid in Plants and Cultured Cells of Tomato

Abstract

Abstract Akademie der Wissenschaften der DDR , Institut für Biochemie der Pflanzen, Weinberg 3, Halle/Saale. The metabolism of [1-14C]2-(2,4-dichlorophenoxy)-propionic acid was studied in excised plants and cell suspension cultures of tomato. It was rapidly taken up and metabolized by both the plants and the cultured cells. The metabolites, isolated by extraction with aqueous acetone, separated and purified by TLC and HPLC, were identified by chemical and spectrometric methods. Conjugates with carbohydrates were detected. Glucose, diglucose as the main conjugating moiety, and triglucose were found as carbohydrate components within the conjugates. Almost the same conjugates occurred in plants and cultured cells.
