Relation of Structure of 2,4-Dichloro-phenoxyacetate to its Mode of Action as an Auxin

Nature volume 180, pages 1365–1366 (1957)Cite this article

Abstract

Heath and Clark1 have proposed a possible mechanism for the mode of action of auxin which involves interference with metal ion metabolism. This conclusion was based on work involving the growth stimulation of wheat coleoptile sections. They found a particularly interesting relationship between many known chelators of various molecular structure and their ability to act as growth substances. These workers extended their findings on this relationship of chelators and growth stimulation with root-growth experiments2.
