Root Cap and Georeaction

Nature New Biology volume 233, pages 115–116 (1971)Cite this article

Abstract

THE clear boundary1 between the cap and root proper in maize, enable assays such as those of Juniper et al.2 to be made. They found that removing the cap (decapping) prevented the perception of the gravitational stimulus although the root continued to elongate3; geosensitivity is regained when the cap is regenerated by the cap meristem. This suggested that the root cap might be the site of geoperception4–6 and the source of growth regulating compounds7.
