Ebook: Plant Hormone Receptors

The Nato Advanced Research Workshop on Plant Hormone Receptors was held at the Physik Zentrum in Bad Honnef near Bonn, August 18-22, 1986. This workshop was mainly supported by the Nato Scientific Affairs Division and additionally cosponsered by Hoechst AG, Frankfurt and BASF AG, Ludwigshafen. The workshop aimed at focusing research on plant hormone recep­ tors. It should provide an opportunity to all who work in this field to report on their very recent data and to discuss their results with the most competent' colleagues. The total number of participants was limited to 30 to ensure personal contact and intensive discussions. Everyone had to either give a lecture or practical course. One half of the participants were invited, the other was selected by applications. Plant hormone receptors are assumed to exist but clear results are still rare. Nevertheless encouraging results have been published over the last years. Receptors for animal hormones and neuronal transmitters are well characterized, both structu­ rally and functionally. Therefore scientists dealing with recep­ tors for steroid hormones - Prof. E.E. Baulieu, Paris and Prof. J. R. Gustafsson, Huddinge - and for acetylcholine - Prof. A. Maelicke, Dortmund - were invited to participate in the workshop.
