Too Many Binding Proteins, not Enough Receptors?

Those who originally sought plant hormone receptors in the late 1960’s were largely concerned with understanding the mechanism of action of the regulators. At that time, rapid progress was being made in discovering the basic mechanisms by which animal hormones acted and receptors for the major groups of animal hormones were being found. In the case of animal hormones, evidence as to the mechanism of action of the major groups of hormone was available and the receptors, as they were found, provided key pieces of a jigsaw which was fitting together nicely. Those working on the mechanism of action of plant hormones were having less success and the search for receptors was begun while their jigsaw pieces were still being roughly arranged. Researchers seeking plant hormone receptors reasoned that the isolation of plant hormone receptors would provide the key to the puzzle and expected that information about the receptors would lead to a breakthrough in discovering the mechanism of action of the individual hormones. This dream remained unfulfilled. Indeed it now seems possible that, rather than the isolation of plant hormone receptors leading us to the mechanism of action of the hormones, an increased understanding of the mechanism of action of the hormones may be needed to lead us to the receptors.
