The Plant Hormone Concept:Concentration, Sensitivity …

Abstract. The concept of control by changing concentrations is crucial to the original concept of hormones in mammals. A few years ago, a great stir was created amongst biologists working with plant hormones by the suggestion of Trewavas (56) that there is no evidence that plant hormones act via changes in the amount or concentration of the hormone, and that all change in response must be ...

Plant hormone - Wikipedia

Plant hormones (also known as phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations.Plant hormones control all aspects of plant growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development. Unlike in animals (in which hormone production is restricted to ...
