Plant Growth Substances: sensitivity vs signal strength
We aim to discover how changes in development are controlled. Sometimes a shift in the level of active hormone is responsible, sometimes an alteration in the ability of the tissue to respond, more often a combination of both. We determine changes in signal strength by microanalysing tissues for hormones. We monitor sensitivity by investigating the activity of the components of signal transduction: receptors, secondary messengers and transcription factors. We are currently most interested in the cytokinins, and in inositol hexakisphosphate as a secondary messenger, but we are also working with abscisic acid, gibberellins, and the ERF/AP2 transcription factors.
