Project description
 

Gradients in phloem turgor and osmotic pressure will be measured by aphid stylets in herbaceous species and trees. Both the magnitude of these gradients and their response to changing environmental conditions (light/dark and drought stress) will be quantified. Finally, the gradient dynamics will be related to the overall plant behaviour by applying a mechanistic model describing carbon and water transport.
