Stress responses

The model plant Arabidopsis is used to study low temperature acclimation. Top-plant grown at 23C, bottom-plant gorwn at 5C.
Stress is any environmental factor (both abiotic and biotic) that is unfavourable for plant growth and survival. In most cases, stress induces adaptive responses, which increase the probability of surviving the unfavourable conditions. We wish to understand the underlying mechanisms responsible for these responses when plants acclimate to their new environment. In the long term, such knowledge will be vital for eventually altering the stress tolerance and growth characteristics of selected plants. A range of plant stress responses is elucidated within our UPSC program, including adaptations to extreme temperatures (mainly low temperatures), high light (photoinhibition) and nutrient limitations. In a new project we also address patogen interactions. In many of these situations oxidative stress is an important component. Repair mechanisms involved in stress damage control and recovery are also studied. The new techniques of functional genomics open up new and exciting possibilities to study the interaction of plants with their environment.
