Stress metabolism

Photosynthetic organisms are the basis of virtually all life on Earth. Plant growth and productivity are intricately affected by stress factors in their environment, impacting on agricultural crops and wild plant species alike. We study plant stress response, including to the stress factors related to climate change, such as drought and elevated temperature. We use chromatography and mass spectrometry (HPLC, LC-MS/MS and GC-MS), and non-invasive techniques (e.g., infrared thermography and chlorophyll fluorescence) to decipher biochemical mechanisms related to acclimation and adaptation of photosynthetic life-forms to challenging environments, using a broad array of models, including seeds, lichens, microalgae and vascular alpine plants.
