Plant stress physiology

Plant strees physiologyIBIMET investigates plant responses to different stress conditions (drought, heavy metal pollution, temperature, high irradiation, pathogens, etc.) at above and belowground plant level. Central to researching how these abiotic and biotic constrains affect plant physiology, in relation also to altered land use and climate changes.

Through a metabolomic approach IBIMET investigates the role of different endogenous molecules of the primary (carbohydrates, plant hormones, etc…) and secondary metabolism (VOC, xanthophylls, isoprenoids, etc…) as stress markers or signals in plant responses to environmental constrains as well as the cross-talk among different metabolic pathways in order to enhance our understanding how these stress factors affect those plant mechanisms and how plants discriminate among different environmental challenges in order to optimize the allocation of their resources to growth, defense, and reproduction. Understanding the complex physiological changes that occur in response to environmental constrains related also global changes such as high CO2 concentrations in functional terms, represent a difficult but intriguing challenge. Plant strees physiologyThe functional complexities of the plant defenses with physiological perspective at plant level also brought to investigate and study those relationship and processes at the spatial scale of the ecosystem level.
