Research interests

Plasma membrane properties and signal transduction in plant cells under abiotic stress
When plants are subjected to different types of abiotic stress, such as salt, cold, anoxia and heavy metals, the stress induces a fast, often transient, increase in calcium concentration in the cell cytosol. The change in cytosolic Ca2+ is often correlated with a change in cytosolic pH, as well as with different phosphorylation and dephosphorylation reactions. We are investigating the initial reactions caused by salt, anoxia and heavy metal stress in plants, sensitive and tolerant to these types of stress. The aim is to clarify the mechanisms behind the primary reactions and how the plant can recognize the different types of stress. Cytosolic ion concentrations are detected by fluorescent dyes and fluorescence microscopy. The program also concerns acclimation processes taking part in the plasma membrane, such as effects of salt and oxygen deficiency on ATPase activity and lipid composition. In the salt and heavy metal projects molecular techniques are used to clarify the role of different transporter genes involved in the tolerance mechanisms.
