Project: Regulation of H+-transport proteins by regulatory protein kinases and phosphatases.

Main areas of interest: 

1) Isolation of regulatory proteins followed by reconstitution of complete signal transduction pathways in heterologous expression systems.

2) Identification of stimuli leading to in vivo phosphorylation of the PM H+-ATPase and identification of the sites by mass-spectroscopy.

3) Application of nano-sensors for in vivo detection of protons in plants.

Methods: Expertise within the area of protein-protein interactions, molecular biology, heterologous expression and and molecular plant physiology.
