Phosphoproteome of arbuscular mycorrhiza
Scientific question
Which proteins are phosphorylated during the formation of arbuscular mycorrhizal (AM) symbiosis and to what extent are phosphorylation patterns conserved between distantly related crops?
Approach
Comparison of the AM-induced phosphoproteome between representatives of the rosids (pea), asterids (tomato) and commelinids (rice). Subsequent molecular and cell biological characterization of conserved and differentially phosphorylated candidate proteins.
Expected results
Capture of previously largely unknown signal transduction events that regulate AM symbiosis. The comparative approach will provide insights into conservation and differences between plant classes.
