Characterization of Novel Biomolecules Establishing Mutualistic Interactions with Roots of Arabidopsis and Nicotiana Species (A03)

• Subject Area: Plant Physiology ; Organismic Interactions, Chemical Ecology and Microbiomes of Plant Systems
• Term: from 2014 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 239748522

The root-colonizing fungi Piriformospora indica (Pi) und Mortierella hyalina (Mh) promote the fitness of plants. We study perception and early Ca2+-dependent signaling steps in Arabidopsis roots which are induced by the chemical mediators cellotriose from Pi, short-chain cello-oligomers, and a furan from Mh, which inform the plants about changes in their cell walls and the rhizosphere. Furthermore, the role of a S-containing volatile released by Mh and of a N2-fixing bacterium in Mh will be studied in the tripartite plant-fungus-bacterium interaction.
