Mycorrhiza-Tree-Herbivore Interactions: Alterations in Poplar Metabolome and Volatilome.

ABSTRACT: Plants are continuously interacting with other organisms to optimize their performance in a changing environment. Mycorrhization is known to affect the plant growth and nutrient status, but it also can lead to adjusted plant defense and alter interactions with other trophic levels. Here, we studied the effect of Laccaria bicolor-mycorrhization on the poplar (Populus x canescens) metabolome and volatilome on trees with and without a poplar leaf beetle (Chrysomela populi) infestation. We analyzed the leaf and root metabolomes employing liquid chromatography-mass spectrometry, and the leaf volatilome employing headspace sorptive extraction combined with gas-chromatography-mass spectrometry. Mycorrhization caused distinct metabolic adjustments in roots, young/infested leaves and old/not direct
