Description
Summary:and are two well-known stem parasitic plant genera with reduced leaves and roots, inducing haustoria in their stems. Their similar appearance in the field has been recognized, but few comparative studies on their respective plant interactions are available. To compare their interactions, we conducted a metabolite analysis of both the and the interaction. We investigated the energy charge of the metabolites by UFLC (ultra-high performance liquid chromatography), and conducted GC-MS (gas chromatography-mass spectrometry) analysis for polar metabolites (e.g., saccharides, polyols) and steroids. The energy charge after parasitization changed considerably in but not in . changed its steroid pattern during the plant interaction, whereas did not. In the polar metabolite analysis, the laminaribiose increase after parasitization was conspicuous in , but not in . This metabolite profile difference points to different lifestyles and parasitic strategies.
