Fig. 8From: Isoprene emission by poplar is not important for the feeding behaviour of poplar leaf beetlesGenotype-, time- and herbivore feeding-dependent metabolic changes both in the infested and adjacent undamaged leaves. Comparison of the metabolomics between infested (young) and adjacent undamaged (old) leaves in isoprene emitting (IE) and non-emitting (NE) poplar on the days 4, 8 and 14 after the release of Chrysomela populi. Hierachical clustering analysis of FT-ICR/MS intensities of all discriminant masses (a). The Venn plot shows the annotated discriminant metabolites of infested young and old leaves in IE (b) and NE plants (c). The metabolite annotations are shown in the bar chart ordered according to compound classes, pathways and poplar genotypes (d).
