Summary Climate change is increasing insect pressure and forcing plants to adapt. Although chemotypic differentiation phenotypic plasticity in spatially separated tree populations are known for decades, understanding their importance herbivory resistance across forests remains challenging. We studied four oak forest stands Germany using nontarget metabolomics, elemental analysis, chemometrics mapped the leaf metabolome of herbivore‐resistant (T‐) herbivore‐susceptible (S‐) European oaks (...
Abstract Plants harbour a wide range of leaf‐feeding insects whose survival and fitness are influenced by both energy‐rich molecules phytochemicals in the host foliage. Yet, how leaf chemical diversity insect microbiota—key factors ecological physiological processes—impact nutrition still poorly understood. To study effects metabolic composition on herbivory resistance performance, we fed larvae specialist Tortrix viridana with leaves susceptible resistant Quercus robur trees that...
Infection of Arabidopsis with avirulent Pseudomonas syringae and exposure to nitrogen dioxide (NO2) both trigger hypersensitive cell death (HCD) that is characterized by the emission bright blue-green (BG) autofluorescence under UV illumination. The aim our current work was identify BG fluorescent molecules scrutinize their biosynthesis, localization, functions during HCD. Compared wild-type (WT) plants, phenylpropanoid-deficient mutant fah1 developed normal HCD except for absence...
5-Hydroxymethylfurfural (HMF), a Maillard reaction product, can be formed when honey is subjected to heat treatment or long storage time, becoming volatile and toxic depending on its concentration.
Abstract Metabolomics studies are becoming increasingly common for understanding how plant metabolism responds to changes in environmental conditions, genetic manipulations and treatments. Despite the recent advances metabolomics workflow, sample preparation process still limits high-throughput analysis large-scale studies. Here, we present a highly flexible robotic system that integrates liquid handling, sonication, centrifugation, solvent evaporation transfer processed 96-well plates...
Plants harbor a wide range of leaf-feeding insects. Insect survival and fitness are influenced by both energy-rich molecules phytochemicals in the host foliage. Yet, how leaf chemical diversity insect microbiota - key factors ecological physiological processes – shape nutrition impact performance is still poorly understood. Here we forced Tortrix viridana larvae, an oak-specialized herbivore, to feed on two Quercus robur susceptible resistant metabolic phenotypes (metabotypes) examined leaf,...
Ongoing global warming favors the spread of common ragweed ( Ambrosia artemisiifolia ) with impacts on human health due to its strongly allergenic pollen. Yet, impact future temperature scenarios pollen allergenicity has not been comprehensively studied. We chose two regions in Bavaria (Germany) an actual difference +1.5 °C summer Würzburg compared Munich, and experimentally simulated increase 4 °C. As these include urban environments, we also explored effects NO 2 .We assessed plant growth...
