A Common Fungal Associate of the Spruce Bark Beetle Metabolizes the Stilbene Defenses of Norway Spruce1[C][W][OA]
Stilbenes, a group of phenolic compounds found in Norway spruce bark with a diaryl-ethene skeleton with known antifungal properties, were investigated and showed that rapid conversion of host phenolics is associated with higher virulence.
Distinct pharmacological properties of morphine metabolites at G(i)-protein and β-arrestin signaling pathways activated by the human μ-opioid receptor.
CYP76C1 (Cytochrome P450)-Mediated Linalool Metabolism and the Formation of Volatile and Soluble Linalool Oxides in Arabidopsis Flowers: A Strategy for Defense against Floral Antagonists[OPEN]
Evidence is provided that CYP76C1 is a multifunctional enzyme that catalyzes a cascade of oxidation reactions and is the major linalool metabolizing oxygenase in Arabidopsis flowers and contributes to reduced floral attraction and favor protection against visitors and pests.

The results suggest the presence of different heterodimeric IPMIs in Arabidopsis chloroplasts with distinct substrate specificities for Leu or glucosinolate metabolism determined by the nature of the different small subunit.
Gene Coexpression Analysis Reveals Complex Metabolism of the Monoterpene Alcohol Linalool in Arabidopsis Flowers[W][OPEN]
This work characterizes two cytochrome P450s and two monoterpene synthases that are coexpressed in flowers and thus predicted to be involved in monoterpenoid metabolism. The results show that despite…
The role of glucosinolates and the jasmonic acid pathway in resistance of Arabidopsis thaliana against molluscan herbivores
The data highlight the function of well‐known antiherbivore defence pathways in resistance against slugs and snails and suggest an important role for the diurnal regulation of defence metabolites against nocturnal molluscan herbivores.

It is shown that cellotriose (CT) is an elicitor-active cell wall moiety released by P. indica into the medium that induces a mild defense-like response, including the production of reactive oxygen species, changes in membrane potential, and the expression of genes involved in growth regulation and root development.
Blumenols as shoot markers of root symbiosis with arbuscular mycorrhizal fungi
It is shown that shoot accumulations of hydroxy- and carboxyblumenol C-glucosides mirror root AMF-colonization in Nicotiana attenuata plants and that specific leaf-metabolites provide broadly applicable accurate proxies of these associations, suitable for HTP-screens.
