Scots Pines With Tolerance to Melampsora pinitorqua and Diplodia sapinea Show Distinct Metabolic Profiles. [PDF]

Plant Cell Environ
Diplodia sapinea causes Diplodia tip blight (DTB) and is recognised as an opportunistic necrotrophic pathogen affecting conifers. While DTB is associated with abiotic stress, the impact of biotic stress in the host on D.

Biosynthesis of the Major Tetrahydroxystilbenes in Spruce, Astringin and Isorhapontin, Proceeds via Resveratrol and Is Enhanced by Fungal Infection     [PDF]

Plant Physiology, 2011
Abstract Stilbenes are dibenzyl polyphenolic compounds produced in several unrelated plant families that appear to protect against various biotic and abiotic stresses. Stilbene biosynthesis has been well described in economically important plants, such as grape (Vitis vinifera), peanut (Arachis hypogaea), and pine (Pinus species ...

Localization of (+)-Catechin in Picea abies Phloem: Responses to Wounding and Fungal Inoculation. [PDF]

Molecules, 2020
To understand the positional and temporal defense mechanisms of coniferous tree bark at the tissue and cellular levels, the phloem topochemistry and structural properties were examined after artificially induced bark defense reactions.

Insights into Molecular Interactions and Biological Effect of Natural Stilbenoids at the TRPA1 Ion Channel. [PDF]

ChemMedChem
Binding of the natural stilbenoids, isolated from Norway spruce and Scots pine, was analyzed at three known binding sites of transient receptor potential ankyrin 1 (TRPA1) using molecular docking and molecular dynamics (MD) simulations. Furthermore, bias‐force pulling simulations predicted a putative novel binding pocket for the stilbenoids, distinct ...

Lignin from Tree Barks: Chemical Structure and Valorization. [PDF]

ChemSusChem, 2020
Bark for good: Tree barks are low‐cost and abundant lignocellulosic wastes produced by the wood industries. This study concerns the detailed structural characterization of lignin from different tree barks, which will be of great help for the development of efficient conversion technologies of these materials and will aid in their full valorization. The

Tissue‐specific stilbene accumulation is an early response to wounding/grafting as revealed by using spatial and temporal metabolomics

Plant, Cell &Environment, Volume 46, Issue 12, Page 3871-3886, December 2023., 2023
Abstract Grafting is widely used in horticulture. Shortly after grafting, callus tissues appear at the graft interface and the vascular tissues of the scion and rootstock connect. The graft interface contains a complex mix of tissues, we hypothesised that each tissue has its own metabolic response to wounding/grafting and accumulates different ...

White wine phenolics: current methods of analysis

Journal of the Science of Food and Agriculture, Volume 103, Issue 1, Page 7-25, 15 January 2023., 2023
Abstract White wine phenolic analyses are less common in the literature than analyses of red wine phenolics. Analytical techniques for white wine phenolic analyses using spectrophotometric, chromatographic, spectroscopic, and electrochemical methods are reported.
