Discovery of pseudobaptigenin synthase in fungal‐infected Trifolium pratense roots

The Plant Journal, Volume 127, Issue 1, July 2026.
Significance Statement The discovery of pseudobaptigenin synthase in red clover (CYP76F319), catalyzing the formation of a methylenedioxy bridge to convert calycosin to pseudobaptigenin. The integration of metabolomic and transcriptomic datasets to describe the defense response in red clover roots to hemibiotrophic and necrotrophic fungi.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence

Oikos, Volume 2026, Issue 6, June 2026.
Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

New Insights on Wood Dimensional Stability Influenced by Secondary Metabolites: The Case of a Fast-Growing Tropical Species Bagassa guianensis Aubl. [PDF]

PLoS ONE, 2016
Challenging evaluation of tropical forest biodiversity requires the reporting of taxonomic diversity but also the systematic characterization of wood properties in order to discover new promising species for timber industry.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Chemical changes of polysaccharides in heat-treated European beech wood

Journal of Wood Science
This work deals with the influence of different heat treatment temperatures (140, 150, 160, 170, 180, 190, 200, and 210 °C) on changes in sapwood and red heartwood of European beech (Fagus sylvatica L.). According to the results of wet chemistry methods,

Concentration and Distribution of Nuclei and Plastids in Xylem Cells in Cunninghamia lanceolata and Aquilaria sinensis

BioResources, 2015
After programmed cell death (PCD), heartwood formation, storage, and processing, wood DNA degradation occurs to varying degrees. The concentration and distribution of nuclei and plastids in xylem cells of Cunninghamia lanceolata and Aquilaria sinensis ...

Spatial Distribution and Conservation Prioritization of Medicinal Gymnosperms in China Using an Optimal Set‐Cover Approach

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The study identified 41 priority conservation grids and 8 critical conservation gaps not covered by national reserves for medicinal gymnosperms. We proposed a practical, multi‐dimensional framework for their conservation. ABSTRACT To elucidate the geographical distribution patterns and hotspots of medicinal gymnosperms in China, providing a scientific ...

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

Food Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...
