Effects of Heat Treatment on Durability of Merbau Heartwood
BioResources, 2015 Merbau wood has been widely used in outdoor applications. However, it has a disadvantage in that its water-soluble extractives readily leach out and stain adjacent materials. Heat treatment is an efficient technique to solve this problem.

Global Change Biology, Volume 32, Issue 7, July 2026.Rising atmospheric CO2 increases phosphorus demand in Amazon forests. Using a microbial‐explicit land model in low and high phosphorus Amazonian forest sites, we show that low‐phosphorus forests increasingly rely on organic phosphorus cycling to sustain productivity.

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

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.

Advances in the Study of Heartwood Formation in Trees. [PDF]
Life (Basel)Heartwood, serving as the central constituent of the xylem, plays a crucial role in the growth, development, and resilience of trees. The process of heartwood formation constitutes a complex biological phenomenon influenced by various factors. A thorough examination of the mechanisms underpinning heartwood formation not only enhances our understanding ...
