Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

open access: yesPlant, Cell &Environment, Volume 49, Issue 6, Page 3351-3362, June 2026.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Intrusive growth of sclerenchyma fibers [PDF]

open access: yes, 2010
Intrusive growth is a type of cell elongation when the rate of its longitudinal growth is higher than that of surrounding cells; therefore, these cells intrude between the neighboring cells penetrating the middle lamella.

How Large, Decayed, and Moist Must Rotting Logs Be to Act as Thermally Buffered Microhabitats in Temperate Eastern United States Forests?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study addresses the ecological role of coarse woody debris (CWD) as a thermally buffered microhabitat for saproxylic organisms in temperate eastern US forests. We measured internal and external log temperatures across four seasons in Southern Appalachian forests to test how log diameter, decay stage, and moisture influence thermal buffering.

Next‐Generation Sustainable Food Production Through Integrative Biotechnology, AI, and Climate‐Resilient Innovations

open access: yesFood and Energy Security, Volume 15, Issue 3, May/June 2026.
ABSTRACT By 2050, the global population is projected to reach ~10 billion, leading to 50% increase in food demand. This growth will place immense pressure on agricultural systems that are already struggling with the impacts of climate change and resource depletion.

Modeled Tracheidograms Disclose Drought Influence on Pinus sylvestris Tree-Rings Structure From Siberian Forest-Steppe

open access: yesFrontiers in Plant Science, 2018
Wood formation allows trees to adjust in a changing climate. Understanding what determine its adjustment is crucial to evaluate impacts of climatic changes on trees and forests growth.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1251-1269, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.
