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

Heterogeneous Responses of High‐Latitude Forest Productivity to Interannual Climate Variability

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Amplified warming has altered the phenology and structure of high‐latitude forests, yet their carbon uptake responses to environmental variations remain uncertain. Using satellite observations of solar‐induced chlorophyll fluorescence (SIF), we quantify interannual variations in growing‐season (GS) productivity of these forests and their ...

Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 993-1003, May 2026.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

LARCH, leverage, and long memory [PDF]

open access: yes, 2003
We consider the long memory and leverage properties of a model for the conditional variance of an observable stationary sequence, where the conditional variance is the square of an inhomogeneous linear combination of past values of the observable sequence, with square summable weights.

Frost Tolerance Increases With Plant Height Among Co‐Occurring Alpine Species in the Central Tibetan Plateau

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Frost tolerance (LT50) varies greatly among species coexisting in an alpine community. Taller plants are more frost‐tolerant, reversing the expected intra‐community pattern. Evidence for a frost survival trade‐off: avoidance in short plants vs. tolerance in tall plants.

Climate Change Alters Elevational Distribution Patterns of Cormus domestica Habitat

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study utilizes species distribution models to project the habitat shifts of Cormus domestica in Italy, predicting a substantial range reduction of 32%–68% by 2100 driven primarily by rising annual mean temperatures. The results indicate a significant shift of suitable habitats toward higher elevations, creating a scenario where the necessary ...

Assessing Larix principis-rupprechtii productivity and its determinants based on national forest inventory data in Hebei Province, China

open access: yesFrontiers in Forests and Global Change
Tree productivity is not only determined by stand structure, but also influenced by soil chemical properties, climate and topography. However, the relative importance of each indicator on larch (Larix principis-rupprechtii) productivity were uncertain ...

Gut Dysbiosis as a Shared Mechanism in Obesity and Hypertension: Exploring a Promising Therapeutic Avenue

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 3, May 2026.
This review synthesises current knowledge on gut microbiome involvement in obesity and hypertension, evaluates microbiome‐based therapeutic strategies, and identifies critical research gaps to guide future investigations aimed at mitigating the dual pandemics.

Screening and Functional Evaluation of Four Larix kaempferi Promoters

open access: yesPlants
Promoters are powerful tools for breeding new varieties using transgenic technology. However, the low and unstable expression of target genes is still a limiting factor in Larix kaempferi (Lamb.) Carr (Japanese larch) genetic transformation.
