Chemical relationship between Pinaceae [PDF]

open access: yesBiochemical Systematics and Ecology, 1980
Fingerprints of phenolic compounds of leaf extracts of eleven pine species have been made by paper chromatography and HPLC. The results suggest a chemical relationship which agrees fairly well with those based on immunological and morphological characters but not always with the classification commonly used.

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees

open access: yesNew Phytologist, EarlyView.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

The relative ages of ectomycorrhizal mushrooms and their plant hosts estimated using Bayesian relaxed molecular clock analyses

open access: yesBMC Biology, 2009
Background Ectomycorrhizae (ECM) are symbioses formed by polyphyletic assemblages of fungi (mostly Agaricomycetes) and plants (mostly Pinaceae and angiosperms in the rosid clade).

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Image Databases for Pollen Grain Classification: Availability, Quality, and Challenges

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 3, September 2026.
Overview of the study process, from identifying gaps in pollen image databases to a systematic search across six libraries, resulting in 73 final studies, 18 datasets (10 public), and a seven‐point standardization framework proposed under FAIR principles.

Global population structures and demographic history of Suillus luteus, a pine co‐introduced ectomycorrhizal fungus associated with exotic forestry and invasion

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2964-2979, September 2026.
Global phylogenomic tree and phylogenetic network of Suillus luteus and its closely related species. Summary Human colonization since the 19th century has resulted in the global spread of pines beyond their original northern boreal distribution. Although the introduction history of pines is documented through historical records, little is known about ...

Species Turnover and Environmental Filtering Structure Plant Communities in Moist Temperate Forests

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Plant biodiversity in moist temperate mountain forests is strongly structured by elevational and edaphic gradients that drive community differentiation over short spatial scales. Using integrated vegetation classification, diversity partitioning, and multivariate analyses, we show that species turnover, rather than nestedness, dominates beta diversity,

Facilitation influences when trees grow, but not growth rate in a dry temperate forest

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2668-2684, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately predicting the role of forests in the global carbon cycle requires a detailed understanding of the factors mediating the timing and magnitude of radial stem growth. While weather conditions and topo‐edaphic factors play a critical role in mediating short‐term
