The Role of Environmental Parameters in the Evolution of Holm Oak (Quercus ilex L. subsp. ballota (Desf.) Samp) Decline: Studies in the Iberian Peninsula

open access: yesForest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

open access: yesNew Phytologist, Volume 252, Issue 1, Page 178-191, October 2026.
Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7676-7691, October 2026.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

open access: yesPlant Biology, Volume 28, Issue 6, Page 2054-2064, October 2026.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.
