Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1143-1160, August 2026.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2168-2185, August 2026.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

Tomato plants control leaf sodium levels to limit damage by Spodoptera littoralis larvae

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3417-3427, June 2026.
Summary Sodium is an essential element for animal growth and survival. Here we test the hypothesis that plants exposed to insect feeding can translocate sodium from the feeding site to other plant organs as a defense strategy against phytophagous insects, which need sodium in their diet.

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 792-810, May 2026.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1460-1467, May 2026.
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.
