Evidence for a trade‐off between growth rate and xylem embolism resistance in 22 Eucalyptus species

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2407-2426, September 2026.
Examples of cross‐sectional images of branchlets at 4× and 40×. Summary Within the growth–survival trade‐off framework, embolism resistance is considered a contributor to survival, yet whether greater embolism resistance inherently limits growth remains unclear.

The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3640-3655, September 2026.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Opening the black box: in situ imaging of arbuscular mycorrhizal fungal structures in soil using synchrotron‐based micro‐CT

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3687-3702, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) contribute to plant nutrient and water uptake via their extraradical hyphal networks. However, in situ methodologies to quantify architectural and morphological traits of these networks in soil are largely lacking, limiting our understanding of AMF‐mediated resource transport.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

RGF signaling bridges root development and nonlethal thermal stress adaptation

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2656-2671, September 2026.
Nonlethal high temperature inhibits root growth. Summary Roots adapt to growth‐restricting but nonlethal high temperatures. Although lethal heat shock and moderately elevated temperatures have been extensively studied, the effects of nonlethal thermal stress on root development remain unclear.

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3096-3110, September 2026.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

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

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3221-3237, September 2026.
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

On the relationship between root economics and plant hydraulic traits

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3289-3302, September 2026.
Conceptual summary figure showing the results of the relationships between aboveground plant hydraulic strategies and root economics space (RES) traits. Summary Drought stress constrains the productivity of terrestrial ecosystems and the distribution of plant species.

ERF transcription factor StPti5 is a regulator of endophyte community maintenance in potato

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1344-1360, August 2026.
Summary We have recently identified an ethylene response factor, StPti5, as a susceptibility factor that negatively regulates immune responses to diverse pathogens. Here, we investigated the role of StPti5 in the processes involved in the colonization of potato with beneficial organisms.
