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.

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of
