Future heatwave conditions inhibit CO2‐induced stomatal closure in wheat

New Phytologist, Volume 249, Issue 3, Page 1234-1252, February 2026.
Summary As global temperatures and the severity of droughts continue to increase, food crops will more frequently experience high vapour pressure deficit (VPD) during heatwave events. However, the interactive effects of rising atmospheric CO2 and high‐VPD heatwaves on crop water fluxes and yields are currently unknown.

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

New 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 ...

Loss of E3 ligase HvST1 function substantially increases distal crossover frequency

New Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.
Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.

Fine‐tuning the buzz: comparing visitation frequency and pollination effectiveness in plant–pollinator networks

New Phytologist, Volume 249, Issue 4, Page 2140-2152, February 2026.
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
