Weighing the options: a test of alternative stomatal optimisation models at high temperatures

New Phytologist, EarlyView.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

Beyond high‐throughput: leveraging plant phenotyping to improve understanding and prediction of plant growth through process‐based models

New Phytologist, EarlyView.
Summary The last decade has marked a period of rapid innovation in high‐throughput phenotyping (HTP) of plants. This includes the establishment of robotic phenotyping infrastructure, development of new sensors, and improvements in computation for downstream analysis.

Island influences on plant functional traits and trait–trait associations across species‐ and community‐scales

New Phytologist, EarlyView.
Summary The island rule predicts gigantism or dwarfism in body size of island species relative to their mainland counterparts. However, whether other functional traits shift and whether trait–trait associations on islands differ between species and community levels remains unclear. We measured 13 carbon‐ and water‐related functional traits in 37 shared

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

New Phytologist, EarlyView.
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.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, EarlyView.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Scaling plant hydraulic traits to predict ecosystem fluxes under drought

New Phytologist, EarlyView.
Summary Expanding plant hydraulic trait measurements and advances in hydraulic modeling have improved mechanistic predictions of water–carbon fluxes under drought. However, mismatches between individual‐scale traits and ecosystem‐scale model representations introduce prediction uncertainties and obscure how drought impacts propagate across scales. This
