Invasive plants optimize leaf nitrogen allocation in photosynthesis

New Phytologist, EarlyView.
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.

Diversity affects microclimate temperature and humidity: an overview of the evidence and major unanswered questions

New Phytologist, EarlyView.
Summary Climate change is increasing global temperatures, increasing atmospheric drying, and driving more severe and frequent drought. Plants can cool and humidify microclimates through sensible and latent heat exchange. Higher diversity plant communities can modify microclimates more strongly than lower diversity plant communities, creating the ...

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.

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.

Arabidopsis acclimation to daily environmental fluctuations converts a defense response regulator into a susceptibility factor toward Sclerotinia

New Phytologist, EarlyView.
Summary Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the acclimation of Arabidopsis thaliana quantitative immune responses against the fungal pathogen Sclerotinia sclerotiorum to daily environmental ...

Soil phosphorus drives subcontinental patterns of carbon isotope discrimination across Australia

New Phytologist, EarlyView.
Summary Several transects have been established to study the sensitivity of carbon isotope discrimination (Δ13C) in woody plants to mean annual precipitation (MAP) across Australia. These have shown a surprising divergence in Δ13C‐MAP sensitivity among subcontinental regions.

Aridity and drought: distinct concepts often conflated in ecological research

New Phytologist, EarlyView.
Summary As well‐established drivers of ecological pattern and process, aridity and drought are linked by a common focus on water limitation – with both aridity and especially drought projected to increase in extent and severity with climate change. There is a long history of assessing plant adaptations to drought through the lens of aridity. Consistent

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, EarlyView.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...
