Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Antisense reduction in NADP‐ME in the C4 species Flaveria bidentis alters stomatal sensitivity to intercellular [CO2]

New Phytologist, EarlyView.
Summary Stomata have the crucial role of balancing the uptake of CO2 for photosynthesis and water loss via transpiration by adjusting their aperture. In C3 plants, coordination between photosynthesis and stomatal conductance can be disrupted by mutations in Calvin–Benson–Bassham (CBB) cycle expression, but it is not clear whether the disruption of the ...

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.

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.

Biogeochemistry of phytoplankton RuBisCO in the ocean

Frontiers in Marine Science
Form I Ribulose-1,5-bisphosphate oxygenase/carboxylase (RuBisCO) is the most abundant enzyme on Earth, playing a key role in carbon fixation during oxygenic photosynthesis.

Metacaspases contribute to the cellular response to heat stress in a marine diatom

New Phytologist, EarlyView.
Summary Climate‐driven marine heatwaves (HW) are extreme, large‐scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance.

Heat Denaturation Profiles of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (Rubisco) and Rubisco Activase and the Inability of Rubisco Activase to Restore Activity of Heat-Denatured Rubisco

Plant Physiology, 1997
Abstract We compared the heat-denaturation profiles of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase and further examined the ability of Rubisco activase to restore the activity of heat-denatured Rubisco originally reported (E. Sanchez de Jimenez, L. Medrano, and E. Martinez-Barajas [1995] Biochemistry 34:

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.

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.

Fire Blight Management: Physiological Assessment of Cultural Control By Pruning in Pear Orchards

Agriculture, 2020
The aim of this work was to evaluate the photosynthetic performance of Pear trees (cv. ‘Rocha’) infected with Erwinia amylovora, three months after suffering a pruning of infected branches (P-trees) compared with asymptomatic trees (C-trees) of the same ...
