Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, EarlyView.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

Plant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Fully Tunable Phosphorylation of RPS6A Ensures the Successful Development of Arabidopsis Seedlings

Plant, Cell &Environment, EarlyView.
ABSTRACT Light enhances protein translation, enabling young seedlings to rapidly and timely acquire photosynthetic capacities. Sequential phosphorylation of ribosomal protein S6 (RPS6) was implicated in the light‐enhanced translation; however, the exact phosphorylation sites and the biological relevance of RPS6 multi‐phosphorylation in seedling ...
