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.

Concurrent Temperature and Light Intensity Fluctuations Promote Stomatal Opening and Non‐Steady State Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT In nature, fluctuations in light intensity (FL) are tightly coupled to rapid changes in leaf temperature (Tleaf), yet the short‐term physiological effects of these concurrent drivers remain largely unresolved. Here, we combined rapid infrared induced Tleaf fluctuations with controlled step changes in light intensity for leaf gas exchange ...

Down-regulation of wheat Rubisco activase isoforms expression by virus-induced gene silencing [PDF]

Rubisco activase (Rca) is an essential photosynthetic enzyme that removes inhibitors from the catalytic sites of the carboxylating enzyme Rubisco. In wheat, Rca is composed of one longer 46 kDa α-isoform and two shorter 42 kDa β-isoforms encoded by the ...

Genomic and Physiological Insights Into Heat–Drought Tolerance in Wheat Through GWAS and Phenotypic Evaluation

Plant, Cell &Environment, EarlyView.
ABSTRACT Climate change‐driven heat and drought stresses during reproductive stages significantly threaten wheat productivity. To investigate the genetic and physiological basis of combined heat–drought (HD) tolerance, we evaluated 345 wheat genotypes under three environments of HD stresses, non‐stress glasshouse conditions and a late‐sowing field ...

High-resolution structure of the heat-stable form-IAq RuBisCO from the thermophilic purple sulfur bacterium Thermochromatium tepidum

Scientific Reports
Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the initial carbon fixation reaction in the Calvin-Benson-Bassham cycle. Among the many forms of RuBisCOs, form-I—a protein complex containing 8 large and 8 small subunits—is the most ...

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Genetic manipulation of Rubisco : chromatium vinosum rbcL is expressed in Nicotiana tabacum but does not form a functional protein

, 2002
N. tabacum lines that lacked functional Rubisco were transformed with plasmids encoding a chloroplast transit peptide in frame with C. vinosum rbcL and stable transformants generated.

Shigella Effector VirA Suppresses Plant Immunity by Compromising PRA1.F3‐Dependent Accumulation of FLS2 at the Plasma Membrane

Plant, Cell &Environment, EarlyView.
ABSTRACT Surface immune receptors such as flagellin‐sensitive 2 (FLS2) are critical for plant defence, and their accumulation at the plasma membrane is tightly controlled by the endomembrane system. Here, we identify the Arabidopsis thaliana prenylated Rab acceptor PRA1.F3 as a positive regulator required for efficient accumulation of FLS2 at the ...

A Water‐Saving Drought Survival Phenotype in a Wheat TILLING Mutant Involves Survival‐Biased Metabolic and Phosphorylation Reprogramming

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought tolerance in crops often involves trade‐offs between water conservation, growth and reproduction. Understanding how water‐saving strategies are implemented at physiological and metabolic levels remains critical for improving crop performance under water‐limited conditions.

The localisation of 2-carboxy-D-arabinitol 1-phosphate and inhibition of Rubisco in leaves of Phaseolus vulgaris L

, 1999
A recent controversial report suggests that the nocturnal inhibitor of Rubisco, 2-carboxy-D-arabinitol 1-phosphate (CA1P), does not bind to Rubisco in vivo and therefore that CA1P has no physiological relevance to photosynthetic regulation.
