Changes in PEP Carboxylase, Rubisco and Rubisco activase mRNA levels from maize (Zea mays) exposed to a chronic ozone stress

Biological Research, 2007
We quantified the ozone impact on levels of Zea mays L. cv. Chambord mRNAs encoding C4-phosphoenolpyruvate carboxylase (C4-PEPc), ribulose-l,5-bisphosphate carboxylase/oxygenase small and large subunits (Rubisco-SSU and Rubisco-LSU, respectively) and ...

Revisiting the Temperature Dependence of the Photorespiratory CO₂ Compensation Point (Γ*). [PDF]

Plant Cell Environ
ABSTRACT Accurate estimation of the photorespiratory CO2 compensation point (Γ*) is essential for describing the balance between Rubisco carboxylation and oxygenation and for parameterising biochemical models of photosynthesis. Γ* and the rate of CO2 release in the light (DL) are commonly estimated using the Laisk method, based on measurements of net ...

Protein separation and characterization from Neochloris Oleoabundans [PDF]

, 2013
The work is aimed to separate and characterize proteins from Neochloris Oleoabundans. Studies in the field are required to look for sub-products for the lipids extraction from microalgae and make the process more economically feasible.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

Plant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

Analysis of two rubisco-deficient tobacco mutants, h7 and sp25; evidence for the production of rubisco large subunits in the sp25 mutant that form clusters and are inactive

, 1993
The basis for the lesions in the Sp25 and H7 ribulose-l,5-bisphosphate carboxylase/oxygenase (Rubisco) mutants of tobacco was studied in detail because these plants may be suitable hosts for transformation with the genes for Rubisco enzymes of various ...

Multi‐Subunit Engineering of Photorespiratory Glycine Decarboxylase Refines Photosynthesis, Growth and Metabolic Robustness of Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Photorespiration secures oxygenic photosynthesis from metabolic constraints arising from the oxygenation reaction of Rubisco in today's oxygen‐rich atmosphere. Beyond this protective function, it is vital for primary metabolism, cellular redox balance, and stomatal regulation.

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...
