Species delimitation within the Achnanthidium minutissimum complex (Bacillariophyta), based on morphological, molecular, and ecophysiological approaches

Journal of Phycology, EarlyView.
Abstract The benthic diatom species Achnanthidium minutissimum belongs to a species complex with a challenging taxonomy. Achnanthidium minutissimum has been reported to be a widespread and abundant species occurring in a broad range of freshwater habitats. However, differentiating and delimiting it from other Achnanthidium species is challenging due to

Fulvic Acid Enhances Oat Growth and Grain Yield Under Drought Deficit by Regulating Ascorbate–Glutathione Cycle, Chlorophyll Synthesis, and Carbon–Assimilation Ability

Agronomy
Drought deficit inhibits oat growth and yield. Fulvic acid (FA) can enhance plant stress tolerance, but its effects on regulating the ascorbate–glutathione cycle, chlorophyll synthesis, and carbon–assimilation ability remain unclear.

Strategies for modulation and optimization of the photorespiration pathway in plants

浙江大学学报. 农业与生命科学版, 2020
Plant ribulose-1, 5-bisphosphate carboxylase/oxidase (Rubisco) has two activities, and the one is carboxylation to assimilate CO2 to produce food for the biosphere, and the other one is oxidation to generate toxic 2-phosphoglycolate to commit the ...

X-ray structure of Galdieria Rubisco complexed with one sulfate ion per active site [PDF]

, 2002
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the reactions of carboxylation and oxygenation of ribulose-1,5-bisphosphate. These reactions require that the active site should be closed by a flexible loop (loop 6) of the large ...

Covalent dimerization of ribulose bisphosphate carboxylase subunits by UV radiation [PDF]

Biochemical Journal, 1996
The effect of UV radiation (UV-A, UV-B and UV-C) on ribulose bisphosphate carboxylase from a variety of plant species was examined. The exposition of plant leaves or the pure enzyme to UV radiation produced a UV-dependent accumulation of a 65 kDa polypeptide (P65).

Stronger expression of crassulacean acid metabolism (CAM) requires effective cuticular transpiration barriers but not necessarily strong succulence

New Phytologist, EarlyView.
Summary Discovering functional and evolutionary interdependencies of hydraulic traits and crassulacean acid metabolism (CAM) is crucial to understand CAM phenotype diversity and convergence. In complex traits such as CAM, the co‐option of associated traits strongly impacts the evolutionary outcome.

Synechocystis PCC 6803 overexpressing RuBisCO grow faster with increased photosynthesis

Metabolic Engineering Communications, 2017
The ribulose-1,5-bisphosphate (RuBP) oxygenation reaction catalyzed by Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is competing with carboxylation, being negative for both energy and carbon balances in photoautotrophic organisms. This makes

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]

, 1988
An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...

Ribulose bisphosphate carboxylase/oxygenase in toluene-permeabilized Rhodospirillum rubrum [PDF]

Biochemical Journal, 1983
Toluene-permeabilized Rhodospirillum rubrum cells were used to study activation of and catalysis by the dual-function enzyme ribulose bisphosphate carboxylase/oxygenase. Incubation with CO2 provided as HCO3-, followed by rapid removal of CO2 at 2 degrees C and subsequent incubation at 30 degrees C before assay, enabled a determination of decay rates of
