Rubisco evolution in C4 eudicots: an analysis of Amaranthaceae sensu lato [PDF]
, 2015 BACKGROUND Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyses the key reaction in the photosynthetic assimilation of CO₂. In C₄ plants CO₂ is supplied to Rubisco by an auxiliary CO₂-concentrating pathway that helps to maximize the ...

Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2
AMB Express, 2021 The oxygenase activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) converts ribulose-1,5-bisphosphate (RuBP) into 2-phosphoglycolate, which in turn channels into photorespiration, resulting in carbon and energy loss in higher plants.

Effect of salicylic acid pretreatment on cadmium toxicity in wheat
Biologia Plantarum, 2010 Cadmium (100, 400 and 1000 μM CdCl2) treatments resulted in the inhibition of root dry biomass, root elongation and increased Cd accumulation in wheat (Triticum aestivum L.) roots.

Effects of OsRCA Overexpression on Rubisco Activation State and Photosynthesis in Maize
Plants, 2023 Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize

Continuous artificial synthesis of glucose precursor using enzyme-immobilized microfluidic reactors
Nature Communications, 2019 Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is a difficult enzyme to work with. Here, the authors covalently immobilized it in a microfluidic reactor to enhance its storage/thermal stabilities and reusability, which enabled the continuous ...

Low Salinity Improves Photosynthetic Performance in Panicum antidotale Under Drought Stress
Frontiers in Plant Science, 2020 Salinity and drought are two often simultaneously occurring abiotic stresses that limit the production of food crops worldwide. This study aimed to distinguish between the separate and combined impacts of drought and salinity on the plant response ...

Competition of Pyridoxal 5'-Phosphate with Ribulose 1,5-Bisphosphate and Effector Sugar Phosphates at the Reaction Centers of the Spinach Ribulose 1,5-Bisphosphate Carboxylase/Oxygenase [PDF]
, 1980 The Stimulation of the carboxylase reaction by effectors of ribulose 1,5-bisphosphate carboxyl ase/oxygenase displays higher sensitivity towards pyridoxal 5'-phosphate inhibition than the catalytical process itself. Pyridoxal 5'-phosphate binding to the

Ribulose Bisphosphate Carboxylase [PDF]
Plant Physiology, 1977 A decaploid tall fescue (Festuca arundinacea Schreb) genotype has been found which exhibits net photosynthetic rates of 32 to 41 mg CO(2)/dm(2).hour as opposed to a mean of 22 mg CO(2)/dm(2).hour for 10 hexaploid genotypes. The decaploid genotype exhibited a ribulose 1,5-bisphosphate (RuBP) carboxylase specific activity 1.3- to 2-fold higher than ...

Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica
Frontiers in Microbiology, 2015 The Earth’s crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth’s surface.
