ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

open access: yes, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Diffusive and Metabolic Constraints to Photosynthesis in Quinoa during Drought and Salt Stress

open access: yesPlants, 2017
Quinoa (Chenopodium quinoa Willd.) has been proposed as a hardy alternative to traditional grain crops in areas with warm-to-hot climates that are likely to experience increased drought and salt stress in the future.

Interactions Between Carbon Metabolism and Photosynthetic Electron Transport in a Chlamydomonas reinhardtii Mutant Without CO2 Fixation by RuBisCO

open access: yesFrontiers in Plant Science, 2022
A Chlamydomonas reinhardtii RuBisCO-less mutant, ΔrbcL, was used to study carbohydrate metabolism without fixation of atmospheric carbon. The regulatory mechanism(s) that control linear electron flow, known as “photosynthetic control,” are amplified in ...

Influence of Inorganic Phosphate on Photosynthesis of Wheat Chloroplasts: II. RIBULOSE BISPHOSPHATE CARBOXYLASE ACTIVITY [PDF]

open access: yes, 2017
Isolated wheat chloroplasts were pre-incubated in the dark in the presence of various concentrations of inorganic phosphate with or without carbon dioxide, oxaloacetate, glycerate, and 3-phosphoglycerate.

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains

The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Cross-species analysis traces adaptation of Rubisco towards optimality in a low dimensional landscape

open access: yes, 2010
Rubisco, probably the most abundant protein in the biosphere, performs an essential part in the process of carbon fixation through photosynthesis thus facilitating life on earth.

Purification and Degradation of Ribulose Bisphosphate Carboxylase from Soybean Leaves [PDF]

open access: yesPlant Physiology, 1986
A rapid method is described for the preparation of up to 500 milligrams of pure ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBP carboxylase) from 250 grams of field-grown soybean leaves. Leaves were extracted in 20 millimolar phosphate (pH 6.9) at 4 degrees C, containing 4% (w/v) polyvinylpolypyrrolidone, 10 micromolar leupeptin, 1 millimolar ...

Potential drivers of fast growth in Paulownia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

Low irradiance alters carbon metabolism and delays flower stalk development in two orchids

open access: yesBiologia Plantarum, 2013
In Phalaenopsis, lowering irradiance has been used to delay flower stalk development but the accompanying biochemical changes remain poorly understood. We cultured two commercial Phalaenopsis-type orchids, Phalaenopsis cv.
