Biomimetic chloroplasts: Two‐phase microfluidic platforms with selective permeability for artificial photosynthesis

Droplet, EarlyView.
We present a biomimetic chloroplast system that integrates light‐dependent and light‐independent reactions, reaction compartments, and selectively permeable interfaces using a biphasic microfluidic droplet platform. This system enables continuous substrate–product exchange, mitigating product inhibition and side reactions, thus enhancing reaction ...

Enhancing photosynthetic CO2 fixation by assembling metal-organic frameworks on Chlorella pyrenoidosa

Nature Communications, 2023
The CO2 concentration at ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is crucial to improve photosynthetic efficiency for biomass yield. However, how to concentrate and transport atmospheric CO2 towards the Rubisco carboxylation is a big ...

Cysteine proteinases regulate chloroplast protein content and composition in tobacco leaves: a model for dynamic interactions with ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) vesicular bodies.

Journal of Experimental Botany, 2008
The roles of cysteine proteinases (CP) in leaf protein accumulation and composition were investigated in transgenic tobacco (Nicotiana tabacum L.) plants expressing the rice cystatin, OC-1.

Ribulose 1,5-Bisphosphate Carboxylase Synthesis during Heat Shock [PDF]

Plant Physiology, 1985
Ribulose 1,5-bisphosphate carboxylase (RuBPCase) was chosen as a model protein to study how heat shock (HS) affects both chloroplast protein synthesis and the nuclear-chloroplast interaction in production of chloroplast proteins. Experiments were performed using highly chlorophyllous, soybean (Glycine max L. Merr.

A low oxygen threshold for physiological responses and trace metal quotas of Prochlorococcus and Synechococcus

Limnology and Oceanography, EarlyView.
Abstract Continued human activity is expected to accelerate ocean deoxygenation, leading to the expansion and shallowing of oxygen‐deficient zones (ODZs). This decline in oxygen may impact both phytoplankton growth and trace metal uptake. We conducted culture experiments with Prochlorococcus MIT9313 and Synechococcus XM‐24, two numerically dominant ...

Structure of the Calvin-Benson-Bassham sedoheptulose-1,7-bisphosphatase from the model microalga Chlamydomonas reinhardtii

eLife
The Calvin-Benson-Bassham cycle (CBBC) performs carbon fixation in photosynthetic organisms. Among the eleven enzymes that participate in the pathway, sedoheptulose-1,7-bisphosphatase (SBPase) is expressed in photo-autotrophs and catalyzes the hydrolysis

Inhibition and acclimation of photosynthesis to heat stress is closely correlated with activation of ribulose-1,5-bisphosphate Carboxylase/Oxygenase

Plant Physiology, 1999
Increasing the leaf temperature of intact cotton (Gossypium hirsutum L.) and wheat (Triticum aestivum L.) plants caused a progressive decline in the light-saturated CO2-exchange rate (CER).

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, EarlyView.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Regulation of Leaf Senescence by Cytokinin, Sugars, and Light. Effects on NADH-Dependent Hydroxypyruvate Reductase [PDF]

, 1998
The aim of this study was to investigate the interactions between cytokinin, sugar repression, and light in the senescence-related decline in photosynthetic enzymes of leaves. In transgenic tobacco (Nicotiana tabacum) plants that induce the production of
