Phosphorylation of chloroplast ribulose bisphosphate carboxylase/oxygenase small subunit by an envelope-bound protein kinase in situ [PDF]

open access: yes, 1983
A new protein kinase of the cAMP independent type was found to be bound to the outer envelope membrane of spinach chloroplasts. While stimulated by Mg2+ and inhibited by ADP, the enzyme showed no response to conventional protein substrates and was ...

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

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

open access: yesNature 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 ...

The protein import apparatus of chloroplasts [PDF]

open access: yes, 1993
Routing of cytosolically synthesized precursor proteins into chloroplasts is a specific process which involves a multitude of soluble and membrane components.

Rubisco Activase Mediates ATP-Dependent Activation of Ribulose Bisphosphate Carboxylase [PDF]

open access: yesPlant Physiology, 1987
The activation level of ribulosebisphosphate carboxylase following preincubation with ribulose 1,5-bisphosphate was increased by ATP and ribulosebisphosphate carboxylase activase in the absence of thylakoids or illumination. Maximal activation was obtained with 0.5 millimolar ATP in the presence of an ATP regenerating system (phosphoenolpyruvate and ...

Effects of Cobalt and Zinc Stress on Rehmannia glutinosa Growth, Bioactive Compounds, Antioxidant Activity, and Molecular Insights

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
This study aimed to investigate the effects of cobalt (Co) and zinc (Zn) on the growth, antioxidant activity, total phenolic and flavonoid contents (TPC and TFC), targeted polyphenolic compounds, and molecular dynamics simulations of Rehmannia glutinosa (R. glutinosa) L.

Purification of Rubisco from Chlamydomonas reinhardtii

open access: yesBio-Protocol, 2015
Chlamydomonas reinhardtii is a model organism for chloroplast studies. Besides other convenient features, the feasibility of chloroplast genome transformation distinguishes this unicellular alga as ideal for the manipulation of chloroplastic gene ...

The regulation of the air: a hypothesis [PDF]

open access: yesSolid Earth, 2012
We propose the hypothesis that natural selection, acting on the specificity or preference for CO<sub>2</sub> over O<sub>2</sub> of the enzyme rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase), has controlled the CO<sub ...

Functional and mutational analysis of the light-harvesting chlorophyll a/b protein of thylakoid membranes. [PDF]

open access: yes, 1986
The precursor for a Lemna light-harvesting chlorophyll a/b protein (pLHCP) has been synthesized in vitro from a single member of the nuclear LHCP multigene family. We report the sequence of this gene.

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of
