Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

Biotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.

Structural and functional characterisation of Photosystem II from two His-tagged transplastomic strains of Nicotiana tabacum [PDF]

, 2009
Photosystem II (PSII) is a polypeptide-cofactor complex organised as a homodimeric multisubunit protein embedded in the thylakoid membrane. PSII monomers are heterooligomers related to each other by a pseudo-twofold axis perpendicular to the membrane ...

A Naphthalene Monoimide Meisenheimer Complex as Strong Organic Hydride Donor for Metal‐Free CO2 Reduction

Chemistry – A European Journal, EarlyView.
A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

The effect of nicosulfuron and bentazon on photosynthetic performance of common cocklebur (Xanthium strumarium L.)

Environmental and Sustainability Indicators, 2020
In order to evaluate the effects of bentazon and nicosulfuron on the photosynthetic apparatus of X. strumarium in greenhouse condition, chlorophyll a fluorescence (ChlF) method was studied at 1, 2, 3, and 4 days after herbicide treatment (DAHT). Bentazon

A Low‐Oxidation‐State Mechanism for O─O Bond Formation in Photosystem II via Oxo–Hydroxyl Radical Coupling

Chemistry – A European Journal, EarlyView.
An oxo–hydroxyl radical coupling mechanism is identified for O─O bond formation in Photosystem II within the low‐oxidation‐state paradigm. Ca‐bound W3 forms Ox in the S4 state and subsequently couples with O5. The resulting hydroperoxide intermediate provides a mechanistic explanation for the poor resolution of Ox in XFEL structures.
