Quantitation of Cytochromes b559, b6, and f, and the Core Component of Photosystem I P700 in Cyanobacterial Cells

Bio-Protocol, 2016
Cytochrome (Cyt) b559, an important and essential core component of photosystem II in the photosynthetic electron transport system, is a heme-bridged heterodimer protein composed of an alpha subunit (PsbE) and a beta subunit (PsbE), and its reduced form ...

The Vesicle-inducing Protein 1 from Synechocystis sp. PCC 6803 Organizes into Diverse Higher-Ordered Ring Structures [PDF]

, 2009
The vesicle-inducing protein in plastids 1 (Vipp1) was found to be involved in thylakoid membrane formation in chloroplasts and cyanobacteria. In contrast to chloroplasts, it has been suggested that in cyanobacteria the protein is only tightly associated

Assessing plant water status: Part 1 – Classical methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

Dynamic reorganization of photosynthetic supercomplexes during environmental acclimation

Frontiers in Plant Science, 2013
Plants and algae have acquired the ability to acclimate to ever-changing environments in order to survive. During photosynthesis, light energy is converted by several membrane protein supercomplexes into electrochemical energy, which is eventually used ...

The protein matrix of plastocyanin supports long-distance charge transport with photosystem I and the copper ion regulates its spatial span and conductance

, 2023
Charge exchange is the fundamental process that sustains cellular respiration and photosynthesis by shuttling electrons in a cascade of electron transfer (ET) steps between redox cofactors.

Apple scar skin viroid causes dapple and scar skin apple diseases by disrupting phenylpropanoid‐mediated metabolic pathways

New Plant Protection, EarlyView.
Dapple apple and scar skin apple diseases are closely associated with suppression of anthocyanin biosynthesis and enhancement of suberin biosynthesis. Apple scar skin viroid (ASSVd) infection represses anthocyanin biosynthesis in apple callus. Abstract Apple scar skin viroid (ASSVd) causes dapple and scar skin apple diseases, posing serious threats to ...

One-step isolation and biochemical characterization of a highlyactive plant PSII monomeric core

, 2011
We describe a one-step detergent solubilization protocol for isolating a highly active form of Photosystem II (PSII) from Pisum sativum L. Detailed characterization of the preparation showed that the complex was a monomer having no light harvesting ...

Integrating tunable LED‐induced plant responses with novel solar cell technologies for energy‐efficient agrivoltaic systems

PLANTS, PEOPLE, PLANET, EarlyView.
The increasing demand for sustainable food production requires innovative solutions that balance productivity, resource efficiency, and environmental impact. Vertical Farming Systems (VFSs) offer a promising approach; however, their high energy consumption remains challenging.

Role of Protein-Water Interface in the Stacking Interactions of Granum Thylakoid Membranes—As Revealed by the Effects of Hofmeister Salts

Frontiers in Plant Science, 2020
The thylakoid membranes of vascular plants are differentiated into stacked granum and unstacked stroma regions. The formation of grana is triggered by the macrodomain formation of photosystem II and light-harvesting complex II (PSII-LHCII) and thus their

Protein–cofactor interactions in bioenergetic complexes: The role of the A1A and A1B phylloquinones in Photosystem I

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2009
This review focuses on phylloquinone as an indispensable link between light-induced charge separation and subsequent charge stabilization in Photosystem I (PS I). Here, the role of the polypeptide in conferring the necessary kinetic and thermodynamic properties to phylloquinone so as to specify its functional role in PS I electron transfer is discussed.
