Chloroplast Movement Imaging Under Different Light Regimes With a Hyperspectral Camera [PDF]

Bio-Protocol
Plants move chloroplasts in response to light, changing the optical properties of leaves. Low irradiance induces chloroplast accumulation, while high irradiance triggers chloroplast avoidance.

Light-driven processes: key players of the functional biodiversity in microalgae

Comptes Rendus Biologies, 2022
Microalgae are prominent aquatic organisms, responsible for about half of the photosynthetic activity on Earth. Over the past two decades, breakthroughs in genomics and ecosystem biology, as well as the development of genetic resources in model species ...

The fine-tuning of NPQ in diatoms relies on the regulation of both xanthophyll cycle enzymes

Scientific Reports, 2021
Diatoms possess an efficient mechanism to dissipate photons as heat in conditions of excess light, which is visualized as the Non-Photochemical Quenching of chlorophyll a fluorescence (NPQ).

Imaging of the Entry Pathway of a Cell-Penetrating Peptide–DNA Complex From the Extracellular Space to Chloroplast Nucleoids Across Multiple Membranes in Arabidopsis Leaves

Frontiers in Plant Science, 2021
Each plant cell has hundreds of copies of the chloroplast genome and chloroplast transgenes do not undergo silencing. Therefore, chloroplast transformation has many powerful potential agricultural and industrial applications.

Decoding the Virtual 2D Map of the Chloroplast Proteomes

Biological Procedures Online, 2022
Background The chloroplast is a semi-autonomous organelle having its own genome and corresponding proteome. Although chloroplast genomes have been reported, no reports exist on their corresponding proteomes.

Osj10gBTF3-Mediated Import of Chloroplast Protein Is Essential for Pollen Development in Rice

Frontiers in Plant Science, 2021
Chloroplasts are crucial organelles for the generation of fatty acids and starch required for plant development. Nascent polypeptide-associated complex (NAC) proteins have been implicated in development as transcription factors.

Anticodon table of the chloroplast genome and identification of putative quadruplet anticodons in chloroplast tRNAs

Scientific Reports, 2023
The chloroplast genome of 5959 species was analyzed to construct the anticodon table of the chloroplast genome. Analysis of the chloroplast transfer ribonucleic acid (tRNA) revealed the presence of a putative quadruplet anticodon containing tRNAs in the ...

Chloroplast proteostasis: A story of birth, life, and death

Plant Communications, 2023
Protein homeostasis (proteostasis) is a dynamic balance of protein synthesis and degradation. Because of the endosymbiotic origin of chloroplasts and the massive transfer of their genetic information to the nucleus of the host cell, many protein ...

A Sec14 domain protein is required for photoautotrophic growth and chloroplast vesicle formation in Arabidopsis thaliana. [PDF]

, 2020
In eukaryotic photosynthetic organisms, the conversion of solar into chemical energy occurs in thylakoid membranes in the chloroplast. How thylakoid membranes are formed and maintained is poorly understood.
