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.

Chloroplast Division [PDF]

Traffic, 2007
Chloroplasts are descendants of cyanobacteria and divide by binary fission. Several components of the division apparatus have been identified in the past several years and we are beginning to appreciate the plastid division process at a mechanistic level.

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 ...

Retrograde signaling in plants: A critical review focusing on the GUN pathway and beyond

Plant Communications, 2023
Plastids communicate their developmental and physiological status to the nucleus via retrograde signaling, allowing nuclear gene expression to be adjusted appropriately.

Updated Progress on Group II Intron Splicing Factors in Plant Chloroplasts

Current Issues in Molecular Biology, 2022
Group II introns are large catalytic RNAs (ribozymes) in the bacteria and organelle genomes of several lower eukaryotes. Many critical photosynthesis-related genes in the plant chloroplast genome also contain group II introns, and their splicing is ...

Chloroplast Glutathione Reductase [PDF]

Plant Physiology, 1977
Glutathione reductase (EC 1.6.4.2) activity is present in spinach (Spinacia oleracea L.) chloroplasts. The pH dependence and substrate concentration for half-maximal rate are reported and a possible role in chloroplasts is proposed.
