Mutant-based model of two independent pathways for carotenoid-mediated chloroplast biogenesis in Arabidopsis embryos [PDF]

, 2019
Chloroplasts are essential for autonomous plant growth, and their biogenesis is a complex process requiring both plastid and nuclear genome. One of the essential factors required for chloroplast biogenesis are carotenoids.

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

Integrative Zoology, EarlyView.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Plastid intramembrane proteolysis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015
Progress in the field of regulated intramembrane proteolysis (RIP) in recent years has not surpassed plant biology. Nevertheless, reports on RIP in plants, and especially in chloroplasts, are still scarce. Of the four different families of intramembrane proteases, only two have been linked to chloroplasts so far, rhomboids and site-2 proteases (S2Ps ...

A Practical Comparison of Short‐ and Long‐Read Metabarcoding Sequencing: Challenges and Solutions for Plastid Read Removal and Microbial Community Exploration of Seaweed Samples

Molecular Ecology Resources, EarlyView.
ABSTRACT Short‐read metabarcoding analysis is the gold standard for accessing partial 16S and ITS genes with high read quality. With the advent of long‐read sequencing, the amplification of full‐length target genes is possible, but with low read accuracy.

Structural analyses of ABA transporters give new impetus to the study of ABA regulation

Annals of Applied Biology, EarlyView.
Abscisic acid (ABA) regulates key physiological processes and coordinates abiotic stress responses. In the six decades since it was first described, a huge amount of work has been conducted on ABA synthesis, breakdown and signalling mechanisms. Recently, attention has been turned to the role of ABA transporters, and the elucidation in exquisite detail ...

Insights into a dinoflagellate genome through expressed sequence tag analysis [PDF]

, 2005
BACKGROUND: Dinoflagellates are important marine primary producers and grazers and cause toxic "red tides". These taxa are characterized by many unique features such as immense genomes, the absence of nucleosomes, and photosynthetic organelles (plastids)

d‐amino acids: new functional insights

The FEBS Journal, EarlyView.
This review explores recent advances in understanding d‐amino acids (d‐AAs) and their pivotal roles across organisms, from plants to humans. d‐AAs have been implicated in key physiological processes, including cancer, inflammation, immune regulation, kidney disease, diabetes, and nervous system function.

NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches. [PDF]

, 2019
Phytochromes initiate chloroplast biogenesis by activating genes encoding the photosynthetic apparatus, including photosynthesis-associated plastid-encoded genes (PhAPGs).

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis

The FEBS Journal, EarlyView.
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

The toxic effects of meta‐tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria

The FEBS Journal, EarlyView.
This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...
