Functional Characterization of the First Bona Fide Phytoene Synthase in Red Algae from Pyropia yezoensis

Marine Drugs
The formation of phytoene by condensing two geranylgeranyl diphosphate molecules catalyzed by phytoene synthase (PSY) is the first committed and rate-limiting step in carotenoid biosynthesis, which has been extensively investigated in bacteria, land ...

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Carotenoid Biosynthesis: Genome-Wide Profiling, Pathway Identification in Rhodotorula glutinis X-20, and High-Level Production

Frontiers in Nutrition, 2022
Rhodotorula glutinis, as a member of the family Sporidiobolaceae, is of great value in the field of biotechnology. However, the evolutionary relationship of R. glutinis X-20 with Rhodosporidiobolus, Sporobolomyces, and Rhodotorula are not well understood,

Pb2+ tolerance by Frankia sp. strain EAN1pec involves surface-binding [PDF]

, 2017
Several Frankia strains have been shown to be lead-resistant. The mechanism of lead resistance was investigated for Frankia sp. strain EAN1pec. Analysis of the cultures by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX ...

Insights from controlled, comparative experiments highlight the limitations of using BSMV and FoMV for virus‐enabled reverse genetics in rice

Annals of Applied Biology, EarlyView.
Virus‐enabled reverse genetics (VERG) enables transient gene expression modulation in plants but its efficacy varies across species. We evaluated the efficacy of barley stripe mosaic virus (BSMV) and foxtail mosaic virus (FoMV) for virus‐induced gene silencing (VIGS) and virus‐mediated overexpression (VOX) in rice (Oryza sativa).

Antioxidative and chaperone‐like activities of a bacterioruberin‐rich extract: An innovative approach to protect the skin proteome

International Journal of Cosmetic Science, EarlyView.
The bacteriorubin‐rich extract of Arthrobacter agilis has high antioxidative properties, protecting proteins against oxidative stress and preventing their carbonylation. It also protects proteins against saline and heat stresses, suggesting a dual mode of action including antioxidant and chaperone‐like activities.

The regulation of carotenoid formation in tomato fruit [PDF]

, 2017
Carotenoid biosynthesis in plants includes a complex series of desaturation/isomerisation reactions, catalysed by four independent enzymes. In bacteria and fungi one desaturase/isomerase enzyme completes the same series of reactions. In the present study,

Silencing of the phytoene desaturase (PDS) gene affects the expression of fruit-ripening genes in tomatoes

Plant Methods, 2019
Past research has shown that virus-induced phytoene desaturase (PDS) gene silencing via agroinjection in the attached and detached fruit of tomato plants results in a pale-yellow fruit phenotype.
