Potential of golden potatoes to improve vitamin A and vitamin E status in developing countries. [PDF]

PLoS ONE, 2017
Potato (Solanum tuberosum L.) is the third most widely consumed plant food by humans. Its tubers are rich in starch and vitamin C, but have low or null levels of essential nutrients such as provitamin A and vitamin E.

Phytoene Desaturase from Oryza sativa: Oligomeric Assembly, Membrane Association and Preliminary 3D-Analysis. [PDF]

PLoS ONE, 2015
Recombinant phytoene desaturase (PDS-His6) from rice was purified to near-homogeneity and shown to be enzymatically active in a biphasic, liposome-based assay system. The protein contains FAD as the sole protein-bound redox-cofactor.

Plant-type phytoene desaturase: Functional evaluation of structural implications. [PDF]

PLoS ONE, 2017
Phytoene desaturase (PDS) is an essential plant carotenoid biosynthetic enzyme and a prominent target of certain inhibitors, such as norflurazon, acting as bleaching herbicides.

Phytoene and Phytoene-Rich Microalgae Extracts Extend Lifespan in C. elegans and Protect against Amyloid-β Toxicity in an Alzheimer’s Disease Model

Antioxidants
Phytoene is a colourless carotenoid widely available from dietary sources and a precursor for the synthesis of other carotenoids. Although present at high concentrations across different tissues, phytoene is largely viewed as not having physiological ...

The Carrot Phytoene Synthase 2 (DcPSY2) Promotes Salt Stress Tolerance through a Positive Regulation of Abscisic Acid and Abiotic-Related Genes in Nicotiana tabacum

Plants, 2023
Background: Carotenoids, which are secondary metabolites derived from isoprenoids, play a crucial role in photo-protection and photosynthesis, and act as precursors for abscisic acid, a hormone that plays a significant role in plant abiotic stress ...

From Temperature Fluctuations to Precise Control: Biochemical Techniques Integrated Digital‐Intelligent Technology for Vegetable Preservation

Future Postharvest and Food, EarlyView.
The physiological effects and molecular responses of postharvest vegetables to temperature fluctuations, and multi‐technology integration strategies for maintaining postharvest vegetable quality. ABSTRACT Vegetables are indispensable agricultural products in the human diet. With the continuous growth of vegetable production and consumption, postharvest

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.

The Bacterial Phytoene Desaturase-Encoding Gene (CRTI) is an Efficient Selectable Marker for the Genetic Transformation of Eukaryotic Microalgae

Metabolites, 2019
Genetic manipulation shows great promise to further boost the productivity of microalgae-based compounds. However, selection of microalgal transformants depends mainly on the use of antibiotics, which have raised concerns about their potential impacts on

Optimized TadA‐derived base editors efficiently manipulate mRNA splicing by A‐to‐G and C‐to‐K editing in potato

Journal of Integrative Plant Biology, EarlyView.
Two optimized TadA‐derived base editors efficiently generate diverse splicing variants by targeting specific splice sites in potato. ABSTRACT Pre‐messenger RNA (pre‐mRNA) splicing is a critical mechanism for post‐transcriptional regulation in plants. Through alternative splicing, plants produce diverse transcriptomes and proteomes that finely regulate ...
