Anthocyanin Biosynthesis and Degradation Mechanisms in Solanaceous Vegetables: A Review

Frontiers in Chemistry, 2018
Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom. In plants, anthocyanins play a role not only in reproduction, by attracting pollinators and seed dispersers, but also in protection against various ...

The regulation of ethylene biosynthesis: a complex multilevel control circuitry

New Phytologist, 2020
Summary The gaseous plant hormone ethylene is produced by a fairly simple two‐step biosynthesis route. Despite this pathway’s simplicity, recent molecular and genetic studies have revealed that the regulation of ethylene biosynthesis is far more complex ...

Effect of very low nicotine content cigarettes on smoking behavior in Chinese smokers with genotype-stratified nicotine metabolism rates

Frontiers in Psychiatry
BackgroundSmoking is a major public health issue worldwide, particularly in China where it is linked to serious diseases like lung cancer and cardiovascular disease. The genetic basis of nicotine metabolism, which varies significantly between Chinese and

Regulatory Mechanisms of Anthocyanin Biosynthesis in Apple and Pear

International Journal of Molecular Sciences, 2021
Anthocyanins contribute to the quality and flavour of fruits. They are produced through the phenylpropanoid pathway, which is regulated by specific key genes that have been identified in many species.

A new type of DNA phosphorothioation-based antiviral system in archaea

Nature Communications, 2019
The prokaryote defence system Dnd relies on phosphorothioation (PT) of DNA backbone to distinguish between self and non-self DNA. Here, Xiong et al. describe a previously uncharacterized PT-based antiviral system that is independent of the canonical Dnd ...

Puromycin A, B and C, cryptic nucleosides identified from Streptomyces alboniger NRRL B-1832 by PPtase-based activation

Synthetic and Systems Biotechnology, 2018
Natural product discovery is pivot for drug development, however, this endeavor is often challenged by the wide inactivation or silence of natural products biosynthetic pathways.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
