Importance of Radioactive Labelling to Elucidate Inositol Polyphosphate Signalling [PDF]

, 2017
Inositol polyphosphates, in their water-soluble or lipid-bound forms, represent a large and multifaceted family of signalling molecules. Some inositol polyphosphates are well recognised as defining important signal transduction pathways, as in the case ...

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,

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, EarlyView.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

A Crh-specific function in carbon catabolite repression in Bacillus subtilis [PDF]

, 2003
Carbon catabolite repression in Bacillus subtilis is mediated by phosphorylation of the phosphoenolpyruvate: carbohydrate phosphotransferase system intermediate HPr at a serine residue catalyzed by HPr kinase.

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

Journal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

Fungal Kinases With a Sweet Tooth: Pleiotropic Roles of Their Phosphorylated Inositol Sugar Products in the Pathogenicity of Cryptococcus neoformans Present Novel Drug Targeting Opportunities

Frontiers in Cellular and Infection Microbiology, 2019
Invasive fungal pathogens cause more than 300 million serious human infections and 1.6 million deaths per year. A clearer understanding of the mechanisms by which these fungi cause disease is needed to identify novel targets for urgently needed therapies.

Consequences of simulated microgravity in neural stem cells: biological effects and metabolic response. [PDF]

, 2015
Objective: Microgravity was often shown to cause cell damage and impair cell cycle in a variety of biological systems. Since the effects on the neural system were poorly investigated, we aimed to gain insight into how biological processes such as cell ...

SlMED25‐SlPHR3‐SlSPX2 module fine‐tunes SlPHR3‐mediated transcriptional activation of phosphate starvation response in tomato

Journal of Integrative Plant Biology, EarlyView.
The Mediator subunit SlMED25 and the co‐repressor SlSPX2 competitively bind the N‐terminal domain of the phosphate starvation response transcription factor SlPHR3 in tomato to form a sensitive molecular switch, which dynamically modulates phosphate starvation responses and maintains phosphate homeostasis, offering valuable targets for breeding low ...

Regulation of Inositol Metabolism Is Fine-tuned by Inositol Pyrophosphates in Saccharomyces cerevisiae* [PDF]

Journal of Biological Chemistry, 2013
Although inositol pyrophosphates have diverse roles in phosphate signaling and other important cellular processes, little is known about their functions in the biosynthesis of inositol and phospholipids. Here, we show that KCS1, which encodes an inositol pyrophosphate kinase, is a regulator of inositol metabolism.
