Two inositol hexakisphosphate kinases drive inositol pyrophosphate synthesis in plants [PDF]

open access: yesThe Plant Journal, 2014
SummaryInositol pyrophosphates are unique cellular signaling molecules with recently discovered roles in energy sensing and metabolism. Studies in eukaryotes have revealed that these compounds have a rapid turnover, and thus only small amounts accumulate.

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

open access: yesJournal 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 ...

Nucleolar Architecture Is Modulated by a Small Molecule, the Inositol Pyrophosphate 5-InsP7

open access: yesBiomolecules, 2023
Inositol pyrophosphates (PP-InsPs); are a functionally diverse family of eukaryotic molecules that deploy a highly-specialized array of phosphate groups as a combinatorial cell-signaling code.

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

open access: yesJournal 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 ...

Wheat inositol pyrophosphate kinase TaVIH2-3B modulates cell-wall composition and drought tolerance in Arabidopsis

open access: yesBMC Biology, 2021
Background Inositol pyrophosphates (PP-InsPs) are high-energy derivatives of inositol, involved in different signalling and regulatory responses of eukaryotic cells.

Transcriptome assemblies for two drug‐type cannabis chemotypes by long‐read RNA sequencing

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Cannabis sativa has undergone over 10,000 years of domestication, resulting in extensive genetic and phenotypic diversity among cultivated chemotypes. Increased medical and recreational use of specialized metabolites accumulating in cannabis glandular trichomes—primarily the cannabinoids ∆9‐tetrahydrocannabinol (THC) and cannabidiol (CBD)—has ...

Fluorination Influences the Bioisostery of Myo‐Inositol Pyrophosphate Analogs

open access: yesChemistry – A European Journal, 2023
AbstractInositol pyrophosphates (PP−IPs) are densely phosphorylated messenger molecules involved in numerous biological processes. PP−IPs contain one or two pyrophosphate group(s) attached to a phosphorylated myo‐inositol ring. 5PP−IP5 is the most abundant PP−IP in human cells. To investigate the function and regulation by PP−IPs in biological contexts,

Inositol Pyrophosphate Metabolism Regulates Presynaptic Vesicle Cycling at Central Synapses

open access: yesiScience, 2020
Summary: The coordination of synaptic vesicle exocytosis and endocytosis supports neurotransmitter release from presynaptic terminals. Although inositol pyrophosphates, such as 5-diphosphoinositol pentakisphosphate (5-IP7), are versatile signaling ...

Inositol pyrophosphates modulate hydrogen peroxide signalling

open access: yesBiochemical Journal, 2009
Inositol pyrophosphates are involved in a variety of cellular functions, but the specific pathways and/or downstream targets remain poorly characterized. In the present study we use Saccharomyces cerevisiae mutants to examine the potential roles of inositol pyrophosphates in responding to cell damage caused by ROS (reactive oxygen species).

Inactivation Strategies of Clostridium perfringens in Foods: Current Challenges and Emerging Interventions

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Clostridium perfringens forms heat‐resistant spores that complicate food safety. Physical methods (thermal processing, HPP, vacuum cooling, ozone treatments) and chemical interventions (natural antimicrobials, phosphates, nitrate/nitrite, organic acids) reduce vegetative cells and spores, though spore resistance remains a major challenge in food and ...
