Potassium Deficiency and Hormone Signalling in Plants

Plant, Cell &Environment, Volume 49, Issue 6, Page 2935-2951, June 2026.
ABSTRACT Potassium (K or K⁺) is a vital macronutrient that influences numerous physiological processes related to plant physiology and development. Recently, there is a growing focus on enhancing K+‐use efficiency (KUE) to ensure optimal plant growth, especially in K+ deficient soils.

Multiple PIP2 binding sites in Kir2.1 inwardly rectifying potassium channels

, 2001
Inwardly rectifying potassium channels require binding of phosphatidylinositol-4,5-bisphosphate (PIP2) for channel activity. Three independent sites (aa 175–206, aa 207–246, aa 324–365) were located in the C-terminal domain of Kir2.1 channels by assaying

Potassium silicate improves cellular sodium homeostasis in wheat (Triticum aestivum L.) cultivars differing in salt resistance

Plant Biology, Volume 28, Issue 4, Page 1043-1051, June 2026.
Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis. Abstract Salinity causes negative impacts on crops. We investigated the effect of potassium silicate (K2SiO3) on the cytosolic uptake of sodium, [Na+]cyt, in mesophyll protoplasts of wheat cultivars differing ...

Emerging roles for G protein-gated inwardly rectifying potassium (GIRK) channels in health and disease

, 2010
G protein-gated inwardly rectifying potassium (GIRK) channels hyperpolarize neurons in response to activation of many different G protein-coupled receptors and thus control the excitability of neurons through GIRK-mediated self-inhibition, slow synaptic ...

Erg currents support electrical bursting in murine anterior pituitary corticotrophs

The Journal of Physiology, Volume 604, Issue 12, Page 4834-4850, 15 June 2026.
Abstract figure legend Anterior pituitary corticotrophs are a central component of the hypothalamic‐pituitary‐adrenal (HPA) axis that controls the release of glucocorticoids from the adrenal gland in response to stress. The hypothalamic secretagogue corticotrophin releasing hormone (CRH) promotes electrical bursting of mouse anterior pituitary ...

Ion activities and potassium uptake mechanisms of glial cells in guinea-pig olfactory cortex slices. [PDF]

, 1987
1. Double-barrelled ion-sensitive micro-electrodes were used to measure changes in the intracellular activities of K+, Na+ and Cl- (aiK, aiNa, aiCl) in glial cells of slices from guinea-pig olfactory cortex during repetitive stimulation of the lateral ...

Potentiation of Opioid-Induced Analgesia by L-Type Calcium Channel Blockers: Need for Clinical Trial in Cancer Pain

Indian Journal of Anaesthesia, 2008
Previous reports indicate that the analgesic effect of opioids is due to both closure of specific voltage-gated calcium channels (N- and P/Q-types) and opening of G protein-coupled inwardly rectifying potassium channels (GIRKs) in neurons concerned with ...

Structural determinants for interaction of inwardly rectifying potassium channel proteins with phosphatidylinositol 4,5-Bisphosphate

, 2002
This study concerns the investigations of direct interaction of the various proteins forming inwardly rectifying potassium channels in mammalian cells (Kir proteins) with phosphoinositol phospholipids, especially phospahtidylinositol-4,5 bisphosphate (PI(

Development of Molecular Tools for the Investigation of G protein-gated Inwardly Rectifying Potassium (GIRK) Channels

, 2017
G protein-gated inwardly rectifying potassium (GIRK) ion channels are part of a larger family of inwardly rectifying potassium channels (Kirs) that regulate diverse biological processes.
