Computational analysis and expression profiling of potassium transport-related gene families in mango (Mangifera indica) indicate their role in stress response and fruit development

Frontiers in Plant Science, 2023
Mango (Mangifera indica) fruit is known for its taste, health benefits, and drought tolerance. Potassium (K+) is one of the most abundant ions in a plant cell.

Adaptation to potassium

Kidney International, 1977
In vertebrates, the development of complex and efficient mechanisms for avoiding potassium intoxication might be predicted from a simple consideration of their chemical anatomy. The proper function of excitable membranes depends on a low concentration of potassium outside of the cell.

When Is a Potassium Channel Not a Potassium Channel?

Function, 2022
AbstractEver since they were first observed in Purkinje fibers of the heart, funny channels have had close connections to potassium channels. Indeed, funny channels were initially thought to produce a potassium current in the heart called IK2. However, funny channels are completely unlike potassium channels in ways that make their contributions to the ...

Studies on the interaction of growth regulators with potassium ions in some physiological processes in bean (Phaseolus vulgaris L.). III The effect of growth regulators on growth, chlorophyll level and transpiration depending on potassium concentration

Acta Societatis Botanicorum Poloniae, 2014
Leaf growth and chlorophyll level in GA3-treated bean, and leaf growth and transpiration intensity in ABA-treated bean plants were studied at two potassium concentrations in the medium (1 and 3 mM KNO3).

Element content and distribution has limited, tolerance metric dependent, impact on salinity tolerance in cultivated sunflower (Helianthus annuus)

Plant Direct, 2020
Disruption of ion homeostasis is a major component of salinity stress's effect on crop yield. In cultivated sunflower prior work revealed a negative relationship between vigor and salinity tolerance.

Evidence for the formation of a Mott state in potassium-intercalated pentacene [PDF]

Phys. Rev. B. 79, 125116 (2009), 2008
We investigate electronic transport through pentacene thin-films intercalated with potassium. From temperature-dependent conductivity measurements we find that potassium-intercalated pentacene shows metallic behavior in a broad range of potassium concentrations.
