Regulation of potassium transport in plants under hostile conditions: implications for abiotic and biotic stress tolerance
Open accessAbstract
Intracellular potassium homeostasis is a prerequisite for the optimal operation of plant metabolic machinery and plant's overall performance. It is controlled by K+ uptake, efflux and intracellular and long‐distance relocation, mediated by a large number of K+‐selective and non‐selective channels and transporters located at both plasma and vacuolar membranes. All abiotic and biotic stresses result in a significant disturbance to intracellular potassium homeostasis. In this work, we discuss molecular mechanisms and messengers mediating potassium transport and homeostasis focusing on four major environmental stresses: salinity, drought, flooding and biotic factors. We argue that cytosolic K+ content may be considered as one of the ‘master switches’ enabling plant transition from the normal metabolism to ‘hibernated state’ during first hours after the stress exposure and then to a recovery phase. We show that all these stresses trigger substantial disturbance to K+ homeostasis and provoke a feedback control on K+ channels and transporters expression and post‐translational regulation of their activity, optimizing K+ absorption and usage, and, at the extreme end, assisting the programmed cell death. We discuss specific modes of regulation of the activity of K+ channels and transporters by membrane voltage, intracellular Ca 2+, reactive oxygen species, polyamines, phytohormones and gasotransmitters, and link this regulation with plant‐adaptive responses to hostile environments.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
