Role of Potassium in Plants

Beschreibung Autorinnen & Autoren

Potassium (K⁺) is an essential mineral macronutrient abundantly present in the cytosol which, unlike other macronutrients, is not metabolized and does not integrate into macromolecules. Compared to animal cells, K⁺ is more abundantly present in plant cells.

Overall performance of the plant, and operation of metabolic machinery depends upon intracellular K⁺ homeostasis (K⁺ uptake and efflux) via K⁺ channels and transporters acting as mediators of cellular responses during plant development. Unlike animals, plants lack sodium/K⁺ exchangers; plant cells have developed unique transport systems for K⁺ accumulation and release. In Arabidopsis thaliana, 71 K⁺ channels and transporters have been identified and categorized into six families.

Plant adaptive responses to several abiotic and biotic stresses are mediated by regulation of intracellular K⁺ homeostasis. In this report, we highlight the role of K⁺ in abiotic and biotic stresses, features of channels and transporters responsible for its homeostasis along with its evolutionary relationship, perception and sensing mechanisms, and K⁺ deficiency triggering different signaling cascades.

Overall, this book covers the role of K⁺in plants would be significantly helpful to research, academic community as well as students to understand the one of the major attributes of plant biology.
