Abstract

Agricultural production continues to be constrained by a number of biotic and abiotic factors that can reduce crop yield quantity and quality. Potassium (K) is an essential nutrient that affects most of the biochemical and physiological processes that influence plant growth and metabolism. It also contributes to the survival of plants exposed to various biotic and abiotic stresses. The following review focuses on the emerging role of K in defending against a number of biotic and abiotic stresses, including diseases, pests, drought, salinity, cold and frost and waterlogging. The availability of K and its effects on plant growth, anatomy, morphology and plant metabolism are discussed. The physiological and molecular mechanisms of K function in plant stress resistance are reviewed. This article also evaluates the potential for improving plant stress resistance by modifying K fertilizer inputs and highlights the future needs for research about the role of K in agriculture.

Differential tolerance to combined salinity and O2 deficiency in the halophytic grasses Puccinellia ciliata and Thinopyrum ponticum: The importance of K + retention in roots

Puccinellia ciliata shows greater tolerance to salinity and hypoxia due to increased root production, regulation of shoot K+/Na+, and maintaining negative membrane potential in root cells.

Hypoxia reduces germination and nutrient uptake in barley seedlings, with salinity and hypoxia together inhibiting germination and early growth.

Difference in sodium spatial distribution in the shoot of two canola cultivars under saline stress.

Canola cultivar NYY 1 has higher resistance to salt stress due to its ability to confine sodium in the apoplast, avoiding leaf salt toxicity.

Waterlogging stress in plants: A review

Plants adapt to waterlogging stress by switching from aerobic respiration to anaerobic fermentation, reducing stomata conductance, and exhibiting morphological changes to cope with oxygen deficiency and oxidative damage.
