Role of Phosphorus in Imparting Abiotic Stress Tolerance to Plants

Phosphorus Plays Key Roles in Regulating Plants’ Physiological Responses to Abiotic Stresses

“…P fertilization increases enzymatic activities including SOD, MDA, POD, CAT and organic osmolyte accumulation (e.g., proline) [14,138,140,157]. Additionally, proteins and metabolites related to drought tolerance are increased by P fertilization [12]. In addition to regulating phosphorus uptake and utilization, plants also have several mechanisms to cope with abiotic stress by modulating their phosphorus metabolism [12].…”

“…Additionally, proteins and metabolites related to drought tolerance are increased by P fertilization [12]. In addition to regulating phosphorus uptake and utilization, plants also have several mechanisms to cope with abiotic stress by modulating their phosphorus metabolism [12]. For example, when subjected to drought stress, plants may upregulate the expression of genes responsible for the synthesis and accumulation of compatible solutes, such as proline and glycine betaine, which help to protect the plant from the effects of water stress.…”

“…Plants possess the capability to sense and respond to variations in phosphorus availability through specific signaling pathways, root architecture modulation and stomatal morphology adjustments [10,11]. Moreover, by modulating their phosphorus metabolism, plants can tolerate diverse abiotic stresses including heat, drought, salinity and heavy metal toxicity, where stomatal responses are particularly relevant [12][13][14][15]. Understanding the mechanisms by which plants sense and respond to phosphorus availability is crucial for developing strategies that enhance crop productivity and stress tolerance.…”
