“…Unfortunately, studies on antioxidant capacity and antioxidant-related traits in tomato are limited and these have focused on vitamin C, vitamin E, carotenoids and total phenolic acids but not glutathione or individual phenolic acids. The existing studies on glutathione evaluated changes in glutathione content under stress conditions, especially salinity stress [49][50][51][52][53].…”

“…Shi et al [25] suggested that PAs could activate multiple pathways that enhance bermudagrass adaption to salinity, which may be applicable for genetically engineering crop plants to improve stress tolerance. In tomato, exogenous Spd application combined with salinity-alkalinity stress decreased the superoxide anion (O 2 -) generation rate and MDA content, as well as increased ascorbate-glutathione cycle components, which resulted in alleviation damage produced by these stresses [73]. In cucumber seedlings, a positive effect of exogenous Spd on photosynthesis associated to improved tolerance to salinity has also been observed [74].…”

In recent years, climate change has altered many ecosystems due to a combination of frequent droughts, irregular precipitation, increasingly salinized areas and high temperatures. These environmental changes have also caused a decline in crop yield worldwide. Therefore, there is an urgent need to fully understand the plant responses to abiotic stress and to apply the acquired knowledge to improve stress tolerance in crop plants. The accumulation of polyamines (PAs) in response to many abiotic stresses is one of the most remarkable plant metabolic responses. In this review, we provide an update about the most significant achievements improving plant tolerance to drought, salinity, low and high temperature stresses by exogenous application of PAs or genetic manipulation of endogenous PA levels. We also provide some clues about possible mechanisms underlying PA functions, as well as known cross-talks with other stress signaling pathways. Finally, we discuss about the possible use of PAs for seed priming to induce abiotic stress tolerance in agricultural valuable crop plants.

“…Additionally, Spd application reduced the superoxide production and lipid peroxidation and improved the ascorbate-glutathione cycle components, resulting in the reduction of damage in tomato plants with salinity-alkalinity exposure ( Zhang et al., 2016b ). In cucumber, a beneficial impact of Spd application on photosynthesis was associated with higher tolerance under salt stress ( Sang et al., 2016 ); moreover, exogenously supplied Spd also enhanced salinity tolerance in zoysia grass through improving PA metabolism by increasing arginine decarboxylase (ADC), S-adenosylmethionine decarboxylase (SAMDC), and diamine oxidase (DAO) activities ( Li et al., 2017 ).…”

In recent years, extreme environmental cues such as abiotic stresses, including frequent droughts with irregular precipitation, salinity, metal contamination, and temperature fluctuations, have been escalating the damage to plants’ optimal productivity worldwide. Therefore, yield maintenance under extreme events needs improvement in multiple mechanisms that can minimize the influence of abiotic stresses. Polyamines (PAs) are pivotally necessary for a defensive purpose under adverse abiotic conditions, but their molecular interplay in this remains speculative. The PAs’ accretion is one of the most notable metabolic responses of plants under stress challenges. Recent studies reported the beneficial roles of PAs in plant development, including metabolic and physiological processes, unveiling their potential for inducing tolerance against adverse conditions. This review presents an overview of research about the most illustrious and remarkable achievements in strengthening plant tolerance to drought, salt, and temperature stresses by the exogenous application of PAs. The knowledge of underlying processes associated with stress tolerance and PA signaling pathways was also summarized, focusing on up-to-date evidence regarding the metabolic and physiological role of PAs with exogenous applications that protect plants under unfavorable climatic conditions. Conclusively, the literature proposes that PAs impart an imperative role in abiotic stress tolerance in plants. This implies potentially important feedback on PAs and plants’ stress tolerance under unfavorable cues.
