“…Secondary metabolites mediate stress signals for the elicitation of a better stress response [77]. Polyamines conjugate with phenols including ferulic acid and caffeic acid, resulting in their improved stability and translocation [78]. The increased accumulation of secondary metabolites results from the up-regulation of the activities of enzymes involved in their biosynthesis [9,63,75].…”

Pot experiments were conducted to investigate the probable beneficial role of the individual as well as combined application of kinetin (50 μM Kn) and spermidine (200 μM Spd) on Vigna angularis under cadmium (Cd) stress. Cd treatment reduced growth by declining the content of chlorophylls and carotenoids, photosynthesis, and gas exchange parameters. Exogenously, Kn and Spd application enhanced the photosynthetic parameters and up-regulated the antioxidant system by improving the activities of antioxidant enzymes and the content of non-enzymatic components. In addition, the application of Kn and Spd resulted in significant improvement in the content of sugars, proline, and glycine betaine, ameliorating the decline in relative water content. Oxidative stress parameters including hydrogen peroxide, superoxide, lipid peroxidation, lipoxygenase activity, and electrolyte leakage increased due to Cd stress; however, the application of Kn and Spd imparted a significant decline in all these parameters. Further, reduced Cd uptake was also observed due to Kn and Spd application. Total phenols and flavonoids also increased due to Kn and Spd treatments under normal as well as Cd stress conditions, which may have further helped with the elimination of reactive oxygen species. Reduction in the activity of nitrate reductase and the content of nitrogen was ameliorated due to the exogenous application of Kn and Spd. Therefore, the exogenous application of Kn and Spd benefited Vigna angularis counteracting the damaging effects of Cd stress by up-regulating the tolerance mechanisms, including antioxidant and osmolyte metabolism.

“…Polyamines (PAs) are low molecular weight aliphatic nitrogenous bases containing two or more amino groups, and they have potent biological activity (Xu et al, 2009; Vuosku et al, 2018). They are widely distributed in eukaryotic and prokaryotic cells (Liu et al, 2017; Mustafavi et al, 2018). In living organisms, PAs mainly exist in free (F-PAs), covalently conjugated (CC-PAs) or non-covalently conjugated (NCC-PAs) forms (Gholami et al, 2013).…”

Polyamine Function in Plants: Metabolism, Regulation on Development, and Roles in Abiotic Stress Responses

et al. 2019

Polyamines (PAs) are low molecular weight aliphatic nitrogenous bases containing two or more amino groups. They are produced by organisms during metabolism and are present in almost all cells. Because they play important roles in diverse plant growth and developmental processes and in environmental stress responses, they are considered as a new kind of plant biostimulant. With the development of molecular biotechnology techniques, there is increasing evidence that PAs, whether applied exogenously or produced endogenously via genetic engineering, can positively affect plant growth, productivity, and stress tolerance. However, it is still not fully understood how PAs regulate plant growth and stress responses. In this review, we attempt to cover these information gaps and provide a comprehensive and critical assessment of the published literature on the relationships between PAs and plant flowering, embryo development, senescence, and responses to several (mainly abiotic) stresses. The aim of this review is to summarize how PAs improve plants' productivity, and to provide a basis for future research on the mechanism of action of PAs in plant growth and development. Future perspectives for PA research are also suggested.

“…The putrescine, spermidine and spermine are the main polyamines in plant cells. Many studies exhibit that polyamines could act as cellular signals involved in cross talk with hormonal pathways such as abscisic acid regulation of abiotic stress responses (Mustafavi et al, 2018). A striking increase of polyamines occurs under the deprivation of cations such as K + and Mg 2+ .…”

Polyamines are new plant growth regulators and intracellular messengers that regulate plant growth, development, and responses to abiotic environmental stresses. However, little is known about the impact of different polyamines on physiological and biochemical processes of field-grown plants exposed to water deficit stress. A two-year field experiment was conducted as a split-plot based on a randomized complete block design with four replications. Water treatments (Irrigation after 70 and 170 mm evaporation from class A evaporation pan) were assigned to main plots, and foliar application of polyamines including Putrescine, Spermidine and Spermine (at 0 and 0.1 mM) was apportioned to subplots. Average of two years results showed that compared with control, water stress significantly (P < 0.05) reduced adenosine three phosphate (ATP), chlorophyll content index (CCI) and chlorophyll stability index (CSI), rubisco activity, efficiency of photosystem II (Fv/Fm), endogenous polyamine contents, membrane stability index (MSI), nitrogen (N 2 ), potassium (K + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), and grain yield, while polyamine oxidase activity, antioxidant enzymes activity, reactive oxygen species (ROS) and lipid peroxidation (MDA) increased significantly (P < 0.05) upon exposure to water deficit stress. However, exogenous application of polyamines improved ATP content, CCI, CSI, rubisco activity, Fv/Fm, endogenous polyamine content, MSI, antioxidant enzymes activity, N 2 , K + , Ca 2+ , Mg 2+ , and grain yield, while decreased ROS level and MDA content. Compared with the other polyamines, Putrescine showed better effects on physiological, biochemical and agronomical performance in mung bean plants under both irrigation treatments.
