“…In higher plants, PAs are predominantly present in their free form. The most common PAs in higher plants are Put, Spd, Spm, thermospermine (Tspm) (Kim et al, 2014; Sobieszczuk-Nowicka, 2017; Takahashi et al, 2017b), and cadaverine (Cad) (Regla-Márquez et al, 2015; Nahar et al, 2016) (Table 1). Other PAs are found only in certain plants or under special conditions.…”

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.

“…Polyamines, also known as biogenic amines, are low molecular weight compounds involved in plant responses to abiotic and biotic stresses (Hussain et al, 2011), as well as in the processes of cell growth and differentiation (Regla-Márquez et al, 2016). They are also linked to molecular plant defense mechanisms involved in the scavenging and/or generation of free radicals, regulation of gene expression, and formation of toxic defense products (Cai et al, 2015).…”

The horticultural industry demands high-quality resources to achieve excellence in yield and optimal revenues. Nitrogen is a pivotal nutrient to accomplish these goals for plant growth and product quality. However, competition for water in semi-arid regions can force the use of brackish waters, which can impair N uptake. The lower N uptake can be due to several reasons, such as an antagonism between ions, an absence of ATP, and/or alteration of N metabolism. The effect of supplying N as alone or in combination with , coupled with low or high salinity (8 or 20 mM NaCl), has been studied in sweet pepper fruits ( Capsicum annuum L. cv. Melchor). The application of at high salinity affected chromatic parameters (a ∗ , b ∗ , and C ∗ ), while chlorophyll a and b levels declined and β-carotene increased. The concentrations of P, K, Ca, Mg, and Cu were reduced in the fruits of plants irrigated with . The concentration of Na was only reduced when was supplied. Likewise, the concentration of total phenolics was also reduced at high salinity. However, total protein was unaffected. The amino acid profile was altered by the supply of , which reduced the concentrations of histidine and phenylalanine. Moreover, the concentrations of putrescine and cadaverine were increased by at high salinity, whereas that of cadaverine was reduced by at low salinity. The observed changes in fruit quality triggered by salinity, under the conditions of this study, should be borne in mind for this crop with regard to the envisaged palliative effect of the supply of N- .

“…Polyamines are abundant nitrogen-containing metabolites that mediate a wide variety of physiological functions in eukaryotes, bacteria, and archaea. In higher plants, the most common polyamines are the diamines putrescine and cadaverine, the triamine spermidine, and the tetraamine spermine (Kim et al, 2014; Regla-Márquez et al, 2016; Nahar et al, 2016; Sobieszczuk-Nowicka, 2017; Takahashi et al, 2018) ( Figure 1A ). These compounds play a central role in many aspects of plant physiology by influencing transcription, RNA modification, protein synthesis, enzyme activity, and signalling pathways (Evans and Malmberg, 1989; Galston et al, 1997; Kusano et al, 2007; Kusano et al, 2008; Takahashi and Kakehi, 2010; Wimalasekera et al, 2011; Sagor et al, 2015).…”

Polyamines have vital functions in organisms, including bacteria, plants, and animals, with key roles in growth, development, and stress responses. Spermine/spermidine N1-acetyl transferases (SSATs) regulate polyamine abundance by catalysing their N-acetylation, thereby reducing the pool of polyamines and producing other bioactive components. The regulatory mechanisms controlling SSAT enzymes are incompletely understood. Here, we investigate the biological role and regulation of the two SSAT isoforms present in Arabidopsis thaliana, N-ACETYLTRANSFERASE ACTIVITY (NATA) 1 and 2. We show that NATA2 is a heat-stable isoform, induced in response to heat. Intriguingly, a nata2 knockout mutation proved beneficial for growth and pathogen defence under heat stress in Arabidopsis, aligning with the stress-mitigating effect of polyamines. In contrast, the double knockout of nata1 and nata2 was lethal, highlighting the essential role of basal SSAT activity. Our numerous crystal structures of both NATAs, supported by functional assays, revealed that stress-produced acidic metabolites can selectively inhibit polyamine acetylation by occupying the NATA substrate-binding pocket. This environment-responsive regulation mechanism may allow Arabidopsis to adjust the deleterious action of NATAs under stress conditions, without eliminating the enzyme. More generally, metabolite-ensemble inhibition may be a novel paradigm for non-genetic feedback regulation of plant enzymes.
