“…The screen of A. thaliana T-DNA insertion lines revealed a reduced NO production to a similar extent in noa1 and half of the CuAO insertional lines ( atao1 , cuao1 , cuao6 , cuao8 , and cuao9 ). This tendency, even if not significant, correlates with the impairment of several CuAO mutant lines in NO synthesis, which reinforces the existing link between PA metabolism and NO production in plants (Tun et al , 2006; Wimalasekera et al , 2011; Scheler et al , 2013; Yang et al , 2014). In our screening system, cuao8-1 displayed a strong and significant reduction of NO production.…”

“…This NOS-like activity is further supported by the expression of recombinant rat NOS in Arabidopsis thaliana and Nicotiana tabacum , which results in increased NO production and higher resistance to biotic and abiotic stresses (Chun et al , 2012; Shi et al , 2012). In addition, several other experimental data support the existence of an oxidative route for NO production in plants, such as external addition of hydroxylamine or polyamines (PAs), which both produce NO in plant cells (Tun et al , 2006; Rümer et al , 2009; Yang et al , 2014; Jeandroz et al , 2016). …”

“…Indeed, this signaling molecule is involved in developmental processes, such as germination or flowering, as well as in the adaptive response to biotic or abiotic stresses (for reviews, see Scheler et al , 2013; Yang et al , 2014; Hichri et al , 2015; Sanz et al , 2015; Simontacchi et al , 2015). Over the last years, the complex mechanisms underlying these effects have been studied in depth, including the NO-dependent post-translational modifications of proteins or the NO crosstalk with phytohormones (see, for example, Astier and Lindermayr, 2012; Freschi, 2013; Mur et al , 2013).…”

“…Rapid NO accumulation was reported after spermidine and spermine treatments without a lag phase, whereas putrescine had little effect in Arabidopsis [49]. In contrast, exogenous polyamines, especially putrescine, induced NO generation in soybean [50]. Reduced NO release was observed in copper amino oxidase 1 knock-out Arabidopsis [51].…”

The main role of polyamines was originally assumed to be as direct protective compounds important under stress conditions. Although in some cases a correlation was found between the endogenous polyamine content and stress tolerance, this relationship cannot be generalized. Polyamines should no longer be considered simply as protective molecules, but rather as compounds that are involved in a complex signaling system and have a key role in the regulation of stress tolerance. The major links in polyamine signaling may be H 2 O 2 and NO, which are not only produced in the course of the polyamine metabolism, but also transmit signals that influence gene expression via an increase in the cytoplasmic Ca 2+ level.Polyamines can also influence Ca 2+ influx independently of the H 2 O 2 -and/or NO-mediated pathways. Furthermore, these pathways may converge. In addition, several protein kinases have been shown to be influenced at the transcriptional or post-translational level by polyamines. Individual polyamines can be converted into each other in the polyamine cycle.In addition, their metabolism is linked with other hormones or signaling molecules. However, as individual polyamines trigger different transcriptional responses, other mechanisms and the existence of polyamine-responsive elements and the corresponding transacting protein factors are also involved in polyamine-related signaling pathways. Highlights:-Polyamines are interconvertible in the polyamine cycle -The statement "the higher the polyamine level the better" cannot be generalized -In stress responses the ratio of signaling to direct protection is more important -Polyamines are also involved in hormonal cross-talk -H 2 O 2 and NO are the major but not the only links in polyamine stress signaling

“…In recent years it has been reported that polyamine catabolism induces the synthesis of NO in different plant organs (Tun et al ; Wimalasekera et al ; Yang et al ; Diao et al ; Agurla et al ). In the catabolism of polyamines, polyamine oxidases and Cu‐containing amine oxidases are involved, and in Arabidopsis thaliana isoform CuAO1 contributes to polyamine‐induced NO biosynthesis, although the mechanism of this process is unknown (Wimalasekera et al ).…”

Plant peroxisomes are subcellular compartments involved in many biochemical pathways during the life cycle of a plant but also in the mechanism of response against adverse environmental conditions. These organelles have an active nitro-oxidative metabolism under physiological conditions but this could be exacerbated under stress situations. Furthermore, peroxisomes have the capacity to proliferateand also undergo biochemical adaptations depending on the surrounding cellular status. An important characteristic of peroxisomes is that they have a dynamic metabolism of reactive nitrogen and oxygen species (RNS and ROS) which generates two key molecules, nitric oxide (NO) and hydrogen peroxide (H 2 O 2 ). These molecules can exert signaling functions by means of post-translational modifications that affect the functionality of target molecules like proteins, peptides or fatty acids. This review provides an overview of the endogenous metabolism of ROS and RNS in peroxisomes with special emphasis on polyamine and uric acid metabolism as well as the possibility that these organelles could be a source of signal molecules involved in the functional interconnection with other subcellular compartments.
