“…Post-translational covalent linkage of PAs to proteins is catalyzed by a class of enzymes known as transglutaminases (EC 2.3.2.13), which have been localized both intra-and extracellularly (Folk 1980). Different plant species may contain varied proportions of free and conjugated PAs (Bagni & Tassoni 2001). Species of tobacco and barley may contain up to 90% of the conjugated form of PAs whereas in carrot cell cultures, it accounts less than 10% (Torrigiani et al 1987).…”

“…Species of tobacco and barley may contain up to 90% of the conjugated form of PAs whereas in carrot cell cultures, it accounts less than 10% (Torrigiani et al 1987). Martin-Tanguy (2001) believed that PA conjugating with hydroxycinnamic acids is important for the control of the intracellular PA concentration and also serves as a source of PA for transport or as a substrate for amino oxidases and peroxidases and also for their interaction with components of the cell wall, especially hemicellulose and lignin (Bagni and Tassoni 2001).…”

“…The concentration of plant PAs varies markedly, depending on the plant species, organ and tissues and also on the developmental stage. They are preferentially detected in actively growing tissues of pants and play pivotal roles in a wide range of plant growth and developmental processes such as cell division, root formation, embryogenesis, organogenesis, floral initiation, leaf senescence, fruit development, and fruit ripening (Bagni & Tassoni 2001;Kusano et al 2008).…”

Polyamines (PAs) are aliphatic polycations that are widespread in living organisms. In this review, we are focusing the correlation between endogenous PA titers and physiological perturbations and on the protective role of various analogues of PAs against abiotic stresses. PAs are involved in many physiological processes, such as cell growth and development and also respond to diverse abiotic stresses. Polyamines level shifts in different ways depending on several factors, such as plant species, tolerance or sensitivity to stress, and duration of stress. Exogenously supplied PAs protected plants from abiotic stress, whereas transgenic plants overexpressing PA biosynthetic genes exhibited stress tolerance. On the other hand, loss-of-function mutant of PA biosynthetic genes, or decrease of PA titers, resulted to decrease stress tolerance.

“…SAM is also an intermediate of ethylene biosynthesis, suggesting a potential relationship between PA and ethylene biosynthesis (Faust and Wang, 1993). Cadaverine is synthesized from lysine by lysine decarboxylase (LDC) (Bagni and Tassoni, 2001;Flores et al, 1989). PAs localize to the cytoplasm as well as organelles such as vacuoles, mitochondria, and chloroplasts (Kusano et al, 2008).…”

A highly oxidative stress-tolerant japonica rice line was isolated by T-DNA insertion mutation followed by screening in the presence of 50 mM H 2 O 2 . The T-DNA insertion was mapped to locus Os09g0547500, the gene product of which was annotated as lysine decarboxylase-like protein (GenBank accession No. AK062595). We termed this gene OsLDC-like 1, for Oryza sativa lysine decarboxylase-like 1. The insertion site was in the second exon and resulted in a 27 amino acid N-terminal deletion. Despite this defect in OsLDC-like 1, the mutant line exhibited enhanced accumulation of the polyamines (PAs) putrescine, spermidine, and spermine under conditions of oxidative stress. The generation of reactive oxygen species (ROS) in the mutant line was assessed by qRT-PCR analysis of NADPH oxidase (RbohD and RbohF), and by DCFH-DA staining. Cellular levels of ROS in osldc-like 1 leaves were significantly lower than those in the wild-type (WT) rice after exposure to oxidative, high salt and acid stresses. Exogenouslyapplied PAs such as spermidine and spermine significantly inhibited the stress-induced accumulation of ROS and cell damage in WT leaves. Additionally, the activities of ROS-detoxifying enzymes were increased in the homozygous mutant line in the presence or absence of H 2 O 2 . Thus, mutation of OsLDC-like 1 conferred an oxidative stress-tolerant phenotype. These results suggest that increased cellular PA levels have a physiological role in preventing stress-induced ROS and ethylene accumulation and the resultant cell damage.

“…Smith (1971) (Steiner, 1966;Smith, 1971). In principle, formation pathways are the decarboxylation of amino acids and transamination from aldehydes (Cromwell and Richards, 1966;Steiner, 1966;Steiner et al, 1967;Smith, 1971Smith, , 1975Wink and Hartmann, 1981;Dey et al, 1997;Farquhar et al, 1983;Bagni and Tassoni, 2001;Dudareva et al, 2013). Most measurements addressed the MA content within the tissue of vegetation parts such as fruiting bodies, foliage, and especially blossoms.…”

Ideas and perspectives: on the emission of amines from terrestrial vegetation in the context of new atmospheric particle formation

Abstract. In this article we summarise recent science which shows how airborne amines, specifically methylamines (MAs), play a key role in new atmospheric particle formation (NPF) by stabilising small molecule clusters. Agricultural emissions are assumed to constitute the most important MA source, but given the short atmospheric residence time of MAs, they can hardly have a direct impact on NPF events observed in remote regions. This leads us to the presentation of existing knowledge focussing on natural vegetationrelated MA sources. High MA contents as well as emissions by plants was already described in the 19th century. Strong MA emissions predominantly occur during flowering as part of a pollination strategy. The behaviour is species-specific, but examples of such species are common and widespread. In addition, vegetative plant tissue exhibiting high amounts of MAs might potentially lead to significant emissions. The decomposition of organic material constitutes another, potentially ubiquitous, source of airborne MAs. These mechanisms would provide sources, which could be crucial for the amine's role in NPF, especially in remote regions. Knowledge about vegetation-related amine emissions is, however, very limited, and thus it is also an open question how global change and the intensified cycling of reactive nitrogen over the last 200 years have altered amine emissions from vegetation with a corresponding effect on NPF.
