Cui J, Pottosin I, Lamade E, Tcherkez G. What is the role of putrescine accumulated under potassium deficiency? PLANT, CELL & ENVIRONMENT 2020; 43:1331-1347.

Abstract
Biomarker metabolites are of increasing interest in crops since they open avenues for precision agriculture, whereby nutritional needs and stresses can be monitored optimally. Putrescine has the potential to be a useful biomarker to reveal potassium (K+ ) deficiency. In fact, although this diamine has also been observed to increase during other stresses such as drought, cold or heavy metals, respective changes are comparably low. Due to its multifaceted biochemical properties, several roles for putrescine under K+ deficiency have been suggested, such as cation balance, antioxidant, reactive oxygen species mediated signalling, osmolyte or pH regulator. However, the specific association of putrescine build-up with low K+ availability in plants remains poorly understood, and possible regulatory roles must be consistent with putrescine concentration found in plant tissues. We hypothesize that the massive increase of putrescine upon K+ starvation plays an adaptive role. A distinction of putrescine function from that of other polyamines (spermine, spermidine) may be based either on its specificity or (which is probably more relevant under K+ deficiency) on a very high attainable concentration of putrescine, which far exceeds those for spermidine and spermine. putrescine and its catabolites appear to possess a strong potential in controlling cellular K+ and Ca2+ , and mitochondria and chloroplasts bioenergetics under K+ stress.

Abstract
Soil salinity is a major environmental constraint that threatens agricultural productivity. Different strategies have been developed to improve crop salt tolerance, among which the effects of polyamines have been well-reported. To gain a better understanding of the cucumber (Cucumis sativus L.) responses to NaCl and unravel the underlying mechanism of exogenous putrescine (Put) alleviating salt-induced damage, comparative proteomic analysis was conducted on cucumber roots treated with NaCl, and/or Put for 7 days. The results showed that exogenous Put restored the root growth inhibited by NaCl. Sixty-two differentially expressed proteins implicated in various biological processes were successfully identified by MALDI-TOF/TOF MS. The four largest categories included proteins involved in defense response (24.2%), protein metabolism (24.2%), carbohydrate metabolism (19.4%), and amino acid metabolism (14.5%). Exogenous Put up-regulated most identified proteins involved in carbohydrate metabolism, implying an enhancement in energy generation. Proteins involved in defense response and protein metabolism were differently regulated by Put, which indicated the roles of Put in stress resistance and proteome rearrangement. Put also increased the abundance of proteins involved in amino acid metabolism. Meanwhile, physiological analysis showed that Put could further up-regulated the levels of free amino acids in salt stressed-roots. In addition, Put also improved endogenous polyamines contents by regulating the transcription levels of key enzymes in polyamine metabolism. Taken together, these results suggest that Put may alleviate NaCl-induced growth inhibition through degradation of misfolded/damaged proteins, activation of stress defense, and the promotion of carbohydrate metabolism to generate more energy.

Polyamines are common players in different facets of plant programmed cell death. Amino Acids 2014; 47:27-44.

Abstract
Programmed cell death (PCD) is a process that occurs throughout the life span of every plant life, from initial germination of the seed to the senescence of the plant. It is a normal physiological milestone during the plant's developmental process, but it can also be induced by external factors, including a variety of environmental stresses and as a response to pathogen infections. Changes in the morphology of the nucleus is one of the most noticeable during PCD but all the components of the plant cell (cytoplasm, cytoskeleton and organelles) are involved in this fascinating process. To date, relatively little is known about PCD in plants, but several factors, among which polyamines (PAs) and plant growth regulators, have been shown to play an important role in the initiation and regulation of the process. The role of PAs in plant PCD appears to be multifaceted acting in some instances as pro-survival molecules, whereas in others seem to be implicated in accelerating PCD. The molecular mechanism is still under study. Here we present some PCD plant models, focusing on the role of the enzyme responsible for PA conjugation to proteins: transglutaminase (TGase), an enzyme linked with the process of PCD also in some animal models. The role of PAs and plant TGase in the senescence and PCD in flowers, leaf and the self-incompatibility of pollen will be discussed and examined in depth.

Abstract
Research on polyamines (PAs) in plants laps a long way of about 50 years and many roles have been discovered for these aliphatic cations. PAs regulate cell division, differentiation, organogenesis, reproduction, dormancy-break and senescence, homeostatic adjustments in response to external stimuli and stresses. Nevertheless, the molecular mechanisms of their multiple activities are still matter of research. PAs are present in free and bound forms and interact with several important cell molecules; some of these interactions may occur by covalent linkages catalyzed by transglutaminase (TGase), giving rise to "cationization" or cross-links among specific proteins. Senescence and programmed cell death (PCD) can be delayed by PAs; in order to re-interpret some of these effects and to obtain new insights into their molecular mechanisms, their conjugation has been revised here. The TGase-mediated interactions between proteins and PAs are the main target of this review. After an introduction on the characteristics of this enzyme, on its catalysis and role in PCD in animals, the plant senescence and PCD models in which TGase has been studied, are presented: the corolla of naturally senescing or excised flowers, the leaves senescing, either excised or not, the pollen during self-incompatible pollination, the hypersensitive response and the tuber storage parenchyma during dormancy release. In all the models examined, TGase appears to be involved by a similar molecular mechanism as described during apoptosis in animal cells, even though several substrates are different. Its effect is probably related to the type of PCD, but mostly to the substrate to be modified in order to achieve the specific PCD program. As a cross-linker of PAs and proteins, TGase is an important factor involved in multiple, sometimes controversial, roles of PAs during senescence and PCD.

Abstract
A key plant response to drought is the accumulation of specific sets of metabolites that act as osmoprotectants, osmolytes, antioxidants, and/or stress signals. An emerging question is: how do plants regulate metabolism to balance the 'competing interests' between metabolites during stress? Recent research connects primary sulfur metabolism (e.g., sulfate transport in the vasculature, its assimilation in leaves, and the recycling of sulfur-containing compounds) with the drought stress response. In this review, we highlight key steps in sulfur metabolism that play significant roles in drought stress signaling and responses. We propose that a complex balancing act is required to coordinate primary and secondary sulfur metabolism during the drought stress response in plants.

Abstract
Studies have revealed in plant chloroplasts, mitochondria, cell walls, and cytoplasm the existence of transglutaminase (TGase) activities, similar to those known in animals and prokaryotes having mainly structural roles, but no protein has been associated to this type of activity in plants. A recent computational analysis has shown in Arabidopsis the presence of a gene, AtPng1p, which encodes a putative N-glycanase. AtPng1p contains the Cys-His-Asp triad present in the TGase catalytic domain. AtPng1p is a single gene expressed ubiquitously in the plant but at low levels in all light-assayed conditions. The recombinant AtPng1p protein could be immuno-detected using animal TGase antibodies. Furthermore, western-blot analysis using antibodies raised against the recombinant AtPng1p protein have lead to its detection in microsomal fraction. The purified protein links polyamines-spermine (Spm) > spermidine (Spd) > putrescine (Put)-and biotin-cadaverine to dimethylcasein in a calcium-dependent manner. Analyses of the gamma-glutamyl-derivatives revealed that the formation of covalent linkages between proteins and polyamines occurs via the transamidation of gamma-glutamyl residues of the substrate, confirming that the AtPng1p gene product acts as a TGase. The Ca(2+)- and GTP-dependent cross-linking activity of the AtPng1p protein can be visualized by the polymerization of bovine serum albumine, obtained, like the commercial TGase, at basic pH and in the presence of dithiotreitol. To our knowledge, this is the first reported plant protein, characterized at molecular level, showing TGase activity, as all its parameters analyzed so far agree with those typically exhibited by the animal TGases.

Abstract
The esophageal epithelium is subject to damage from bile acid reflux that promotes normal tissue injury resulting in the development of Barrett's epithelium. There is a selection pressure for mutating p53 in this preneoplastic epithelium, thus identifying a physiologically relevant model for discovering novel regulators of the p53 pathway. Proteomic technologies were used to identify such p53 regulatory factors by identifying proteins that were overexpressed in Barrett's epithelium. A very abundant polypeptide selectively expressed in Barrett's epithelium was identified as anterior gradient-2. Immunochemical methods confirmed that anterior gradient-2 is universally up-regulated in Barrett's epithelium, relative to normal squamous tissue derived from the same patient. Transfection of the anterior gradient-2 gene into cells enhances colony formation, similar to mutant oncogenic p53 encoded by the HIS175 allele, suggesting that anterior gradient-2 can function as a survival factor. Deletion of the C-terminal 10 amino acids of anterior gradient-2 neutralizes the colony enhancing activity of the gene, suggesting a key role for this domain in enhancing cell survival. Constitutive overexpression of anterior gradient-2 does not alter cell-cycle parameters in unstressed cells, suggesting that this gene is not directly modifying the cell cycle. However, cells overexpressing anterior gradient-2 attenuate p53 phosphorylation at both Ser(15) and Ser(392) and silence p53 transactivation function in ultraviolet (UV)-damaged cells. Deletion of the C-terminal 10 amino acids of anterior gradient-2 permits phosphorylation at Ser(15) in UV-damaged cells, suggesting that the C-terminal motif promoting colony survival also contributes to suppression of the Ser(15) kinase pathway. These data identify anterior gradient-2 as a novel survival factor whose study may shed light on cellular pathways that attenuate the tumor suppressor p53.

Abstract
Corolla life span of undetached flowers of Nicotiana tabacum was divided into stages from the closed corolla (stage 1) through anthesis (stage 5) to death (stage 9). Senescence began around stage 6 in the proximal part, concomitantly with DNA laddering. Nuclear blebbing, DNA laddering, cell wall modification, decline in protein, water, pigment content and membrane integrity were observed during senescence and PCD. Transglutaminase activity was measured as mono- and bis-derivatives of putrescine (mono-PU; bis-PU) and bis-derivatives of spermidine (bis-SD). Bis-derivatives decreased with the progression of senescence, while mono-PU increased during early senescence; derivatives were present in different amounts in the proximal and distal parts of the corolla. In excised flowers, exogenous spermine delayed senescence and PCD, and caused an increase in free and acid-soluble conjugated PA levels. Bis-PU was the most abundant PA-derivative before DNA laddering stage; thereafter, bis-PU generally decreased and mono-PU became the most abundant derivative.

Abstract
The human oesophageal epithelium is subject to damage from thermal stresses and low extracellular pH that can play a role in the cancer progression sequence, thus identifying a physiological model system that can be used to determine how stress responses control carcinogenesis. The classic heat shock protein HSP70 is not induced but rather is down-regulated after thermal injury to squamous epithelium ex vivo; this prompted a longer-term study to address the nature of the heat shock response in this cell type. An ex vivo epithelial culture system was subsequently used to identify three major proteins of 78, 70, and 58 kDa, whose steady-state levels are elevated after heat shock. Two of the three heat shock proteins were identified by mass spectrometric sequencing to be the calcium-calmodulin homologue transglutaminase-3 (78 kDa) and a recently cloned oesophageal-specific gene called C1orf10, which encodes a 53-kDa putative calcium binding protein we have named squamous epithelial heat shock protein 53 (SEP53). The 70-kDa heat shock protein (we have named SEP70) was not identifiable by mass spectrometry, but it was purified and studied immunochemically to demonstrate that it is distinct from HSP70 protein. Monoclonal antibodies to SEP70 protein were developed to indicate that: (a) SEP70 is induced by exposure of cultured cells to low pH or glucose starvation, under conditions where HSP70 protein was strikingly down-regulated; and (b) SEP70 protein exhibits variable expression in preneoplastic Barrett's epithelium under conditions where HSP70 protein is not expressed. These results indicate that human oesophageal squamous epithelium exhibits an atypical heat shock protein response, presumably due to the evolutionary adaptation of cells within this organ to survive in an unusual microenvironment exposed to chemical, thermal and acid reflux stresses.

Abstract
Biogenic amines are conveniently divided into aliphatic monoamines, aliphatic di- and polyamines and aromatic amines. These compounds are shown to fulfill an array of roles in cellular metabolism. Thus, amines are needed for growth and development and their metabolism appears to be coordinated with the cell cycle. Di- and polyamines, among which are putrescine, spermidine and spermine, are ubiquitous polycationic molecules that occur in all living cells. However, plants accumulate a number of specific related compounds under free or conjugated forms. In plant tissues, the molecular diversity combined with the fact that amine contents are highly responsive to developmental and environmental signals encouraged analysts to develop specific procedures for their isolation and characterization. The main goals were to develop high performance routine procedures in terms of selectivity, repeatability and detectability with minimum running costs. Domains of application concern not only fundamental aspects of amine biochemistry and physiology in plants but also increasing needs in the control of food and beverage quality from plant origin. The present review reports the most recent advances in extraction, identification and quantitation of amines in plant tissues with special interest in the analysis of original and uncommon metabolites. Emphasis is directed towards chromatographic and electrophoretic separation methodologies and new detection technologies of both derivatized and underivatized compounds including photometry, fluorometry, amperometry and mass spectrometry.
