“…PAs exert influence in the plant life cycle, including cell division and elongation, morphogenesis, seed germination, flowering, and senescence (Igarashi and Kashiwagi, 2000;Bais and Ravishankar, 2002;Yoda et al, 2006;Wimalasekera et al, 2011;Gupta et al, 2013). Furthermore, PAs also have impact on plants in response to diverse abiotic stresses, such as salinity (Zapata et al, 2004;Shu et al, 2012), drought (Yang et al, 2007;Li et al, 2015), oxidative stress (Rider et al, 2007;Puyang et al, 2015), high temperature Mostofa et al, 2014), and chilling stress (Nayyar, 2005;Yamamoto et al, 2012).…”

“…During plant responses to various stresses or stimuli, NO and H 2 O 2 production often occur in parallel or in short succession (Bright et al, 2006;Pasqualini et al, 2009). Interestingly, evidence has been found suggesting that H 2 O 2 can be also generated via PA catabolic pathways, through diamine oxidase (DAO) and polyamine oxidase (PAO) activities (Martin-Tanguy, 2001;Kusano et al, 2007;Hussain et al, 2011;Gupta et al, 2013). In Zea mays, PAO modulates H 2 O 2 production during wound healing (Angelini et al, 2008).…”

Polyamines (PAs) and nitric oxide (NO) are vital signals in modulating plant response to abiotic stress. However, to our knowledge, studies on the relationship between NO and PAs in response to cold stress in tomato are limited. Accordingly, in this study, we investigated the effects of putrescine (Put) and spermidine (Spd) on NO generation and the function of Spd-induced NO in the tolerance of tomato seedling under chilling stress. Spd increased NO release via the nitric oxide synthase (NOS)-like and nitrate reductase (NR) enzymatic pathways in the seedlings, whereas Put had no such effect. Moreover, H 2 O 2 might act as an upstream signal to stimulate NO production. Both exogenous NO donor (sodium nitroprusside (SNP)) and Spd enhanced chilling tolerance in tomato, thereby protecting the photosynthetic system from damage. Compared to chilling treatment alone, Spd enhanced the gene expressions of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX), and their enzyme activities in tomato leaves. However, a scavenger or inhibitor of NO abolished Spd-induced chilling tolerance and blocked the increased expression and activity due to Spd of these antioxidant enzymes in tomato leaves under chilling stress. The results showed that NO induced by Spd plays a crucial role in tomato's response to chilling stress.

“…(Young and Galston 1983;Flores and Galston 1982) which is beneficial for the amelioration in field of agronomy. Furthermore, these water-soluble polyamines are strongly basic, aliphatic multivalent cationic nitrogenated molecule which acquires a highly protonated primary amino groups at physiological pH (Gupta et al 2013(Gupta et al , 2014. Owing to the high affinity of bacterial cells towards these polycationic aliphatic amines, like other cationic synthetic polymers, they may be able to interact with the negatively charged phospholipids (membrane heads) and membrane bound proteins, ion channels, leading to alteration of packing arrangement of the bacterial cells (Schuber 1989).…”

Integration of biology with nanotechnology is now becoming attention-grabbing area of research. The antimicrobial potency of silver has been eminent from antiquity. Due to the recent desire for the enhancement of antibacterial efficacy of silver, various synthesis methods of silver in their nano dimensions are being practiced using a range of capping material. The present work highlights a facile biomimetic approach for production of silver nanoparticle being capped and stabilized by putrescine, possessing a diameter of 10-25 ± 1.5 nm. The synthesized nanoparticles have been analyzed spectrally and analytically. Morphological studies are carried out by high-resolution transmission electron microscopy and crystallinity by selected area electron diffraction patterns. Moreover, the elemental composition of the capped nanoparticles was confirmed by energy-dispersive X-ray spectroscopy analysis. A comparative study (zone of inhibition and minimum inhibitory concentration) regarding the interactions and antibacterial potentiality of the capped silver nanoparticles with respect to the bare ones reveal the efficiency of the capped one over the bare one. The bacterial kinetic study was executed to monitor the interference of nanoparticles with bacterial growth rate. The results also highlight the efficacy of putrescine-capped silver nanoparticles as effective growth inhibitors against multi-drug resistant human pathogenic bacterial strains, which may, thus, potentially be applicable as an effective antibacterial control system to fight diseases.

“…Estas são substâncias de baixo peso molecular, policatiônicas, alifáticas e nitrogenadas (Takahashi & Kakehi, 2010;Hussain et al, 2011;Fariduddin et al, 2013), que podem ser utilizadas por algumas plantas na defesa contra condições adversas. O interesse pelas poliamidas se deve ao fato de elas apresentarem vias metabólicas interconectadas com diferentes rotas envolvidas na formação de moléculas e metabólitos relevantes para sinalizar as respostas das plantas ao estresse (Duan et al, 2008;Takahashi & Kakehi, 2010;Fariduddin et al, 2013;Gupta et al, 2013;Filippou et al, 2014). Trabalhos recentes destacam que as poliaminas estão envolvidas na proteção das plantas à restrição hídrica e à salinidade (Takahashi & Kakehi, 2010;Hussain et al, 2011;Gupta et al, 2013;Filippou et al, 2014;Kotakis et al, 2014).…”

Resumo -O objetivo deste trabalho foi verificar o efeito da aplicação da poliamina putrescina no acúmulo de prolina e no crescimento inicial de plântulas de guandu cultivadas sob estresse hídrico ou salino, e avaliar se esta poliamina pode ser usada como atenuadora desses estresses. Sementes de duas cultivares de guandu, BRS Mandarim e Caqui, foram germinadas em caixas gerbox forradas com papel de filtro umedecido com 0,0, -0,2, -0,3, -0,4, -0,5 MPa de PEG 6000 ou 0, 20, 40, 60, 80 e 120 mmol L -1 de NaCl, na ausência (0 mmol L -1 ) ou na presença (0,5 mmol L -1 ) de putrescina. Utilizou-se o delineamento inteiramente casualizado, em arranjo fatorial 2x5x2 e 2x6x2 (duas cultivares, cinco níveis de deficiência hídrica ou seis níveis de estresse salino, e presença ou ausência de putrescina), com quatro repetições. O crescimento das plântulas é acentuadamente reduzido pelas condições de restrição hídrica e salinidade. A putrescina exógena incrementa, sob ambos os estresses, os teores de prolina nas plântulas de guandu, especialmente na cultivar BRS Mandarin, e atenua os efeitos da deficiência hídrica moderada nas cultivares estudadas. Os estresses de restrição hídrica e de salinidade causam acúmulo de prolina na parte aérea e nas raízes de ambas as cultivares. A prolina pode ser considerada um bom indicador bioquímico e fisiológico desses estresses em plântulas de guandu.Termos para indexação: Cajanus cajan, indicador bioquímico, poliamina, restrição hídrica, salinidade, solutos compatíveis.Growth and proline content in pigeon pea seedlings subjected to osmotic stress and to exogenous putrescine Abstract -The objective of this work was to verify the effect of the application of the polyamine putrescine on the accumulation of proline and on the early seedling growth of pigeon pea subjected to water or salt stress, and to evaluate whether this polyamine can be used to alleviate these stresses. Seeds of two cultivars of pigeon pea, BRS Mandarim and Caqui, were germinated in gerbox boxes lined with filter papers soaked with 0.0, -0.2, -0.3, -0.4, -0.5 MPa PEG 6000 or 0, 20, 40, 60, 80, and 120 mmol L -1 NaCl, in the absence (0 mmol L -1 ) or presence (0.5 mmol L -1 ) of putrescine. A completely randomized design was used, in a 2x5x2 and 2x6x2 factorial arrangement (two cultivars, five levels of drought or six levels of salt stress, and presence or absence of putrescine), with four replicates. Seedling growth is highly reduced by water restriction and salinity conditions. Exogenous putrescine increases, under both stresses, the proline contents in pigeon pea seedlings, especially in the cultivar BRS Mandarin, and alleviates the effects of moderate water deficiency on the studied cultivars. Water restriction and salinity stresses cause accumulation of proline content in shoots and roots of both cultivars. Proline can be considered a good biochemical and physiological indicator of these stresses in pigeon pea seedlings.Index terms: Cajanus cajan, biochemical indicator, polyamine, water restriction, salinity, compatible so...
