Drought, salt, and temperature stress-induced metabolic rearrangements and regulatory networks (2012, positive): “PAs have been implicated in protecting membranes and alleviating oxidative stress (Groppa and Benavides, 2008; Alcazar et al., 2011; Hussain et al., 2011) but their specific function in stress tolerance is not well understood.”
Abiotic Stress Responses in Plants: Unraveling the Complexity of Genes and Networks to Survive (2013, background): “Gill and Tuteja [234] stated that, while increase Put accumulation may have a protective role against AOS in plants, enhanced Put turnover can actually make them more vulnerable to increased oxidative damage.”
Mechanism of Salinity Tolerance in Plants: Physiological, Biochemical, and Molecular Characterization (2014, background): “The main aim of this review is to discuss research advances on the complex physiological and molecular mechanisms that are involved in plant salinity tolerance.”
Molecular Mechanism of Heavy Metal Toxicity and Tolerance in Plants: Central Role of Glutathione in Detoxification of Reactive Oxygen Species and Methylglyoxal and in Heavy Metal Chelation (2012, background): “They have the capacity for scavenging free radicals and ROS [183], thus exerting a strong antioxidant function during various types of stress [184].”
Chilling tolerance in maize: agronomic and physiological approaches (2009, background): “Polyamine pretreatment of a cold-sensitive cultivar alleviated chilling injury in different species (Groppa and Benavides 2008) including maize (Cao et al.”
Polyamines: molecules with regulatory functions in plant abiotic stress tolerance (2010, methodology): “…using exogenous polyamine application and/or inhibitors of enzymes involved in polyamine biosynthesis, pointed to a possible role of these compounds in plant adaptation/defence to several environmental stresses (for a review, Bouchereau et al. 1999; Alcázar et al. 2006b; Groppa and Benavides 2008).”
Polyamines: potent modulators of plant responses to stress (2013, background): “Involvement of polyamines in plant response to abiotic stress Several studies have shown that PA accumulation occurs under abiotic stresses including drought, salinity, low temperature, heavy metals, and PQ (Pang et al. 2007; Groppa & Benavides 2008).”
Effect of arginine and urea on polyamines content and growth of bean under salinity stress (2008, background): “Groppa and Benavides (2008) reported that the rise in Put is mainly attributed to the increase in arginine decarboxylase (ADC) activity as consequence of the activation of ADC genes and their mRNA levels.”
Biochemical and physiological changes in jack bean under mycorrhizal symbiosis growing in soil with increasing Cu concentrations (2010, background): “Several nitrogenous metabolites, such as amino acids, polyamines and diverse amino acid-derived molecules can bind metal cations or scavenge ROS formed by excessive metal concentrations in cells (Groppa and Benavides, 2008).”
Polyamines: essential factors for growth and survival (2008, background): “There is an extensive literature describing the correlation of changes in polyamine levels and physiological perturbations and on the protective eVect of polyamines on environmental stresses (see reviews Alcázar et al. 2006; Groppa and Benavides 2007; Liu et al. 2007, and references therein).”
