“…In our study, the activity of PDH was higher in the control condition but gradually decreased under stress. According to Shevyakova et al (2013), ABA suppressed PDH activity when treated to the roots. Dallmier and Stewart (1992) also stated that exogenous ABA declines PDH activity, which is very small, compared to level declined in response to drought stress suggesting that ABA is not the pathway linking drought stress and PDH activity.…”

“…Furthermore, plant polyamine metabolism is also connected with the production of nitric oxide and GABA [Reviewed by Alcazar et al ( 2010 )]. The regulation of polyamine biosynthesis, proline and cytokinins by abscisic acid as well as ethylene during UV-B stress and salt stress has been documented (Rakitin et al, 2009 ; Xue et al, 2009 ; Shevyakova et al, 2013 ).…”

Fungi, as well as the rest of living organisms must deal with environmental challenges such as stressful stimuli. Fungi are excellent models to study the general mechanisms of the response to stress, because of their simple, but conserved, signal-transduction and metabolic pathways that are often equivalent to those present in other eukaryotic systems. A factor that has been demonstrated to be involved in these responses is polyamine metabolism, essentially of the three most common polyamines: putrescine, spermidine and spermine. The gathered evidences on this subject suggest that polyamines are able to control cellular signal transduction, as well as to modulate protein-protein interactions. In the present review, we will address the recent advances on the study of fungal metabolism of polyamines, ranging from mutant characterization to potential mechanism of action during different kinds of stress in selected fungal models.

“…Spd diminished the expression of ferritin gene and consequently the production of reactive oxygen species (ROS). Shevyakova et al (2013) found a protective effect of ABA related to the regulation of proline (Pro), PAs, and cytokinin contents. Under saline conditions, ABA treatment increased free PA content, in roots, whereas that in leaves, could regulate conjugate forms, thus controlling the PA biological functions.…”

Polyamines (PAs) are related to many aspects of the plant’s life cycle, including responses to biotic and abiotic stress. On the other hand, halophytic plants are useful models for studying salt tolerance mechanisms related to the adaptive strategies that these plants present in adverse environments. Furthermore, some halophytes have high economic value, being recommended instead of glycophytes as alternative agricultural crops in salt-affected coastal zones or saline farmlands. In recent years, the understanding of the role of PAs in salt-tolerant plants has greatly advanced. This mini review reports on the advances in the knowledge of PAs and their participation in achieving better salt tolerance in 10 halophytes. PAs are associated with responses to heavy metals in phytoremediation processes using certain salt-tolerant species ( Atriplex atacamensis , A. halimus , Inula chrithmoides , and Kosteletzkya pentacarpos ). In crops with exceptional nutritional properties such as Chenopodium quinoa , PAs may be useful markers of salt-tolerant genotypes. The signaling and protection mechanisms of PAs have been investigated in depth in the extreme halophyte Mesembryanthemum crystallinum and Thellungiella spp., enabling genetic manipulation of PA biosynthesis. In Prosopis strombulifera , different biochemical and physiological responses have been reported, depending on the type of salt (NaCl, Na 2 SO 4 ). Increases in spermidine and spermine have been positively associated with stress tolerance as these compounds provide protection in Cymodocea nodosa , and Solanum chilense , respectively. In addition, abscisic acid and salicylic acid can improve the beneficial effect of PAs in these plants. Therefore, these results indicate the great potential of PAs and their contribution to stress tolerance.
