“…Maiale et al (2004) found that salt stress decreased Spd synthase activity in salt tolerant rice, and that salt stress plus cyclohexylamine, an inhibitor of Spd synthase, did not reduce Put content, probably due to Spd synthase inhibition. As shown in our research (Table 1), Spm accumulated and its accumulation seemed to be a general trend in plants under salt stress (Santa-Cruz et al 1997, Maiale et al 2004, Sanchez et al 2005. The finding that A. thaliana Spm synthase gene AtSPMS was induced by salt shock provides a molecular basis for this conversion (Urano et al 2003).…”

“…There was a negative correlation between proline accumulation and endogenous Put content. In plant responses to salt stress, this correlation between PA and proline was also found in other species, such as tomato (Aziz et al 1998, Santa-Cruz et al 1999, Fraxinus angustifolia callus (Tonon et al 2004) and Lotus glaber (Sanchez et al 2005). One of the explanations for this change is that both PAs and proline compete for glutamate as a common precursor (Santa-Cruz et al 1999, Tonon et al 2004.…”

“…Santa-Cruz et al (1999) reported that a decline in Put content was parallel to proline accumulation in salt tolerant tomato when NaCl concentration increased up to 200 mM. However, Sanchez et al (2005) found that PAs did not always parallel proline accumulation in Lotus glaber under long-term salt stress. Furthermore, Tonon et al (2004) reported that proline content highly paralleled Put content under non-lethal NaCl concentrations while different changes in proline and Put occurred under lethal NaCl concentration.…”

Proline accumulation was studied in the leaves of Glycine max (L.) Merr. subjected to salt stress in the presence of aminoguanidine (AG, a specific inhibitor of diamine oxidase, DAO) and exogenous putrescine (Put). Both DAO activity and proline content were increased while endogenous Put content was decreased in soybean leaves under 50 to 150 mM NaCl. There was a negative correlation between proline accumulation and endogenous Put content. The addition of AG during NaCl stress inhibited DAO activity, caused Put accumulation and a 15 to 20 % decrease in proline content. Application of 1 mM Put to NaCl solution markedly increased proline content. The promotive effect of Put application could be alleviated by the treatment with Put plus AG. Moreover an application of AG had no effect on proline accumulation in soybean seedlings grown under normal condition. These results indicate that the quantitative contribution of Put degradation to proline formation is 15 to 20 %.Additional key words: Glycine max, NaCl-induced stress, polyamine degradation.

“…Similarly, Das et al (1995), Santa-Cruz et al (1997a), Tonon et al (2004), and Legocka and Kluk (2005) reported that a short period of stress increased the polyamine levels, whereas, under longer stress duration, only a small change in the polyamine levels was observed, showing that polyamine accumulation takes place primarily at the onset of stress. In this regard, polyamines were suggested as short-term salt-tolerance traits in tomato (Santa-Cruz et al 1998) and, thus, can be considered as a biochemical indicator (Sanchez et al 2005).…”

“…Studies on abiotic stress in L. tenuis have been focused principally on NaCl tolerance (Sánchez et al 2005;Sannazzaro et al 2006Sannazzaro et al , 2007Echeverria et al 2008;Uchiya et al, 2016), whereas less studies has addressed its tolerance level to alkaline and mixed salt-alkaline stresses. Alkaline salts have a more severe effect on plant growth than neutral salts.…”

The Salado River Basin region is the most important livestock breeding area in Argentina, wherethe Lotus species has been traditionally cultivated as forages. Nearly 60% of their land surface is dominated by salt-affected soils with severe constraints for crop cultivation. In order to cope with that limitation, farmers have utilized species such as non-native L. tenuis (ex-Lotus glaber), which shows a very good adaptation. As a result, inter-seeding of L. tenuis has been proposed as a strategy of choice for improving forage production in marginal areas. The increase in soil quality by these means is achieved by an increment of the organic matter content, improvement of soil fertility as well as microbial biodiversity. Thus, the introduction of L. tenuis and/or other Lotus genotypes could have enormous benefits for similar constrained lands around the world. We are developing an integrated analysis of the changes that occur in soils under legume production. We will not only analyze the microbial diversity associated, but also soil physical and chemical characteristics and the impact of different legume-microbes association on mitigation of GHG emissions. In addition, we are identifying the main genetic determinants associated with interesting agronomic traits such as plant tolerance against biotic and abiotic stresses and the content of condensed tannins. Our future and present research will build a solid base for the improvement of agronomicallyimportant species and the development of better strategies for the management of constrained lands such as the lowlands in the Argentinean Pampas.
