“…Similar to this research findings, Beyaz et al (2011) reported that fresh-dry weight decreased due to increasing salinity in sainfoin, another important forage crops, in their study in vitro study. Uchiya et al (2016) stated that root dry weight of L. corniculatus seedling decrease depend on increased salinity levels (from 0 to 150 mM). Moreover, Bao et al (2014) noted that depend on increased salt stress (from 0 to 200 mM) shoot dry weight of L. corniculatus seedling decreased.…”

Lotus corniculatus L. is one of the agronomically and economically important perennial legume forage species with moderately salt-tolerant. It is well known that even the cultivars of the same species in plants have different responses in salinity. However, studies on the salt response of L. corniculatus and its cultivars, which are more advantageous than other forage crops such as white clover (Trifolium repens) and alfalfa (Medicago sativa L.), in the use of marginal agricultural lands affected by abiotic stress factors such as salinity, are limited. Under salt stress, the most crucial phases of the plant life cycle that are directly related to the survival of the plant are seed germination, growth, and vigour. Therefore, this study was carried out to determine the germination and growth responses of L. corniculatus cultivar 'Leo', which is known to have higher tannin content than other cultivars, under NaCl-derived salt stress in vitro. For this purpose, L. corniculatus seeds were cultured in MS (Murashige and Skoog/Gamborg) medium containing 0, 40, and 80 mM NaCl for 14 days. Seed germination percentage, mean germination time, germination rate index, shoot-root length, root to shoot length ratio, shoot-root fresh dry weight, shoot-root dry matter, the ratio of root to shoot dry matter, shoot-root water content and seedling vigour index parameters were measured. According to the results of the research, the germination percentage did not change in the applied NaCl treatments, but the germination rate decreased. However, shoot length decreased and root length increased. Although there was no statistically significant change in shoot and root fresh-dry weight, both decreased in 80 mM NaCl treatment. The shoot and root dry matter increased and the water content decreased. Also, the seedling viability index decreased. In 40 mM NaCl treatment, on the other hand, there was an increase in shoot fresh-dry weight, dry matter ratio and seedling viability index with the positive effect of low dose. Within the scope of this study, comprehensive information was presented for L. corniculatus (cultivar 'Leo'), an important forage plant, in terms of germination and seedling growth under salt stress.

“…The RLR describes the plant potential for soil resource acquisition, and it is composed by the root mass fraction (RMF) and the specific root length (SRL). These functional traits may be affected by drought and/or salinity, according to several field and laboratory studies (Bayuelo-Jimenez et al, 2003; Meier et al, 2008; Poorter et al, 2009; Miranda et al, 2010; Rewald et al, 2013; Nguyen et al, 2014; Uchiya et al, 2016; Eziz et al, 2017). In contrast, reports about the effect of AM inoculations on SLA and LMF in plants grown under drought or saline stress are less abundant and show dispar results according to the plant species (Miranda et al, 2011; Abdel-Fattah et al, 2013; Romero-Munar 2019).…”

We aimed at exploring the plant functional traits whose stress-induced plasticity is altered by the presence of AM fungi, considering the direction of their changes. We also sought for a coordinated variation of plant biomass and functional traits, during plant adaptation to environmental stressors, and the role of AM status on the variation. We performed a meta-analysis across 114 articles spanning 110 plant species or cultivars. We quantified the size effect of AM symbiosis on the stress-induced plasticity of several reported and calculated functional traits, and using linear mixed model analysis (LMM). Correlation between traits plasticity and total biomass variation were also performed through LMM. The literature search and further selection yielded seven functional traits, extracted from 114 laboratory studies, including 888 observations and 110 plant species/cultivars. Evidence for significant effects of predictor variables (type of stress, AM symbiosis and/or their interaction) on plasticity were found for three of these functional traits: leaf-area ratio (LAR), root mass fraction (RMF) and root-shoot (R:S) ratio. Our results provided evidence to accept the hypothesis that AM fungal inoculation may reduce the phenotypic plasticity of important plant functional traits leaf area ratio (LAR), root mass fraction (RMF) and root-shoot (R:S) ratio, by decreasing its magnitude. We also found a weak correlation between traits plasticity and total biomass variation. Although our literature search and data collection were intensive and our results robust, the scope of our conclusions is limited by the agronomical bias of plant species targeted by the meta-analysis. Further knowledge on non-cultivable plant species and better understanding of the mechanisms ruling resources allocation in plants would allow more generalized conclusions.

“…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.
