Seed germination requirements and salt stress tolerance of coastal rare species in Sardinia
… metabolic adaptations to overcome environmental stresses. Stress may be physical (e.g. temperature) or chemical (e.g. salinity). Many communities comprise highly specialized species, which have comparatively restricted geographical distributions. The coastal species investigated in this Ph.D. …

A multiomic study to unveil the salt stress tolerance mechanisms in S. pennellii x S. lycopersicum Introgression Lines (ILs) [Uno studio multiomico per svelare i meccanismi di tolleranza allo stress salino nelle linee di introgressione (ILs) di S. pennellii x S. lycopersicum]
Lo stress salino influisce significativamente sul metabolismo delle piante, portando a uno sviluppo ridotto, a una riduzione della produzione e, infine, alla morte della pianta stessa. Molte colture hanno numerosi “parenti selvatici”, capaci di crescere in condizioni subottimali. Solanum pennellii, …

Modulation of soybean and maize antioxidant activities by Caffeic acid and nitric oxide under salt stress
… oxide, exogenously applied caffeic acid and salt stress on the ontioxidant system in cereal (exemplified by maize) and legume (using soybean as an example) plants together with their influence on membrane integrity and cell death. This study investigates changes in H₂O₂ content, root lipid …

Analysis of AtNHX1-expressing transgenic cotton under high salt conditions and in the field
… factors in crop productivity. To improve the salt tolerance in crops, one approach is to increase the solute concentration in the vacuoles of plant cells by sequestering sodium ion (Na+) into the vacuoles of plant cells. Consequently, it would reduce the toxicity of high Na+ in the cytoplasm …

Evolution, function and manipulation of methyl halide production in plants
… found for the hypothesis that HOL contributes to salt stress tolerance via the disposal of excessive amounts of halides. On the contrary, increased HOL activity made 35S::HOL plants more susceptible towards salt stress. Despite the toxicity of methyl halides, differences in HOL activity in hol …

Esi47, a stress-inducible protein kinase gene from Lophopyrum elongatum is involved in plant hormone signaling
The cDNA and genomic DNA clones for the salt stress and abscisic acid (ABA) inducible gene Esi47 were isolated from the salt-tolerant tall wheatgrass species Lophopyrum elongatum . The Esi47 gene encodes a protein kinase with highest amino acid sequence similarity to the NAK group of protein …

Molecular mechanisms of salt and osmotic stress tolerance in Frankia strains isolated from Casuarina trees
… be salinized. The hyper-ionic and hyper-osmotic stresses associated with salt-affected soils threaten the ability of cells to maintain optimal turgor pressure and intracellular ionic concentration for growth and functioning. The nitrogen-fixing soil actinobacterium Frankia shows marked …
