Exogenous application of ZnO nanoparticles and ZnSO distinctly influence the metabolic response in Phaseolus vulgaris L.

Nanomaterials-mediated contamination (including the highly reactive metal oxides ZnO nanoparticles) is becoming one of the most concerning issues worldwide. In this study, the toxic effects of two chemical species of Zn (ZnO nanoparticles and bulk ZnSO) were investigated in bean plants, following either foliar or soil application, at concentrations from 250 to 2000 mg L using biochemical assays, proteomics and metabolomics. The accumulation of Zn in plant tissues depended on the application type, zinc chemical form and concentration, in turn triggering distinctive morphological, physiological, and redox responses.

Identification of salt-responsive genes from C4 halophyte through suppression subtractive hybridization and expression analysis under individual and combined treatment of salt and elevated carbon dioxide conditions.

Salinization of soil is a prime abiotic stress that limits agriculture productivity worldwide. To Study the mechanisms that halophytes take up to survive under high salt condition is important in engineering salinity stress tolerance in sensitive species. is a halophyte plant that grows in the saline environment and extreme high tidal belt.

Proteomics Revealed Distinct Responses to Salinity between the Halophytes (L.) Dumort and (Roxb).

Plant resistance to salinity stress is one of the main challenges of agriculture. The comprehension of the molecular and cellular mechanisms involved in plant tolerance to salinity can help to contrast crop losses due to high salt conditions in soil. In this study, and , two plants with capacity to adapt to high salinity levels, were investigated at proteome level to highlight the key processes involved in their tolerance to NaCl.

Metabolomic insights into the mechanisms underlying tolerance to salinity in different halophytes.

Salinity is among the most detrimental and diffuse environmental stresses. Halophytes are plants that developed the ability to complete their life cycle under high salinity. In this work, a mass spectrometric metabolomic approach was applied to comparatively investigate the secondary metabolism processes involved in tolerance to salinity in three halophytes, namely S.
