ABSTRACT
A comprehensive knowledge of the molecular mechanisms of plant responses to abiotic stresses, particularly salinity stress, is of underlying importance in plant biology, and can be unveiled through global analyses of both transcripts and proteins. Proteins play an inevitable role in stress acclimation and plant cellular adjustment. Salinity stress causes the modulation of gene expression, resulting in extensive changes in proteins (up/down regulation) involved in ion transport, antioxidant pathway, signal transduction, cellular metabolism, osmolyte synthesis, etc. Thus, proteomics are becoming apparent for application in the field of plant abiotic stress research and play a significant role in determining the key procedures involved in plants’ salinity stress response. Quantitative proteomic tools may help in the rapid identification of novel salinity stress-tolerant “biomarkers”, and provide crucial information for employment in the crop breeding programs by engineering stress-tolerant plants through transgenic technology. Therefore, plant proteomics is a key research tool in developing new technologies for agricultural production and its sustainability.
