Drought and high salinity are responsible for large decreases in crop productivity all over theworld [1]. These losses of crop yield result from limitations of plant development through excessive ion accumulation, water deficit and mineral deficiencies [2]. Under these prevalent stresses, tolerant plants adopt various strategies with a wide range of biochemical to physiological and morphological adaptations [3]. Morphological ones include modifications in growth and allocation of assimilates towards roots for an efficient exploitation of soil nutrients [4]. The physiological strategy is represented by a higher selectivity for K+ over Na+ [5], an increase in K+-use efficiency [6], and the synthesis of organic osmolytes, with low molecular weight, for osmo-protection [7]. These osmolytes are sugars, polyols, amino acids, tertiary and quarternary ammonium, and tertiary sulphonium compounds [8]. [ABSTRACT FROM AUTHOR] |
