Title

The physiological response and water relationships in sweet pepper when stopping the activity of root Aquaporin's in drought stress

Pages

  275-287

Abstract

 Aquaporins are the main integral membrane proteins in the plasma membrane, that facilitate transport of water, carbon dioxide, and other small soluble material across the membrane. The aim of this study was to investigate the role of root aquaporins on the physiological, biochemical and biochemical changes and water relations under drought stress. For this purpose, a study was conducted in a completely randomized design on sweet pepper (Ps 301) under drought stress in a hydroponic medium. Sweet pepper plants were grown in hydroponically controlled condition and exposed to drought stress by applying polyethylene glycol (6000) and stopping the activity of aquaporin, using 50 mM of HgNO3. The results showed that in the presence of aquaporins, fresh and dry weight of root and shoot, relative humidity (22%), protein (47%), sodium content (29%), potassium (13%), and abscisic acid (19 %) increased. Also, in the absence of aquaporins under drought stress conditions, the negative potential of root water (57 %), the increase in the amount of proline (1. 2 times), the content of abscisic acid (12%) and the Phenolic content (89. 7%) as a protective factor in the cell against free radicals were observed. Based on the results obtained from drought stress and stopping the activity of aquaporins, the role of Water channels in osmotic regulation can be explained by the transfer of water and decreasing the deleterious effect of stress.
