Waterlogging Stress Physiology in Barley

Barley (Hordeum vulgare L.) is the most susceptible cereal species to excess moisture stress. Waterlogging-induced hypoxia causes major morphological, physiological, and metabolic changes, some of which are regulated by action plant growth regulators signal molecules including nitric oxide. Recent studies have evidenced participation phytoglobins in attenuating hypoxic stress during conditions excessive through their ability scavenge oxide influence synthesis response regulators. This review will highlight cellular changes linked responses waterlogging with emphasis on phytoglobins.
