1995). In spite of an increase in biomass, plant height and number of tillers (secondary stems in grasses) transgenic wheat plant accumulate considerably low amount of mannitol which elucidated it a relatively minor osmolyte and suggested that it might indirectly enhanced osmotic adjustments and salt tolerance acting as a ROS scavenger (Abebe et al. 2003). Trehalose Trehalose, also known as tremalose or mycose, a nonreducing disaccharide, is widely spread in biological systems contributing desiccation tolerance against multiple abiotic stresses (Bartels and Sunkar 2005).
