ABSTRACT: Glycines, Proline, Sucrose and Trehalose have been found to confer a big level of osmotic tolerance. In stress conditions, these osmoprotectants accumulate in the Rhizobium to overcome the osmotic shocks and proliferate in the given habitat. The accumulation of these osmolytes raises the internal osmotic pressure, which protects against stress. In this paper these osmoprotectants were determined from the nodules of Cajanus cajan plant grown in presence of NaCl and Glyphosate. It was found that, these osmolytes were accumulated in more quantity with increase in stress. Effect of these osmolytes on the growth of Rhizobium was also studied.
