Abstract

The present study was conducted to understand the role of osmolytes under saline stress. In order to determine the role of osmolytes the Oscillatoria willei was treated with different concentrations of NaCl viz., 0.2, 0.4, 0.6 and 0.8M, besides control over a period of 30 days. It was found that, -carotene and glycine betaine was noticeably increased upto 0.6 M and thereafter declined, whereas proline content increased with increase in NaCl concentrations. The results exhibited that, adaptation of the alga to salinity was characterized by the accumulation of osmolytes like β carotene, glycine betaine and proline. It was attributed that proline accumulation may be one of the major mechanisms of salinity tolerance by the alga.
