Abstract
A serious abiotic stress in the world is salinity, which leads to great losses in the quality and quantity of products in agriculture. To investigate the tolerance mechanisms to salinity, a two-dimensional electrophoresis approach was adopted to visualize proteins achieved from the second-freshly-developed leaf of canola cv. Safi-7 seedlings, after plants had been treated with 0 and 300 mmol/L NaCl. Treatment with NaCl (300 mmol/L) significantly decreased the fresh and dry weights as well as the plant height, and promoted the proline content compared with the control group. Any changes were not significant neither quality nor activities of catalase and peroxidase. Out of 110 repeatable protein spots, 37 spots were differentially changed according to induction factor index. Among differentially changed proteins, five were significantly showed the changes. These proteins have roles, to produce the energy, and scavenge and suppress ROS, and in photosynthesis.
