Effect of preparations Methyure and Ivine on Са(2+)-ATPases activity in plasma and vacuolar membrane of corn seedling roots under salt stress conditions

| Summary: | Ca2+-ATPases regulate the functioning of Ca2+-dependent signaling pathway SOS which provides removal of Na+ from the cytoplasm of cells via Na+/H+-antiporters in saline conditions. The influence of synthetic preparations Methyure and Ivine on the Ca2+-ATPase activity was investigated. It was shown that exposition of corn seedlings in the presence of 0.1 M NaCl rather enhanced hydrolytic than transport activity of Ca2+-ATPases in plasma and vacuolar membrane of root cells. It was found that seed treatment with such preparations, especially Methyure, caused intensification of the both activities of Ca2+-ATPases, mainly in vacuolar membrane. The results indicate than salt protective activity of preparations, especially Methyure, is associated with increased Ca2+-ATPase activity, which regulates the functioning of Na+/H+-antiporters. |
