| Abstract:
In this work, differential protein expression in olive tissues after salt treatments has been investigated. Olive clones selected in vitro according to their salt tolerance were submitted, also in vitro, to high salt concentrations. After each treatment, the leaves and stems were collected and protein extracts of them subjected to polyacrilamide gel electrophoresis to analyse their band patterns. Some differences were observed referring to 2 bands of approximately 24 kD and 40 kD which appeared in the extracts after exposition to salt. It is discussed the possible implication of this polypeptide in the response of olive tree to salt stress and similarities with other proteins described in other plant species. | |
