The response of Raphanus sativus to salinity has been investigated. Salt-responsive proteins were detected by comparative 2D-PAGE analysis. Three polypeptides of 22, 28 and 28.5 kDa were isolated and subjected to microsequencing. The P22 possesses homology with members of the Kunitz family of trypsin inhibitor; the P28.5 is homologous to ascorbate peroxidase of several plant species while P28 did not exhibit significant homology with sequences archived in available databases.
