The work reported here was concerned in an effort to determine number, approximate quantity, and compositions of water-soluble proteins of crops in relation to their salt tolerance. Fractionation was carried out with electrophoresis on polyacrylamide gel at pH 8.9.
The extractable proteins of control crops consisted of 9-11 electrophoretically detectable components in leaf blade and 6-7 components in root.
The changes appeared in the pattern with the development of salt tolerance in saline crops. These changes were produced by shifts in the concentrations of some components related to other components and in the numrber of bands located in cathodic portion of the pattern.
