ABSTRACT

A significant portion of rye is used as feed or for industrial purposes. World production of rye has been continuously decreasing in recent decades due to the lower yields in comparison to other cereals and limited demand for food purposes. The amino acid composition of total protein in rye and triticale is very similar to that of wheat. The protein content of triticale varies widely depending on the variety and environmental conditions. The genome of octaploid triticale contains all DNAs coding for wheat and rye polypeptides. The low molecular weight storage proteins of rye nearly correspond to the alcohol-soluble portion of endosperm proteins according to the classification system of Osborne. A more effective separation of low molecular weight rye storage proteins became possible with the use of the gel electrophoresis technique. The structure of the high molecular weight storage proteins of rye has not been investigated as thoroughly as that of wheat.
