Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the reduced glutenins of nullisomic- tetrasomic lines of Chinese Spring wheat showed that four glutenin subunits are coded by genes on chromosome 1D. Analogous studies on ditelocentric lines showed that these genes are located on the long arm of chromosome 1D. This conclusion substantiated the fact that four subunits were absent in the durum wheat, LD222, and present in its 1D-1B substitution line. Repression of the synthesis of subunits coded by genes on chromosomes of the A or B genomes was observed in lines tetrasomic for chromosomes 2B, 3B, and 6B.
