The hordein polypeptide controlled by the Hrd G (Hor 4) locus in Elgina and derived lines was purified by preparative isoelectric focusing. The amino acid composition was similar to those of the major B hordeins encoded by the Hor 2 locus. Genetic analysis confirmed that Hor 4 is located proximally to Hor 1 on the short arm of chromosome 5. It is speculated that Hor 4 arose by translocation of genes from Hor 2, possibly in an ancestor of Elgina.
