Genetic control of dipeptidase in the Triticeae.
Isoelectric focusing has been employed to elucidate the genetic control of a series of dipeptidase isozymes in wheat and its relatives. The phenotype of wheat shows four bands, three of which are shown by aneuploid analysis to be controlled by the loci Dip-A1, Dip-B1 and Dip-D1 on chromosome arms 6AL, 6BL and 6DL, respectively. Varietal polymorphism for Dip-A1 and Dip-B1 was observed. Different homoeoloci were found in barley, Haynaldia villosa and Agropyron junceum.
