Shikimate dehydrogenase – a biochemical marker for group 5 chromosomes in the Triticinae

Abstract
Structural genes for the isozymes of shikimate dehydrogenase (E.C. 1.1.1.25) have been located on chromosome arms 5AS, 5BS and 5DS of wheat, 5RS of cereal rye and on chromosome 5Cu of Aegilops umbellulata by electrophoretic techniques. This character provides a useful genetic marker for these previously unmarked chromosome arms, and the results support the notion of the conservation of gene synteny groups within the Triticinae.
