Leaf peroxidases – A biochemical marker for the group 2 chromosomes in the Triticinae

Abstract
SUMMARY: Structural genes for the leaf isozymes of peroxidases (E.C.1.11.1.7) have been located on chromosome arms 2BS, 2DS and probably 2AS of wheat, 2RS of cereal rye and on chromosome 2H of Hordeum vulgare. This character provides a useful genetic marker for these chromosome arms, and the results supports the notion of the conservation of gene synteny groups within the Triticinae.
