Abstract
AbstractStructural genes for leaf dimeric phosphatases (E.C. 3.1,3.2.) have been located on wheat chromosome arms 7BL and 7DL. No gene was found on 7AL. The results obtained pointed to the existence of two kinds of wheat phosphatases (monomers and dimers j located on different homoeologous groups, which is in agreement with results found in Secale cereale and Agropyron intermedium. These results allow homoeologous relationships to be established through the classification of dimeric phosphatases and also provides another useful genetic marker for the 7BL and 7DL arms., They also provide further support for die concept of the conservation of gene synteny groups within the Triticnae.
