Chromosomal location of structural genes controlling isozymes in Hordeum chilense : 1. 6-Phosphogluconate dehydrogenase and malate dehydrogenase.
A study of 6-phosphogluconate dehydrogenase and malate dehydrogenase isozyme expression in Triticum turgidum conv. durum /Hordeum chilense monosomic addition lines has revealed the location of two structural genes, 6-pgd-H (ch) 2 and Mdh-H (ch) 1, on chromosome 1H(ch) of H. chilense. The homoeology between 1H(ch) and other chromosome of Triticeae related species is discussed on the basis of isozyme gene analysis.
