Chromosomal location of structural genes controlling isozymes in Hordeum chilense : 3. Esterases, glutamate oxaloacetate transaminase and phosphoglucomutase.
Polyacrylamide and starch gel electrophoresis of esterase (EST), glutamate oxaloacetate transaminase (GOT) and phosphoglucomutase (PGM) isozymes in Hordeum chilense, Triticum turgidum conv. durum, the amphiploid H. chilense X T. turgidum (Tritordeum), and the durum wheat/H. chilense monosomic addition lines revealed the chromosomal location of one EST locus, two GOT loci and one PGM locus. Loci Est-H (ch)1 and Got-H (ch)2 were found on chromosome 6H(ch),Got-H (ch)3 on chromosome 3H(ch), and Pgm-H (ch)1 on chromosome 4H(ch). These results lend evidence for the assumed homoeology relationships between chromosomes of Triticeae species.
