Chromosomal location of adenylate kinase isozymes in Triticeae species.

One system of monomeric adenylate kinase isozymes, designated ADK, was observed in Triticum aestivum and in five diploid Triticeae species. The gene loci Adk-a, Adk-b and Adk-d were located on 7AL, 7BL and 7DL Triticum aestivum cv "Chinese Spring" chromosomal arms, respectively. Adk gene loci were also located on the 7RL chromosomal arm of Secale cereale cv "Ailés", the 7H chromosome of Hordeum vulgare cv "Betzes", 7X of Agropyron intermedium, 7E of Elytrigia elongata and CSU-E of Aegilops umbellulata. The results suport the notion of the conservation of gene synteny groups within Triticeae species.
