摘要：

Structural gene loci encoding the monomeric isozymes nicotin adenin dinucleotide dehydrogenase (NADH dehydrogenase or NDH) have been located on the 4AL, 4B-alpha, and 4DS chromosome arms of Triticum aestivum cv "Chinese Spring", on the 4RS chromosome arm of Secale cereale cultivars "Imperial", "King II", "Dakold," and "Ailes," on the 4S1S/7S1 chromosome of Aegilops longissima, the 4E of Elytrigia elongata, and the CSU-A of Aegilops umbellulata. All the results support the homoeologous relationships among these chromosomes in the five species studied. In addition, a map of the 4RS chromosome arm in cv "Ailes" has been realized, linking loci Pgm-1 (located on the 4RS chromosome arm) and Ndh-1 (17.91 cM), with an estimated distance between both loci and the centromere of 20.00 cM and 32.12 cM, respectively.
