Evolution of Mitochondrial Malate Dehydrogenase in Birds (II)

抄録

This is the second paper on our comparative study of electrophoretic mobility of mitochondrial malate dehydrogenase (M-MDH) in the pectoral muscle or red cells of 100 species of birds belonging to 34 families. Falconidae and Accipitridae showed the same mobility value of 140, while Cathartidae showed 100, which may suggest their terrestrial origin. In Alcidae two groups of the mobility value of 190 (Uria, Cepphus, Brachyramphus and Synthliboramphus) and 100 (Ptychoramphus, Cyclorrhynchus, Aethia and puffins) were distinctively recognized.
