Electrophoretic variation in acid phosphatases and alcohol dehydrogenases of native greek di ploid species of aegilops aegilops caudata and aegilops comosa poaceae

Electrophoretic variation in acid phosphatases and alcohol dehydrogenases of native greek di ploid species of aegilops aegilops caudata and aegilops comosa poaceae

The acid phosphatase and alcohol dehydrogenase patterns in 5 varieties of A. caudata (genome type C) and A. comosa (genome type M) [A. caudata var. caudata, A. caudata var. polyanthera, A. comosa ssp. comosa var. thessalica, A. comosa ssp. heldreichii var. biaristata and A. comosa var. subventricosa] were studied in order to elucidate the phylogenetic relationships within and between the 2 groups. The raw enzyme extracts of the shoot and the root of 4-day-old seedlings were separated by the use of electrostarch horizontal gel electrophoresis, and the surfaces of the zymograms were evaluated by means of a densitometer. Comparing the band patterns of the 2 enzyme systems studied here and of 2 more further on (esterase, peroxidase, Symeonidis et al. 1979) in 5 varieties of Aequilops, the following conclusions were reached. The similarities of the isoenzymes are larger within the species rather than between the species. The 2 varieties of A. caudata (var. polyathera and var. caudata) demonstrate a close phylogenetic relationship. The A. comosa varieties [subventricosa (= s), var. biaristata (= b), var. thessalica = th)] are found with the following relationship existing between them: .**GRAPHIC**.
