4蘚類群におけるペルオキシダーゼ・イソ酵素の比較研究(第9回大会講演要旨)

抄録

A comparative study on the isozyme peroxidase patterns of 37 moss species belonging to four groups was made by using starch gel electrophoresis. The four groups were Thuidium (4 species), Hypnum (6 spp.), Fissidens (11 spp.), and Mniaceae (16 spp.). In most of these species the zymograms showed a very small number of bands, one or two, and they were different from those of the higher plants which had a large number of bands. In some groups, such as Thuidium and Mniaceae, the principal results obtained from the intra and interspecific comparisons of the isozyme patterns appeared to be in fairly good agreement with those of the previous karyological or taxonomical studies. In the other group, Hypnum species showed considerable variability, and it seemed to be useful for the analysis of population. From this study it was concluded that the usefulness of isozyme patterns in the taxonomy of bryophytes seemed to be varied from group to group.
