Genetic Variability in Natural Populations of the Moss Atrichum angustatum
Cummins H and Wyatt R. 1981. Genetic Variability in Natural Populations of the Moss Atrichum angustatum. The Bryologist. 84(1):30-38
An electrophoretic survey of the moss Atrichum angustatum (Brid.) B.S.G. showed varying degrees of staining activity for eight of the ten specific enzymes surveyed. Of the eight active systems, four were scoreable: acid phosphatase, glutamate dehydrogenase, malate dehydrogenase and phosphoglucoisomerase. Comparisons of 15 populations of A. angustatum utilizing these four enzyme systems indicated significant levels of genetic variability both within and among populations. The traditional view of bryophytes as genetically impoverished organisms with severely limited potential for response to natural selection is challenged by these results.
