Abstract

Genetic research on algae has led to interesting discoveries in the past decade, demonstrating that this approach has much to offer, both intrinsically, and as an aid to phycological studies. In general, genetic research on algae can be divided into three spheres of activity. Of these, the most applied sphere is plant breeding, which is based on measurements of quantitative characteristics found in wild or cultivated populations of seaweeds, and genetic analysis of the measured phenotypic variance. Very little research of this kind exists for algae; currently the only significant breeding efforts are located in the Orient, particularly China, where improvement of Laminaria japonica as an aquaculture crop has been under way for about 25 years (Wu, 1987). The most modern of the three spheres of genetic activity is molecular genetics, with its emphasis on DNA isolation and direct characterization of the plant genome. At present, molecular genetic research is being pursued vigorously for some species of unicellular algae, in particular, members of the genus Chlamydomonas for which an excellent fund of biological and genetic information already exists.
