INDUCED MUTAGENESIS IN RED ALGA GRACILARI A-VERRUCOSA (HUDS) PAPENF

Biological consequence's of the combined action of gamma-irradiation a nd heteroauxin on the red alga Gracilaria verrucosa were analyzed. The majority of progeny of algae exposed to mutagenic treatment differed from the parental forms. They lost the ability of sexual reproduction and formed more branched and thin thalli. Changes in the pattern of al lozyme variability between the parental and mutant forms were observed . The strain of G. verrucosa obtained by induced mutagenesis may serve as stock for further breeding.
