THE MUTAGENESIS OF BENZO (a) PYRENE IN PORPHYRA YEZOENSIS UEDA

Abstract:

Present paper reports benzo(a) pyrene a polycyclic aromatic compound, at the concentrations of 0.02×10^-6, 0.20×10^-6, induced somatic mutration in Porphyra yezoensis Ueda, resulting in the occurrence of various color spots, such as pale purple orange or reddish orange on the algal fronds. Those mutant cells co-existed with the wild unmutant cells in the same frond giving variegated color mosaic mutants. The increasing frequence of color mutant with the rise of concentrations of benzo(a) pyrene was revealed in our experiment.

Key words: Benzo(a) pyrene, Mutagenesis, Porphyra yezoensis
