摘要：

Hoechst dye 33258-CsCl density gradients were used to isolate two satellite DNA species from Synura petersenii Korsh. sensu lato, a member of the Synurophyceae. One satellite DNA was identified as the chloroplast genome. The chloroplast genome is the smallest (91.5 kb) published for any chromophyte and approximates the size of the smallest functional chlorophyte chloroplast genome (Codium fragile, 89 kb). The second satellite DNA was small (34.5 kb), and its origin is undetermined. The potential Of using the S. petersenii chloroplast genome in comparative studies for evaluating organellar evolution and algal systematics is discussed.
