ABSTRACT

It should be noted that Synechococcus PCC7002 is presumed to be a natural unicellular mutant, derived from Oscillatriales (to which the commercially useful microalga, Spirulina, belongs), because Synechococcus PCC7002 is more closely related to Phormidium Jraigile PCC7376 by 165 rRNA analysis than to other Synechococcus species (Wtlmotte 1995).
