| The Effect of Ecdysterone on the Cyanobacterium Nostoc 6720  | | | | Abstract
| The insect hormone ecdysterone stimulated dinitrogen fixation, heterocyst formation, cell size and protein synthesis in suspension cultures of the cyanobacterium Nostoc 6720 within 48 h when added to the culture at concentrations between 10-9 and 10-7 M . In the presence of the hormone the volume of vegetative cells increased by 6-fold and that of heterocysts by near ly twice as compared to untreated controls. All the observed effects were inhibited by the cal-cium-calmodulin inhibitor, trifluoperazine. Cholesterol used as a null control had no signifi cant effect. | | | |
