ABSTRACT
Despite the general acceptance that classical genetics and modem genetic engineering techniques are powerful and almost essential tools in studying molecular regulation processes, these techniques have not been applied very efficiently to Spirulina. The need for new improved strains to be used for particular purposes is just another reason for the need to develop a gene transfer system and other molecular genetic techniques for Spirulina. When reviewing the available relevant literature on Spirulina, one is surprised to note how little has been done, even in comparison with the work done on other filamentous bluegreen algae.
