The paper describes the integration and excision of a 37-kb element in Anabaena variabilis, mediated by a putative integrase.

This paper shows that a plasmid-encoded type IIB restriction-modification system in cyanobacteria blocks conjugative gene transfer by cleaving foreign DNA, leading to double-stranded DNA degradation.

This study characterizes the nitrogenase genes nifP and nifVZT1 in Anabaena variabilis, showing they are cotranscribed but have distinct promoters and regulatory mechanisms.
