October 31, 2001: Genomic Sequence of a Specific Strain of Filamentous Cyanobacterium Anabaena sp. was Completed
The complete genomic sequence of a filamentous cyanobacterium, Anabaena sp. strain PCC 7120, was completed by an internatioanl team led by Takakazu Kaneko, Japanese microbiologist. The result was published in October, 2001, and revealed a total of 5368 potential protein-encoding genes in its chromosome. Among the whole genome, 28% of the protein-encoding genes sequenced were not found in the exist public DNA databases at that time. Anabaena is an important bacteria in agricuture for its nitrogen-fixing ability. The revelation of its genomic sequence helped scientists to study the genes related to nitrogen fixation and to select bacteria with strong nitrogen-fixing ability, which might help reducing the usage of chemical fertilizer.
