Abstract EN
Picocyanobacteria are abundant throughout the world’s oceans.
Particularly, it has been reported that Synechococcus strains have a wide latitudinal distribution, from polar to tropical waters.
However, their molecular characterization in the Southwest Atlantic Ocean is still missing.
We analyzed Synechococcus genetic diversity in a sector of the Argentine Sea, one of the richest biological areas of the world oceans.
16S rRNA amplicons obtained after PCR amplification of environmental DNA extracted from water samples of this area were used for DGGE and sequenced.
Only Synechococcus sequences could be retrieved.
On the other hand, we isolated two Synechococcus strains from the environment.
Our analyses revealed that the clade I group was widespread from latitude 38°S to 48°S and that can coexist with clade IV strains in shelf waters.
The cooccurrence of these two clades may be related to an adaptation to high-nutrient/low-temperature waters.
Our data are the first report on Synechococcus ecotypes that would be important contributors to phytoplankton biomass in the Argentine Sea, one of the richest biological areas of the world oceans.
