The First Molecular Characterization of Picocyanobacteria from the Argentine Sea

Figure 2

Denaturing gradient gel electrophoresis analysis of PCR amplified 16S rRNA gene segments obtained from environmental samples of the Argentine Sea. Syn-GEF.1 (lane 1) and Syn-EPEA.1 (lane 2) isolates were used as references. Lanes 3 and 5: shelf stations 27 and 66, respectively; lanes 4 and 6: oceanic stations 20 and 62, respectively. Labeled bands were excised for further sequencing.
