Abstract
More than 20 Synechococcus and Cyanobium isolates were obtained from central European subalpine lakes and sequenced for their 16S rRNA gene and part of the phycocyanin operon (cpc), specifically the intergenic spacer (IGS) between cpcB and cpcA, and corresponding flanking regions (cpcBA-IGS). Maximum-likelihood analyses revealed the existence of at least six to seven clusters of nonmarine picocyanobacteria within the picophytoplankton clade and support the conjecture of global dispersal for some closely related picocyanobacterial genotypes.Mesh:
