Local expansion of a panmictic lineage of water bloom-forming cyanobacterium Microcystis aeruginosa.

In previous studies, we have demonstrated that the population structure of the bloom-forming cyanobacterium Microcystis aeruginosa is clonal. Expanded multilocus sequence typing analysis of M. aeruginosa using 412 isolates identified five intraspecific lineages suggested to be panmictic while mainta...
