Abstract
Microcystis aeruginosa is a bloom-forming cyanobacteria, which currently has a cosmopolitan distribution. Since M. aeruginosa can produce toxic compounds across all continents that it inhabits, it is of major public health relevance to assess its origin and dispersal. Thus, we conducted a worldwide study using 29 isolates representative of all the main continents, and used a concatenated genetic system for phylogenetic analyses consisting of four genetic markers (spanning ca. 3,485 bp). Our results support an early origin of M. aeruginosa in the African continent, with a subsequent dispersal to establish a second genetic pool in the European continent, from where M. aeruginosa then colonized the remaining continental regions. Our findings indicate that the European population has a cosmopolitan distribution, and is genetically closer to populations from Africa and North America. Our study also highlights the utility of using a concatenated dataset for phylogenetic inferences in cyanobacteria.
