Synergistic allelochemicals from a freshwater cyanobacterium [PDF]

Proceedings of the National Academy of Sciences, 2010
The ability of cyanobacteria to produce complex secondary metabolites with potent biological activities has gathered considerable attention due to their potential therapeutic and agrochemical applications. However, the precise physiological or ecological roles played by a majority of these metabolites have remained elusive. Several studies
