Unbranched heterocytous cyanobacteria exhibit complex filament and colony architectures and variable life strategies from symbionts to free living planktic and non-planktic species. They are counted among microbial groups showing an extensive production of secondary metabolites, resulting in both pharmaceutically important and toxic compounds. The main focus of this thesis is to broaden our knowledge on bioactive secondary metabolite potential in this widespread group of cyanobacteria. An effective combination of methods including whole genome sequencing, bioinformatic analysis, and analytical chemistry techniques are applied to accomplish this task. The discrepancies in distribution of various classes of compounds among ecological groups defined by different life strategies are discussed. Additionally, the thesis endeavours to test multidisciplinary approaches to tackle taxonomic assignments of unresolved unbranched heterocytous cyanobacteria using morphological, phylogenetic and ecophysiological methods, including a meta-analysis of morphological traits.
