Project description

Earth is inhabited by billions of prokaryotic species, but their speciation and evolution are only poorly understood. Cyanobacteria belong to the most important primary producers thriving in all environments with sufficient light intensity for billions of years. They inhabit extreme environments such as desert soils; therefore, they are adapted to broad temperature fluctuation, high UV radiation, and drought stress. With climate change, the drylands are expanding, and the importance of cyanobacteria is rising. The Ph.D. project will be focused on the investigation of the transcriptome and epigenome response to these stresses (e.g. drought stress) in several species of cyanobacteria. The epigenomic profiles will be investigated at the population and species levels. The expression profiles will be connected with phenotype, epigenome, and genome diversity. Altogether, the result will provide evidence for the role of adaptation, selection, and environment in the speciation of cyanobacteria.

Department of Botany, Palacký University Olomouc. The laboratory is focused on the evolution and taxonomy of cyanobacteria and algae. We established a wide network of collaborations in Europe and the USA (University of North Florida, USA; University of Florida, USA; Uppsala University, Sweden; Natural History Museum London, UK)
