Abstract
CRISPR-Cas are adaptive immune systems of prokaryotes. In my lab, we study under what ecological conditions CRISPR-Cas immunity is favoured over mutation of the phage receptor and vice versa, and how these two mechanisms shape the population and coevolutionary dynamics of bacteria-phage interactions. In my talk I will also discuss conditions where carrying CRISPR-Cas systems is maladaptive (i.e. selected against), which may explain why approximately 60% of bacteria do not encode CRISPR-Cas immune systems.
