We aim to investigate the cellular organisation and regulation of the viral infection cycle with the main focus on the lysogeny management system of phage SPβ, a prophage of the Gram-positive model organism B. subtilis 168. This phage carries a novel, complex and previously unseen lysogeny management system. Its sophistication has already been demonstrated through the discovery of the arbitrium system (decision making), the initial step of lysogeny establishment.
