The bacteriophage‐derived transcriptional regulator, LscR, activates the expression of levansucrase genes in Pseudomonas syringae

What is it about?

A bacteriophage-derived regulatory protein has been identified as being controlling bacterial chromosomal genes. This finding suggested that bacteriophages can alter a bacterial host organism not just by adding genes to its genome but also by altering its gene expression. Here, it is demonstrated for a plant pathogen and one of its fitness determinants, exopolysaccharide synthesis.
