Genome degradation in the c-di-GMP signaling pathways and serovar-specific YhjH-YciG interactions rewired motility regulation in Salmonella Paratyphi A

Helit Cohen, Rivka Shem-Tov, Hanan Tawil…·Ohad Gal‐Mor

This paper shows how genome degradation in Salmonella Paratyphi A rewires c-di-GMP signaling and motility regulation through pseudogenization of ycgR and a serovar-specific YhjH-YciG interaction.
