Summary Dickeya dadantii is a plant pathogen that causes soft rot disease on vegetable and potato crops. To successfully cause infection, this pathogen needs to coordinately modulate the expression of genes encoding several virulence determinants, including plant cell wall degrading enzymes (PCWDEs), type III secretion system (T3SS) and flagellar motility. Here, we uncover a novel feed‐forward signalling circuit for controllin...

Summary D ickeya dadantii is a globally dispersed phytopathogen which causes diseases on a wide range of host plants. This pathogen utilizes the type III secretion system ( T3SS ) to suppress host defense responses, and secretes pectate lyase ( P el) to degrade the plant cell wall. Although the regulatory small RNA (s RNA ) RsmB , cyclic diguanylate monophosphate (c‐di‐ GMP ) and flagellar regulator have been reported to affec...
