Virulence Regulation and Lifestyle Transitions in <i>Erwinia amylovora</i>.

Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a destructive disease of economically important pome fruits, including apples and pears. This study insights will advance our understanding of pathogenicity and lifestyle transitions throughout the pathogen’s life cycle, while also providing an evolutionary perspective on the roles of TCSs and c-di-GMP signaling systems.
