요약 | Erwinia amylovora is the causative agent of fire blight disease of apple and pear trees, causing annual losses of over 100 million USD in the USA. E. amylovora cells are disseminated to new hosts by insects, wind, and rain, and then invade susceptible tissues and migrate systemically throughout the host, requiring coordinate regulation of several virulence factors, including production of the exopolysaccharides amylovoran and levan, biofilm formation, flagellar motility, and type III secretion. Complex regulatory mechanisms have evolved in E. amylovora that occur at the transcriptional, post-transcriptional, and post-translational levels to control these virulence factors. In my work, I analyze the role of small RNAs (sRNAs) as post-transcriptional regulators of virulence-associated traits in E. amylovora.The Hfq chaperone protein stabilizes sRNAs in the cell, allowing them to interact with and regulate mRNA targets. An hfq mutant differs from wild-type cells in several virulence-associated phenotypes including production of the exopolysaccharides amylovoran and levan, biofilm formation, flagellar motility, and type III secretion. E. amylovora encodes at least 40 Hfq-dependent sRNAs |
