Abstract
|
|
|
|
Fire blight is a fatal plant disease caused by the pathogen Erwinia amylovora on rosaceous plant, especially apple. Serratia rubidaea strain AO4-P6, a biocontrol bacterium against fire blight is isolated from the organic farming soil in Asan-si, Korea. Here, we report the whole genome sequence of S. rubidaea strain AO4-P6. The sequence analysis revealed that S. rubidaea strain AO4-P6 has a single 4,907,279 bp circular chromosome with a DNA G + C-content of 59.2%. This chromosome contains 4,508 protein-coding sequences together with 22 rRNA and 84 tRNA genes. Further genome analysis revealed that strain AO4-P6 possessed the genes related to the production of disease suppressive secondary metabolites, such as safracin, pyrrolnitrin, and siderophore, as well as the genes associated with bacterial competitions such as chitinase, and multi-drug resistance protein.
