An Enterobacter roggenkampii strain, named KQ-01, was isolated for the first time from the diseased roots of the bacterial wilt-resistant mulberry (Morus atropurpurea) cultivar YS283 in the western part of Guangxi Zhuang Autonomous Region, China. E. roggenkampii KQ-01 was characterized by a single, circular chromosome of 4,667,006 bp in size, with a 56.16% GC content. In total, 4,396 genes were annotated, of which 4,281 were assigned as protein-coding genes. In addition, 25 ribosomal RNA, 84 transfer RNA, and 6 noncoding RNA genes as well as 34 pseudogenes were predicted. The resource herein presented will help to explore the pathogenetic mechanisms of mulberry wilt disease caused by genus Enterobacter.
