Draft Genome Sequence of Plantibacter flavus Strain 251 Isolated from a Plant Growing in a Chronically Hydrocarbon-Contaminated Site

ABSTRACT Plantibacter flavus isolate 251 is a bacterial endophyte isolated from an Achillea millefolium plant growing in a natural oil seep soil located in Oil Springs, Ontario, Canada. We present here a draft genome sequence of an infrequently reported genus Plantibacter, highlighting an endophytic lifestyle and biotechnological potential.
