Draft Genome Sequence of the Plant Growth-Promoting Sphingobium sp. Strain AEW4, Isolated from the Rhizosphere of the Beachgrass Ammophila breviligulata

ABSTRACT Sphingobium sp. strain AEW4 is a novel isolate from rhizosphere soil attached to the root of the American beachgrass Ammophila breviligulata. The genomic sequence consisted of 4,678,518 bp and 4,428 protein-coding sequences. Here we report the draft genome sequence of this strain and some initial insights on its plant growth-promoting capabilities.
