Comparative genomics of the plant-growth promoting bacterium Sphingobium sp. strain AEW4 isolated from the rhizosphere of the beachgrass Ammophila breviligulata.

Background: The genus Sphingobium within the class Alpha-proteobacteria contains a small number of plant-growth promoting rhizobacteria (PGPR), although it is mostly comprised of organisms that play an important role in biodegradation and bioremediation in sediments and sandy soils. A Sphingobium sp. isolate was obtained from the rhizosphere of the beachgrass Ammophila breviligulata with a variety of plant growth-promoting properties and designated as Sphingobium sp.

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

sp. strain AEW4 is a novel isolate from rhizosphere soil attached to the root of the American beachgrass 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.
