Draft genome sequence of Xanthomonas fragariae reveals reductive evolution and distinct virulence-related gene content.

ABSTRACT:

Background

Xanthomonas fragariae (Xf) is a bacterial strawberry pathogen and an A2 quarantine organism on strawberry planting stock in the EU. It is taxonomically and metabolically distinct within the genus Xanthomonas, and known for its host specificity. As part of a broader pathogenicity study, the genome of a Belgian, virulent Xf strain (LMG 25863) was assembled to draft status and examined for its pathogenicity related gene content.

Results

The Xf draft genome (4.2 Mb) was considerably smaller than most known Xanthomonas genomes (~5 Mb). Only half of the genes coding for TonB-dependent transporters and cell-wall degrading enzymes that are typically present in other Xanthomonas genomes, were found in Xf. Other missing genes/regions with a possible impact on its plant-host
