Draft genome of a Xanthomonas perforans strain associated with pith necrosis.

Xanthomonas perforans causes bacterial spot of tomato and pepper. A genome draft of an unusual isolate (strain 4P1S2), differing in that it was associated with stem pith necrosis, was assembled from Illumina MiSeq sequencing data using the draft of X. perforans strain 91-118 as a reference. The resulting draft (accession number JRWW00000000) largely overlapped with the reference draft. In addition, the reads not mapping on the reference assembly were selected and used for a further assembly, that revealed a large putative plasmid. The analysis of the predicted proteins showed only few gene features that could be potentially implicated in the switch of a phytopathological behavior.
