Gene regions found absent in the genome of X. fragariae LMG 25863, together with their occurrence in the complete genomic sequences of 4 other Xanthomonas species compared in EDGAR: i) the glyoxylate shunt pathway genes, ii) the genes coding for a phenolics degradation pathway, iii) the structural genes of a potassium transporter and iv) the three loci for xylan degradation. Gene regions retrieved from each genome are labeled with the locus tags of their respective first and last genes. Absent or incomplete gene clusters are marked in grey. ^a5′-truncated homolog of kdpA [Genbank:NP_636094].
