Functional distribution of the 135 Groups of Orthologous Elements (GOEs) that have been identified in the genomes of these strains through SSH analysis. These sequences were obtained after alignment of sequenced SSH clones from each strain. The consensus sequences for each contig were filtered against the genome of Xf strain 9a5c and the remaining sequences were analyzed with GeneMark to identify new ORFs. The sequences from such ORFs have been clustered and the resulting contig consensuses (or singlet sequences) have been submitted to Blastx analyses against the GenBank. Functional classification was done according to Simpson and coworkers .
