Rearrangements in gene order in the P. ultimum genome relative to Phytophthora genomes. Vertical brown bars indicate orthologs shared among P. ultimum, Ph. infestans and Ph. ramorum. Gold bars indicate orthologs shared only between Ph. infestans and Ph. ramorum. Turquoise bars indicate genes with orthologs in other regions of the compared genomes (that is, non-syntenic orthologs). Grey bars indicate genes without orthologs. Gray and red shaded connections indicate blocks of syntenic orthologs with the same or opposite relative transcriptional orientations, respectively. Non-coding regions of the genome are not depicted.
