Figure 5
The nitrate/nitrite reduction gene clusters that were shared by all the C. testosteroni genomes and the eight other genomes of Comamonadacea . The gene orthologues for different functions are showed in different colors. White arrows indicate genes for other functions that were not correlated with nitrate/nitrite reduction. The breaks in the clusters from A. avenae subsp. avenae RS-1 and V. aporrectodeae subsp. tuberculatae At4 mean that the genes are distributed in different contigs. The dotted line in the cluster from A. denitrificans K601 means that the interval between the genes is very long.
