FIG 1.

Sequence analysis of the predicted oriC region of 11 selected Mollicutes of the Spiroplasma group. (A) Phylogenetic tree based on the oriC region sequence of the chromosome using maximum likelihood. The number on each node indicates the percentage with which each branch topology was supported. The tree is drawn to scale, with branch lengths representing the number of substitutions per site. (B) Putative DnaA binding motif found using MEME. (C) Localization of putative DnaA boxes within the intergenic regions upstream and downstream of dnaA. Putative DnaA boxes on positive and negative DNA strands are indicated by red rectangles positioned above and below the chromosomal line, respectively. Regions are drawn to scale. S. citri and S. kunkelii guaB-dnaA intergenic region is cut for presentation purposes, as well as represented genes.
