Figure 4

Alignment of plant associated bacteria solos. LuxR solos and selected sphingomonad LuxR homologs. Number above the alignment corresponds to the residue number of the TraR protein. Regions highlighted in yellow indicate the invariant sites of canonical LuxR homologs (Fuqua and Greenberg, 2002) while variation from the conserved site was highlighted in green. The conserved sites corresponding to autoinducer binding and DNA binding were indicated by blue and purple triangles, respectively.
