Fig. S6. Comparisons of photosynthetic gene clusters among Agromonas oligotrophica S58, Bradyrhizobium sp. ORS278, Bradyrhizobium sp. BTAi1, Bradyrhizobium sp. S23321, and Rhodopseudomonas palustris CGA009. The photosynthetic gene cluster of S58 was highly conserved with those of ORS278 and BTAi1. The gene arrangement of the photosynthetic gene cluster in the S58 genome was very similar to the arrangements in S23321 and CGA009, but it showed lower similarity with pufMLAB of R. palustris CGA009 (shown in red type), as also analyzed by Southern hybridization (see Fig. S2).
