Arsenic-Redox Transformation and Plant Growth Promotion by Purple Nonsulfur Bacteria Rhodopseudomonas palustris CS2 and Rhodopseudomonas faecalis SS5

Figure 1

NJ-phylogenetic tree of PNSB isolates CS2 and SS5 along with their closest homologues from NCBI nucleotide BLAST results. Sequences were aligned with ClustalW and tree was made in MEGA 5 using 100 bootstrap replicates. Isolate CS2 grouped with Rhodopseudomonas palustris and SS5 grouped with Rhodopseudomonas faecalis.
