The presence of shared conserved insertions or deletions in proteins (referred to as signature sequences) provides a powerful means to deduce the evolutionary relationships among prokaryotic organisms. This approach was used in the present work to deduce the branching orders of various eubacterial taxa consisting of photosynthetic organisms. For this purpose, portions of the Hsp60 and Hsp70 genes, covering known signature sequence regions, were PCR‐amplified and sequenced from Heliobacterium… Expand
