Hypothesis
Members of the two separate phyla Planctomycetes and Verrucomicrobia might share a similar ultrastructure plan differing from classical prokaryote organization.
Conclusion
A unique compartmentalized cell plan found in Planctomycetes has also been identified in Verrucomicrobia, suggesting a shared evolutionary trait.
Supporting Evidence
- Four species of Verrucomicrobia were examined and found to have a compartmentalized cell structure.
- The cell plan is characterized by a major organelle containing DNA and ribosomes.
- This structure is similar to that found in Planctomycetes, suggesting a shared evolutionary history.
- At least three of the six subdivisions of Verrucomicrobia exhibit this cell plan.
Takeaway
Scientists looked at tiny bacteria and found that some of them have a special way of organizing their insides, similar to other bacteria, which helps us understand how they might be related.
Methodology
Electron microscopy techniques including high-pressure freezing and cryosubstitution were used to examine the ultrastructure of four Verrucomicrobia species.
