Hypothesis
EFL has spread by horizontal gene transfer and replaced EF-1α multiple times in green algae.
Conclusion
The distribution of EFL and EF-1α in green algae indicates a complex evolutionary history of both genes.
Supporting Evidence
- EFL is found in all major lineages of green algae except charophyceans and Acetabularia.
- The presence of EFL in Mesostigma and EF-1α in Acetabularia is contrary to expectations based on their relatives.
- The phylogeny of EF-1α shows it was present in the common ancestor of the green lineage.
Takeaway
This study looks at two important proteins in green algae and finds that their presence is more complicated than previously thought.
Methodology
The study sampled EFL and EF-1α from representatives of all major lineages of green algae.
Limitations
The phylogeny of EFL is poorly resolved, making it difficult to draw definitive conclusions.
