Dr. Giddy Landan (CAU, Institut für Allgemeine Mikrobiologie): "Origins of major archaeal clades correspond to gene acquisitions from bacteria"

04.12.2014 von 10:15 bis 11:45

Otto-Hahn-Platz 4 (OHP4) - Raum 121

Ein Vortrag im Rahmen des Oberseminars Stochastische Prozesse

Einladender: Prof. Dr. Rösler




Gene transfers identified at major evolutionary transitions among archaea specifically implicate gene acquisitions for metabolic functions from bacteria as key innovations in the origin of higher archaeal taxa. 


New methodology: 

* Comparison of sets of trees without a reference phylogeny. 

* Tree compatibility measures tuned to detect a non-vertical, LGT, signal. 

* Statistics for integration of layered data with small per-layer samples. 



267,568 protein coding genes of: 134 sequenced archaeal genomes, in the context of their homologs from: 1,847 reference bacterial genomes.
