Functional Integration
Shared Genome Resource
Selection
We propose to investigate horizontal gene flow in
bacteria by integrating genomic analysis,
microbial ecology, and experimental selection
systems. Established and novel approaches
performed by a diversely talented team of
investigators will integrate results in a
check-and-balance system. Using three
phylogenetically distinct lineages of bacteria,
we will investigate and quantify the shared
genome resource available for transfer and the
functional integration of that shared resource.
The proposed research and interdisciplinary
training will initiate a comprehensive framework
in which to view prokaryotic genome evolution.
