Genetic exchange in bacteria/archaea OEB 192 – (Worobey et al., 2010, last Friday)

Two “types” of HGT…

Comparison of HGT to “normal” sex

Detecting HGT: unlikely presence/absence HGT onlyLoss only (Koonin, 2003) Ex: glycerol-3-P DH

Detecting HGT: differential gene content (Welch et al., 2002)

Detecting HGT from genomes: atypical nt composition (Hacker & Carniel, 2001)

GC% bias across species (Lawrence & Ochman, 1997)

Wednesday (9/22): Limits to HGT
