Deduction of probable events of lateral gene transfer through comparison of phylogenetic trees by recursive consolidation and rearrangementDave MacLeod
GenomeAtlantic, 1721 Lower Water Street, Suite 401, Halifax, NS, B3J 1S5, Canada
BMC Evol Biol 5:27. 2005
..Indeed, even when the true history is a mixture of vertical descent for some genes and lateral gene transfer (LGT) for others, such methods produce unique topologies...

Trends Microbiol 14:64-9. 2006
..Although there might be little evidence for the extensive recent transfer of genes, we demonstrate that ancient lateral gene acquisition has shaped the B. bacteriovorus genome to a great extent...
