Lateral gene transfers (LGT) (also called horizontal gene transfers) have been a major force shaping the Thermosipho africanus TCF52B genome, whose sequence we describe here. Firmicutes emerge as the principal LGT partner. Twenty-six percent of phylogenetic trees suggest LGT with this group, while 13% of the open reading frames indicate LGT with Archaea.
