Lateral Gene Transfer and the Origins of Prokaryotic Groups
Annual Review of Genetics, 2003▪ Abstract Lateral gene transfer (LGT) is now known to be a major force in the evolution of prokaryotic genomes. To date, most analyses have focused on either (a) verifying phylogenies of individual genes thought to have been transferred, or (b) estimating the fraction of individual genomes likely to have been introduced by transfer.

Phylogenetic reconstruction and lateral gene transfer
Trends in Microbiology, 2004Lateral gene transfer (LGT) is often seen as a form of noise, obscuring the phylogenetic signal with which we might hope to reconstruct the evolution of a group of organisms, or indeed the history of all life (the Tree of Life). Such reconstruction might still be possible if the subset of genes conserved among all genomes in a group (or common to all ...

Phage as agents of lateral gene transfer
Current Opinion in Microbiology, 2003When establishing lysogeny, temperate phages integrate their genome as a prophage into the bacterial chromosome. Prophages thus constitute in many bacteria a substantial part of laterally acquired DNA. Some prophages contribute lysogenic conversion genes that are of selective advantage to the bacterial host.

TOWARDS IDENTIFYING LATERAL GENE TRANSFER EVENTS
Biocomputing 2003, 2002This paper is concerned with evaluating the performance of the model and algorithm in 5 for detecting lateral gene transfers events. Using a Poisson process to describe arrival times of transfer events, a simulation is used to generate "synthetic" gene and species trees.

Efficient algorithms for lateral gene transfer problems
Proceedings of the fifth annual international conference on Computational biology, 2001This paper develops a model for lateral gene transfer events (a.k.a. horizontal gene transfer events) between a set of gene trees T1, T2, …, Tk and a species tree S. To the best of our knowledge, this model possesses a higher degree of biological and mathematical soundness than any other model proposed in the literature.

Trends and barriers to lateral gene transfer in prokaryotes
Current Opinion in Microbiology, 2011Gene acquisition by lateral gene transfer (LGT) is an important mechanism for natural variation among prokaryotes. Laboratory experiments show that protein-coding genes can be laterally transferred extremely fast among microbial cells, inherited to most of their descendants, and adapt to a new regulatory regime within a short time.

Lateral gene transfer and the nature of bacterial innovation
Nature, 2000Unlike eukaryotes, which evolve principally through the modification of existing genetic information, bacteria have obtained a significant proportion of their genetic diversity through the acquisition of sequences from distantly related organisms.

Lateral gene transfer in phylogeny of azoreductase enzyme
Computational Biology and Chemistry, 2008This paper attempts to reconstruct the phylogeny of azoreductase enzyme from different organisms and compare it with the small subunit rRNA-based phylogeny of the organisms. The two phylogenies were found to be incongruent, indicating several events of lateral transfer of azoreductase gene between phylogenetically diverse organisms.
