Lateral gene transfer, rearrangement, reconciliation. [PDF]
BMC Bioinformatics, 2013 Background. Models of ancestral gene order reconstruction have progressively integrated different evolutionary patterns and processes such as unequal gene content, gene duplications, and implicitly sequence evolution via reconciled gene trees.

Lateral gene transfer as a support for the tree of life. [PDF]
Proc Natl Acad Sci U S A, 2012 Lateral gene transfer (LGT), the acquisition of genes from other species, is a major evolutionary force. However, its success as an adaptive process makes the reconstruction of the history of life an intricate puzzle: If no gene has remained unaffected during the course of life's evolution, how can one rely on molecular markers to reconstruct the ...

Lateral gene exchanges shape the genomes of amoeba-resisting microorganisms [PDF]
Frontiers in Cellular and Infection Microbiology, 2012 Based on Darwin’s concept of the tree of life, vertical inheritance was thought to be dominant, and mutations, deletions and duplication were streaming the genomes of living organisms.

Uncovering rate variation of lateral gene transfer during bacterial genome evolution [PDF]
BMC Genomics, 2008 Background Large scale genome arrangement, such as whole gene insertion/deletion, plays an important role in bacterial genome evolution. Various methods have been employed to study the dynamic process of gene insertions and deletions, such as parsimony ...

Aphids acquired symbiotic genes via lateral gene transfer [PDF]
BMC Biology, 2009 Background Aphids possess bacteriocytes, which are cells specifically differentiated to harbour the obligate mutualist Buchnera aphidicola (γ-Proteobacteria). Buchnera has lost many of the genes that appear to be essential for bacterial life.

Unconventional lateral gene transfer in extreme thermophilic bacteria [PDF]
International microbiology : the official journal of the Spanish Society for Microbiology, 2012 Conjugation and natural competence are two major mechanisms that explain the acquisition of foreign genes throughout bacterial evolution. In recent decades, several studies in model organisms have revealed in great detail the steps involved in such ...

Lateral gene transfer: when will adolescence end [PDF]
Molecular Microbiology, 2003 The scope and impact of horizontal gene transfer (HGT) in Bacteria and Archaea has grown from a topic largely ignored by the microbiological community to a hot-button issue gaining staunch supporters (on particular points of view) at a seemingly ever ...

Lateral Gene Transfer Between Protozoa-Related Giant Viruses of Family and Chlamydiae [PDF]
Evolutionary Bioinformatics, 2018 Obligate intracellular chlamydiae diverged into pathogenic and environmental chlamydiae 0.7-1.4 billion years ago. While pathogenic chlamydiae have adapted to a wide range of vertebrates, environmental chlamydiae inhabit unicellular amoebae, the free ...

On surrogate methods for detecting lateral gene transfer [PDF]
FEMS Microbiology Letters, 2001 Surrogate methods for detecting lateral gene transfer are those that do not require inference of phylogenetic trees. Herein I apply four such methods to identify open reading frames (ORFs) in the genome of Escherichia coli K12 that may have arisen by lateral gene transfer.

The source of laterally transferred genes in bacterial genomes [PDF]
Genome Biology, 2003 Laterally transferred genes have often been identified on the basis of compositional features that distinguish them from ancestral genes in the genome. These genes are usually A+T-rich, arguing either that there is a bias towards acquiring genes from donor organisms having low G+C contents or that genes acquired from organisms of similar genomic base ...
